CONVENTIONS USED IN THIS MANUAL
Every time a button, an LED or any other control is referenced, it is done by the
number that has been associated to it in the drawings found in chapters 3 to 8. When
you're invited to “press & hold” a button, it is intended that the button should be kept
depressed for at least 2 seconds.
You will find that some concepts might be repeated more than once, this happens
because there could be a mention in a chapter, and a detailed explication in a later
chapter.
We recommend you to read this manual with the instrument in front of you, so you
can put into practice what you are reading and you can have an instant feedback of
the notions here explained.

1. THE SOUNDS OF MOJO 61
VB3-II virtual tonewheel organ
This is the exact same software that powers the Crumar Mojo and
presents the same parameter set. VB3-II is the result of 12 years of
study, research, experimentation and development of the simulation
of a vintage Hammond B3 organ. It is the evolution of the GSi VB3 1.4
which is still available as a plugin for digital audio workstations. In the
last 5 or 6 years it has been considered the best simulation of a
tonewheel organ by some of the most acclaimed jazz and rock
organists and organ techs. The Crumar Mojo has been a best-seller in the "Clone
Organ" market during 2013 and 2014 and now the new Mojo 61 offers you the
possibility to take advantage of one of the best clone organs ever without
compromises.
Pipe Organ
A pipe organ is not something you see every day, there are
thousands of different pipe organs that differ by the number of
stops, the number of manuals, the number and the type of pipes,
their size, their position, etc. but we wanted to keep it simple and
offer a pipe organ that would be easy to understand and inspiring to
play, so we chose to offer a Baroque-style organ based on a single
manual and 9 stops plus 3 couplers and the classic "tremulant" effect.
This synth engine works as an hybrid synthesizer, uses additive synthesis and
physical modeling, there are no samples involved. The expression pedal responds
naturally and varies the amount of air that passes through the pipes. There is a total
of 776 virtual pipes.
Combo Organs
The Mojo 61 features two simulations of very famous Italian
transistor organs of the seventies, the VOX Continental and the
Farfisa Compact DeLuxe. Each of these organs is simulated in every
detail, reproducing the essence and the exact color of that gritty
organ sound that was the cornerstone of rock bands like the Doors,
the Pink Floyd and similar. The polyphony is full (all 61 notes at the
same time) and all controls behave exactly like in the original
instrument. One note: since both these organs were originally based on 49-note
keyboards, we chose to bring the pedalboard tones to the first octave. The
pedalboard tone has no settings.
CRUMAR MOJO 61 USER'S MANUAL - Page 4/32

Tines Electric Piano
There's no keyboardist without a good Rhodes electric piano sound.
And the Mojo 61 offers what can be considered the best fusion
between sound fidelity and playability. This synth engine is based on
more than 10 years of experience on the physical modeling
simulation of a Rhodes electric piano, everything in the "body" of
each single note from the attack transient to the very last decay is
purely simulated. Some minor elements are added from selected
sampled sources, but the most important part of the sound is pure synthesis. Every
element of the mechanical piano is virtually reconstructed in the Mojo 61, from the
hammer, the hammer-tips, the tines, the tonebars, the pick-ups, the dampers, the
output filter straight to the output jack, and they all behave exactly like in the real
thing. Each of the 88 notes is simulated individually, and each note is a generator on
its own, thus offering the full polyphony, no note stealing and a very natural and true
to the original behavior. Plus, this new simulation features a very realistic
sympathetic resonance that involves the whole "harp" that can vibrate and resonate
every time a key is struck. It is really hard to tell the Mojo simulation from a real
Rhodes piano, the level of realism and the number of details is very high.
Reed Electric Piano
Similarly to the previous instrument, the simulation of a Wurlitzer
200A electric piano is totally based on physical modeling with only a
minor addition of sampled material. Same technique as before, every
part of the mechanical piano is virtually reproduced in order to
obtain the maximum level of realism and playability, including the
sympathetic resonance. This piano has 64 notes and all of them can
play at the same time.
Clavi Electric Piano
What's the funkiest keyboard ever? The Clavinet D6! And it's also one
of the most sought-after vintage keyboards of the 2000's and
probably one of the rarest to find on the used market. The Mojo 61
offers a simulation that will literally blow you away! This is pure
physical modeling, no samples were used whatsoever and every
single note is a generator on its own, just like the previous three
instruments in this list. Every detail from the original stringed
keyboard instrument is simulated and the polyphony, once again, is full (60 notes).
This electric piano has no sustain pedal, but still it behaves like any other electroacoustic instrument, has sympathetic resonances, reproduces the woollen yarn
damper sound upon note release, and offers the exact same control set as a Clavinet
D6: there are the four filters, the two pickup selectors and the damper lever. If you
listen close enough, you'll also notice that the first 23 strings are round wound
resulting in a fuller sound than the rest of the keyboard. No detail was left out in this
simulation!
CRUMAR MOJO 61 USER'S MANUAL - Page 5/32

Acoustic Grand Piano
This sample-set comes from the factory sample library of the GSi Gemini and is based
on the GSP-01 "Adaptive Sample Player" synthesis engine. It features a special
"Physical Modeling Piano Harp Resonance Simulator" that adds natural
resonances to the sound mimicking the behavior of a real piano harp. This is the only
sound of the Mojo 61 that is mostly based on pre-recorded material and has no
editing parameters.
Please note: each keyboard instrument simulated by the Mojo 61
respects the keyboard extension of the original instrument, so the
tonewheel organ allows 61 notes for the two manuals and 25 notes for
the bass pedalboard, the Pipe Organ allows 61 notes, both Combo
organs feature 49 notes plus 12 bass notes on the first octave, the Tine
piano allows up to 88 notes, the Reed piano allows 64 notes, the Clavi has only 60
notes (please notice that the first 5 notes of the keyboards will be muted), and the
Acoustic Piano has 88 notes.
CRUMAR MOJO 61 USER'S MANUAL - Page 6/32

2. THE EFFECTS
Tremolo / Auto-panner / Wha-Wha
Mojo 61 offers electric pianos and organs, so how could we miss such important
effects in the chain? The Tremolo is a must in mono mode when combined with the
Reed EP, and sounds great in square stereo with the Tines EP. And the Wha-Wha
sounds so funky in combination with each and every piano sound.
Stereo Phaser
This is a 4-stage stereo phaser (two individual phasers slightly shifted), and offers
parameters such as LFO speed and depth. Sounds great on the electric piano sounds.
Stereo Chorus
We've been listening to a selection of chorus effects for keyboards and guitars,
ranging from the early analog BBD choruses up to the modern digital ones, but one
that works really great on a vast variety of sounds is the two-voice BBD-based stereo
chorus that Roland included in the RD-1000 and in many others of their instruments
of the eighties. This is a simulation of that very chorus and sounds really great with
the electric pianos.
Amp Simulator
And here comes the boutique amp collection. This processor simulates five among
the most used guitar and bass amps of all times: the Fender Twin, the Marshall JCM800, the Vox AC30, the Roland Jazz Chorus and the Fender BassMan. Each amp
features a 3-way equalizer and an adjustable overdrive.
Rotary Effect Simulator
There's no VB3-II without a great rotary effect. This is the exact same rotary effect
featured in the Crumar Mojo, offering the same control set and the same sound.
Digital Reverb
This is a great sounding digital reverb that brings light and air to your sound. Sounds
soft, smooth and deep, precise and alive, airy and so much realistic that's a real joy to
have some in the mix.
Equalizer
This section contains a very basic 3-band equalizer. Use it to shape your sound for a
perfect match with your amplification system.
CRUMAR MOJO 61 USER'S MANUAL - Page 7/32

3. THE COMMAND PANEL – part 1
In this chapter we get familiar with the command panel of the Mojo 61; for a better
readability, the panel has been split into three parts. Numbers are used to reference
to each control later in this manual.
1. Volume knob.
2. Drive knob, adjusts the overdrive level when the Rotary Speaker effect is active
on VB3 and when a Static Amp is active on Combo organs or Electric Pianos.
3. RUN/STOP: press to stop the rotation of the Rotary Speaker effect, the
corresponding LED will turn on; press again to re-start the rotation, the LED will
go off.
4. SLOW/FAST: press to switch between the two speeds of the Rotary Speaker
effect. The corresponding LED animates accordingly. Please note that the LED
animation is not synchronized with the sound, it's only there for a better visual
feedback. When the STOP speed is engaged, the LED animation halts.
Depressing this button while in STOP mode will switch the speed and the LED
will start animating again, even though there will be no effect on the sound until
the STOP is disengaged using button n. 3.
5. This LED indicates that the support for the optional “Half-Moon” switch has been
enabled, in this case buttons 3 and 4 are unresponsive. To enable and disable the
“Half-Moon” support, press buttons 3 and 4 together.
6. Press this button to switch cyclically between the Vibrato/Chorus options. When
playing VB3, there are 6 options (C1, C2, C3, V1, V2, V3); when playing the Combo
organ “Compact DeLuxe” , only 4 options are available (labeled with smaller
characters, explained later).
7. This button enables/disables the Vibrato/Chorus effect on the selected manual.

4. THE COMMAND PANEL – part 2
8. Presets for the upper manual.
9. Upper manual selector / Upper HOLD function.
10. The drawbars. These are used for all organ sounds the Mojo 61 offers.
11. Presets for the lower manual.
12. Lower manual selector / Lower HOLD function.
13. This LED indicates the status of the “Pedal-to-lower” function that can be
enabled and disabled by pressing button n. 14 and then button n. 12.
Since firmware 1.40, it's possible to keep the PEDALS button depressed for 2
seconds to activate a split between the pedalboard and the lower manual.
14. Pedalboard selector.
15. MODE selector. Press to switch between SINGLE and SPLIT, press and hold to
activate the EXT-LOWER mode.

5. THE COMMAND PANEL – part 3
16. Knobs for adjusting the Reverb level and the amount of key-click produced by
VB3 and the Combo organs.
17. Equalizer section, works on top of everything.
18. Multi-function button n. 1.
19. Multi-function button n. 2.
20. Multi-function button n. 3.
21. Multi-function button n. 4.
22. Instrument type selection. Press this button to cycle between the four basic
sounds (VB3, Pipe organ, Combo organ, Electric piano) from top to bottom.
Pressing this button along with the SHIFT button cycles from bottom to top.
23. This LED indicates whether the transposition has been enabled.
24. This LED indicates the status of the Rotary Speaker effect or the Static amps.
25. This LED indicates whether the LOCAL-OFF function has been enabled. In a
normal playing situation this LED should be off.
26. The SHIFT button. It is used in conjunction with other buttons for alternate
functions and shortcuts that will be explained later in this manual.
CRUMAR MOJO 61 USER'S MANUAL - Page 10/32
Fig. 3 - Command Panel part 3

6. THE REAR PANEL
1. Analog, line level, balanced, stereo audio output. Use your jack cords to connect
the Mojo 61 to your amplification system. Preferably, use balanced cables.
2. Output level selection. The optimal choice is to leave this selector in the middle
position (+4 dB); if you're connecting it to a home “consumer type” hi-fi system,
use the “L” position (-10 dB); for more power use the “H” position.
3. Headphone output, max load = 32 ohm (check with your headphone specs).
Best performance with studio grade 55 ohm headphones.
4. If you forgot your Wi-Fi password for accessing the Editor web-app, use a small
screwdriver or a sharp pencil to push the button that hides behind this hole. The
password will be re-set to “00000000” and the system will restart automatically.
5. System USB 2.0 Type “A“ ports, used for firmware updates and other connections.
6. These are two MIDI inputs internally merged together. If you want to connect an
external keyboard to control your Mojo 61, just pick one of the two, they're
identical. There are two because you might also want to connect a pedalboard,
so you don't need an external MIDI Merger unit.
7. Your Mojo 61 can also be used to control other MIDI equipment, this is the usual
MIDI output socket.
8. Class-compliant USB-MIDI IN/OUT port, can be used to connect the Mojo 61 to
your computer without using an external MIDI interface.
CRUMAR MOJO 61 USER'S MANUAL - Page 11/32
Fig. 4 - Back panel part 1.
Fig. 5 - Back panel part 2.

7. CONNECTING CONTROL ACCESSORIES
There are three additional Jack sockets on the back of the Mojo 61 that are used to
connect pedals or the “half-moon” 3-way switch.
9. Half-Moon or Foot Switch input socket. Here you can connect our dual foot
switch or our half-moon switch; the latter can only be attached to the optional
lower manual keyboard, and is activated by pushing buttons n. 3 and n. 4
together. Normally, this socket accepts the dual foot switch that works
concurrently with the panel buttons n. 3 and n. 4. Please make sure to use a foot
switch specifically made for the Mojo 61.
10. Connect a 10-K ohm expression pedal to this jack; our Crumar long-throw pedal
is the perfect choice, but other third party pedals might be compatible as well.
11. Connect a traditional sustain pedal to this jack; the polarity is automatically
detected when the instrument is powered on, so please make sure that the
pedal is already connected before powering on.
ABOUT THE SUSTAIN PEDAL
The sustain pedal is normally used when the Electric Piano sound is active and
functions as a normal piano sustain pedal. However, when VB3 is active and the
Rotary Speaker effect is on, the sustain pedal can be configured in a variety of ways
by selecting the proper option in the editor's home page. It can switch Rotary speeds
in latched or momentary mode, sustain the upper, the lower or both manuals, or just
send the MIDI CC # 64 (pedal hold as per General Midi specifications).
8. HOW TO TURN THE MOJO 61 ON
The Mojo 61 comes with an AC cable, one end goes to the power
outlet, the other end goes to the power socket on the back of the
instrument, labeled with number 13.
Push the switch n. 12, after a second you will see all the lights
illuminating the control panel, and after 8 more seconds the
instrument is ready to be played.
CRUMAR MOJO 61 USER'S MANUAL - Page 12/32
Fig. 6 - Pedal inputs.
Fig. 7 – Power section.

9. ALL ABOUT VB3
VB3 is the first instrument that can be selected by pushing the button n. 22 labeled
TYPE. It is the simulation of a tonewheel organ and is the main sound engine of your
Crumar Mojo 61. Just like the original organ, it consists of three manuals, the upper,
the lower and the pedalboard, even though we have only one physical keyboard and
one set of 9 drawbars. Nevertheless, Mojo 61 offers some smart solutions to make it
fun and easy to play even without the additional lower keyboard.
First, select which MODE you wish to play by using button n. 15. It is very important,
because the MODE establishes which manual the keyboard plays and which manual
the drawbars must control.
Second, select which manual you're going to play and/or to control, by using the
buttons n. 9 for the upper manual, button n. 12 for the lower manual, button n. 14 for
the pedalboard.
Now an example is given in order to explain how different modes work. Let's assume
that the upper manual is selected.
– MODE = SINGLE: the keyboard plays the upper manual and the drawbars
control the upper manual registration;
– MODE = SPLIT: the keyboard is split in two parts, the left part plays the lower
manual, the right part plays the upper manual; the drawbars control the upper
manual (which, in this example, is selected); if we select the lower manual, the
keyboard remains split but the drawbars will now control the lower manual;
– MODE = EXT. LOWER: the keyboard always controls the upper manual, the
drawbars will control the manual that is currently selected. This is because the
lower manual is expected to be played from an external MIDI keyboard.
The playable extension of the VB3 organ is 61 notes, from C (note 36) to C
(note 96). Applying the transposition would not affect the playable
extension, thus resulting in having mute notes at one of the extremes of the
keyboard.
CHORUS / VIBRATO
VB3 supports the 6 selections of Chorus or Vibrato, just like the original tonewheel
organs, and separate activation on the upper manual and/or the lower manual (that
also includes the pedalboard) by using only one button. When the upper manual is
selected, button n. 7 and its LED relate to the upper manual; when the lower manual
or the pedalboard is selected, button n. 7 works on the lower manual. Of course the
status (on or off ) is remembered. Shortcut: use button n. 7 along with the SHIFT button
to toggle the effect on the other manual.
CRUMAR MOJO 61 USER'S MANUAL - Page 13/32

DRAWBARS
We assume you already know what drawbars are and how they affect the sound of a
tonewheel organ. If you don't, we invite you to search the web and read one of many
documents that explain how tonewheel organs work. Our sole intention, in this
chapter, is to explain that the 9 drawbars can work for both the upper manual and
the lower manual, and the first 3 work for the pedalboard.
Have a look at figure 8. The row labeled “VB3” indicates the pitch of each drawbar; the
row labeled “TW-BASS” indicates that the first drawbar adjusts the 16' of the
pedalboard, the second drawbar adjusts the 8' and the third drawbar adjusts the
release time (simulation of the “string bass” function). Of course, in order to have
drawbars adjusting the pedalboard, you have to select the pedalboard by pushing
button n. 14. Don't forget, first make sure which manual you have selected, then move
the drawbars.
Despite the printed digits from 1 to 8 and the 15 “clicks” that you feel when
moving the drawbars, they actually send 128 MIDI values from 0 to 127.
Drawbars are just like normal slider pots, only with the shape and the look
of organ drawbars.
DRAWBAR PRESETS
Each manual (upper and lower) supports two “drawbar presets”; upper manual uses
buttons 8A and 8B, lower manual uses buttons 11A and 11B. They work just like the
reversed color keys of a console tonewheel organ, exactly the same way. They only
store the values of the drawbars. When a preset is activated, moving the drawbars
won't make any change to the sound; when a preset is activated on the upper
manual, the percussion is disabled; to re-enable the drawbars, just re-select the
manual you wish to control.
How to save a drawbar preset: select the desired manual, set the drawbars in the
desired position, press and hold the desired preset button. You'll see the LED quickly
blinking only once, indicating the end of the process.
CRUMAR MOJO 61 USER'S MANUAL - Page 14/32
Fig. 8 - Drawbar function table.

THE HOLD FUNCTION
Probably you've noticed that, next to the labels “Upper” and “Lower”, there's a smaller
label that reads “HOLD”. This is a special function that, when activated, momentarily
disconnects the drawbars from the sound, allowing you to adjust the drawbars
without affecting the sound, and get instantly to the new registration, as if it were a
stored preset, the exact moment you deactivate the HOLD function.
Example: select the upper manual, set the drawbars the way you like and play a
chord; now press the upper manual selection button again (button n. 9), you'll notice
that the corresponding LED starts flashing; now move the drawbars to a new
registration while still keeping the chord playing... hear, nothing changes to the
sound; now push the HOLD button again. The new registration is now playing.
This is pretty much what organists use to do with console organs that have two
drawbar sets per each manual.
PEDALS TO LOWER
To activate or deactivate this function, first press and hold the pedalboard selection
button n. 14 and then press lower selection button n. 12. The yellow LED n. 13 stays
on if this function is enabled. This function makes it possible to play the pedalboard
tones along with the lower manual, one stacked on top of the other, with the
difference that the lower manual will play across the whole keyboard, while the
pedalboard will only play across the lower 25 notes. To activate a split between the
pedalboard and the lower manual, keep the button n. 14 “PEDALS” depressed for two
seconds.
PERCUSSION
It's a short, percussive sound that's added on top of the
drawbar sound with the aim to reinforce the attack
transient, adds something special to the organ sound.
– Button n. 18: Turns the percussion on or off. Please
note that the percussion only works on the upper
manual and, when activated, disables the sound of the
last drawbar, exactly like in the original tonewheel
organ.
– Button n. 19: if activated, the percussion volume is “soft”; otherwise it's louder.
– Button n. 20: selects the percussion decay time, a short (fast) decay when it's
on, or a longer (slow) decay when it's off.
– Button n. 21: selects the harmonic used for the percussion sound, the third
harmonic (drawbar n. 5) when it's on, second harmonic (drawbar n. 4) when off.
CRUMAR MOJO 61 USER'S MANUAL - Page 15/32
Fig. 9 - The percussion buttons.

10. PLAYING THE PIPE ORGAN
Press the TYPE button n. 22 to shift to the next sound, the Pipe Organ. This is a one
manual organ with 9 stops, 3 couplers and the tremulant motor. One important thing:
remember to increase the Reverb level a bit when playing this sound!
The drawbars, in this case, will function as on/off switches, just like the “stops” of a
real pipe organ that can be pushed in (off ) or pulled out (on). The middle position is
the threshold, and the on/off transition is smooth. Every stop corresponds to a series
of different pipes, some pipes are reused on certain note ranges. Pipes are organized
differently across the stereo field, most generally the lower pitches are most audible
on the left channel, and the high pitches are located more towards the right channel.
The Pipe Organ also supports presets A and B as well as the HOLD function, just like
VB3. Please refer to the previous chapter.
COUPLERS
The same buttons that were previously used for the
percussion sound with VB3 are now used for the socalled “couplers”, which is a special mechanism of a
pipe organ that allows a single note to play on
multiple octaves.
Let's make an example: play the center C-note, now
push button n. 18, this will activate the “SUB OCTAVE”
coupler and you'll hear the lower C adding to the
sound; now push button n. 19 that will activate the
“OCTAVE” coupler, so that the higher C will also add
to the sound; lastly, button n. 20 enables the
“CANCEL UNISON” which will cancel the center note,
i.e. the note that you are actually playing, leaving only the lower C and the higher C.
If the “CANCEL UNISON” coupler is enabled and the other two are disabled,
you won't hear any sound. Actually, if you listen closely, you'll hear an airy
attack sound like air that blows through the key and doesn't reach the
pipes. Hey, it's physical modeling, after all!
TREMULANT MOTOR
This is an effect that can be activated using button n. 7. In pipe organs it's like a
rotating vent that produces a sort of tremolo effect by alternating the air flow
through the pipes.
CRUMAR MOJO 61 USER'S MANUAL - Page 16/32

Fig. 11 - Pipe organ couplers.

11. COMBO ORGANS
Back in the seventies many bands that could not afford an electro-magnetic
tonewheel organ used to buy smaller and less expensive transistor organs, mostly
made in Italy. Two of the most famous models are perfectly imitated by your Mojo 61.
Use the TYPE button n. 22 to activate the Combo organ sound. Deciding which
Combo organ is activated from the Type button is done via the Editor web-app or a
button shortcut explained later in this manual.
DRAWBARS
The row labeled “Combo F” refers to the “Compact DeLuxe” type. In this case, the
drawbars will act as on/off switches having the middle position as the threshold.
The row labeled “Combo V” refers to the “Continental” type. Here the drawbars act as
normal drawbars with one exception: the first 4 drawbars are the registers, the next
two adjust the volume of the two waveforms, the last three remain unused. If either
the 5th or the 6th drawbars are not pulled out, there will be no sound.
VIBRATO
The “Combo F” has 4 different vibrato types that can be selected
using button n. 6 and can be turned on or off using button n. 7.
The four selections are labeled as seen in fig. 13 and are:
– Light Slow
– Light Fast
– Heavy Slow
– Heavy Fast
The “Combo V” has no type selection, just the on-off switch.

12. ELECTRIC PIANO
Push the TYPE button n. 22 to activate the piano and start playing a little bit before
going on with the reading of this manual.
You will probably notice that playing the electric pianos of the Mojo 61 has a
particular vibe. These are not the usual samples that you've always found in all digital
keyboards since the early 80's, instead, this is a real-time synthesizer that instantly
reconstructs the sound of the electric piano while you play it, and you'll feel that it is
alive, it breathes, reacts to your playing, and behaves just like the real thing.
There are a few things that you can test to prove that we are right. First, the dynamic
response. Sampled instruments have a predetermined number of velocity layers.
Here the dynamic is practically infinite, you will hardly hear twice the same attacks.
The polyphony. The so-called ROMplers usually have a predetermined number of
voices that are cyclically assigned to the playing notes, and these are usually more
than the playing notes. The electric pianos in the Mojo 61 don't need to allocate
extra voices because they behave just like the real thing, there's one moving element
per key, so 88 playing keys = 88 voices (or 64 for the reed piano, 60 for the clavi
piano).
If you haven't connected a sustain pedal to your Mojo 61 we invite you do to so now.
Now put your foot on the sustain pedal and keep it depressed, then play a ribattuto
(keep playing the same note). You will notice some timbral changes due to the fact
that an element is vibrating (a tine or a reed) and the hammer continues to put it into
vibration, but sometimes the hammer happens to accelerate the vibration, other
times it happens to dampen it. Also the attack sound changes every time, because
you're virtually stimulating something that is already moving.
Resonances. An electric piano, just like an acoustic piano, has an harp and a
soundboard where metallic elements are put into vibration and, in turn, transmit
their vibration to the other elements. This is called “sympathetic” resonance. Try this:
play a note in the treble register (for example the last D), now push the sustain pedal
and keep playing that note. You will notice that all other tines (or reeds) are put into
vibration.
There is more, but we are confident that now you get the picture. Now back to the
boring technical stuff. Won't you miss the effects?
Switching between the four available piano engines is done from the Editor web-app
but can also be done using the preset buttons on the control panel. Shortcuts are
explained later in this manual.
CRUMAR MOJO 61 USER'S MANUAL - Page 18/32

13. APPLYING EFFECTS TO COMBO ORGANS AND ELECTRIC PIANOS
The Multi-function buttons numbered 18, 19, 20 and 21 can be used for accessing
the effects and other useful functions.
When playing a Combo Organ you can switch FX1 and FX2
by using respectively buttons n. 20 and n. 21. Choosing which
effect is associated to FX1 or to FX2 is done from the Editor
web-app but can also be done using a button shortcut
explained later.
When playing an electric piano, the octave can be shifted
down or up by using respectively button n. 18 or n. 19. These
buttons are exclusive, the octave can be either down or up. To
reset the octave simply depress the active button again.
The status of the effects is always remembered for
each of the two Combo Organs and each of the four Piano sounds.
Remembered settings include the on/off status of each effect along with all
their parameter settings made from the web-app editor. To make sure that
settings have been saved, press the active PRESET button again.
14. THE SHIFT BUTTON AND THE ALTERNATE FUNCTIONS
By pushing the SHIFT button n. 26 along with
buttons 18, 19, 20 and 21 it is possible to access to
other functions:
– SHIFT + button n. 18: transpose down by one
semitone. It is possible to get down to -12
semitones.
– SHIFT + button n. 19: transpose up by one
semitone. The higher limit is +12 semitones.
Note: When the transposition is active, the yellow LED
n. 23 is on.
– SHIFT + button n. 20: turns on or off the “Cabinet” simulation which, in case of
VB3, refers to the Rotary Speaker simulator, and in case of Combo Organs or
Electric Pianos, refers to the Static Amp simulator. When the Cabinet simulation
is on, it is possible to adjust the overdrive amount using knob n. 2.
– SHIFT + button n. 21: this toggles the “Local Off” function that disconnects the
keyboard from the internal sound generator and activates the alternative Tx
Midi Channel as explained later in this manual.

15. CONNECTING TO THE WEB-APP EDITOR
IMPORTANT: Accessing the internal editor web-app requires the Crumar Wi-Fi USB
dongle to be inserted into one of the two System USB ports located on the back of the
instrument. The dongle must be inserted when the instrument is off.
Any modern mobile device (tablets and smartphones) or any modern computer
(desktop or laptop) can be used to access the Editor web-app. The execution speed
of the Editor depends on the CPU power of your device. When the Mojo 61 is on, use
your device's network options to start scanning for existing Wi-Fi networks. The Mojo
61 should cast an SSID that starts with "Mojo-xxxxxxxx" where the "x" are replaced by
an hexadecimal serial number that is unique to each unit. Complete the connection
using the following password: 00000000 (eight times zero). The password can be
changed later from the home screen of the Editor app and can be restored to its
default value at any time by following the procedure described at page 11, point 4.
Once connected, open your favorite browser (Chrome, Safari, Firefox, Edge, etc.) and
type the URL using the IP number http://192.168.1.1
The Editor home page should load into your browser like a normal web site. This can
be viewed either in portrait or landscape mode, the page should redraw itself
accordingly. The Editor consists of an home page, four editing pages for the sound
parameters (VB3, Combo, Piano and Effects), one further page for editing the Midi CC
Map, and the button “SNAPSHOTS” that gives you access to the memory slots.
CRUMAR MOJO 61 USER'S MANUAL - Page 20/32

16. USING THE WEB-APP EDITOR
The Mojo 61 Editor is a Web-App, an interactive web site that can be used to adjust
all sound parameters and other functions. Parameters are generally presented under
the form of horizontal sliders for more convenience when using the app from a touch
device. However, the app can also be used with the mouse from a conventional
computer. An in-line help can be recalled by tapping on the question mark
icon on the top right corner, or on the parameter names in the editing pages.
THE HOME PAGE
Here is where you can set all global options and functions.
GLOBAL OPTIONS
– TUNING: This accepts a range from A=430 Hz to A=450 Hz,
with 440 Hz being the default value. Every time this setting
is changed, a reboot is required in order for the new
change to take effect.
– TX Channel: the MIDI channel used for sending messages
to the output ports. Considering that VB3 uses 3 channels,
if this is set to 1, the upper part will send on ch. 1, lower on
ch. 2 and the pedalboard will send on ch. 3. The channel
will be folded back if it exceeds 16, so if you set this to
channel 15, you'll have upper on 15, lower on 16 and
pedalboard on channel 1.
– Alt. Channel: this is the alternative Channel that can be used only when the
instrument is set in Local-off mode.
– TX Velocity: decide when to send the information of Note-on velocity, whether
always, never or according to the selected instrument (panel).
– CC Send: decide whether to send all Continuous Controller messages, only
those used by the pedals, or none of them (thus only note messages will be
sent).
– CC Presets: decide whether the CC messages related to the drawbars must be
sent or not when a drawbar preset is recalled.
– Sustain pedal: decide the function of the sustain pedal when in VB3 mode.
– Split note: set the lowest note of the right part of the keyboard when the Split
mode is used.
– Split octave: can shift the octave of the left part (lower manual) of the
keyboard when using the Split mode.
– Combo Organ: decide which Combo Organ you wish to use.
– Piano Model: decide which Piano model you wish to use.
VIEW MIDI CC MAP
Access the MIDI CC map. See the paragraph “MIDI MAP” later in this manual.
CRUMAR MOJO 61 USER'S MANUAL - Page 21/32

WI-FI PASSWORD
The default password for connecting to the Mojo 61 is "00000000", it can be changed
to any word of a max. length of 8 characters. It's preferable to use only letters and
numbers and avoid special characters. Setting a custom password prevents others to
connect to the Mojo 61 while we are performing on the stage. However, the Wi-Fi
radio in the Mojo 61 is powered enough to serve a connection in a range of max. 1 –
5 meters (15 feet) - even though this distance may vary according to possible
interferences - and accepts only one connection at a time, so there's no risk that two
devices are editing the Mojo 61 at the same time.
PAGE: EDIT VB3
This page shows all parameters related to the VB3 engine and the Rotary Speaker
effect. Every time you scroll a fader left or right, you can read the current value on
top of it.
PAGE: EDIT COMBO
This page shows all parameters related to the two Combo Organ simulations.
PAGE: EDIT PIANO
This page shows all parameters related to the two electric piano simulations.
PAGE: EDIT EFFECTS
This page shows the parameters related to the effects that can be used with the
Combo Organs and the Electric Pianos. Effects are organized in colored boxes.
PAGE: MIDI MAP
The MIDI Map page can be reached from the button in the home page or by
clicking/tapping on the MIDI CC assigned to each parameter. It is possible to assign
any of the 127 CC numbers to any parameter, and more than one parameter can be
assigned to the same CC, if necessary, but this means that when that specific CC
number is received, all parameters assigned to it will change accordingly.
BUTTON: SNAPSHOTS
Click or tap this button in order to store or recall one of the eight available snapshots.

17. BRIEF EXPLANATION OF ALL ORGAN PARAMETERS
– Generator: select a tonewheel generator from this list. Each generator is based
on actual values as measured from real console organs of the B/C/A series.
– Generator Shape: select between OFF (no shaping) or 3 levels of CUT and 3
levels of BOOST. These will modify the amplitude chart of the generator values
according to different positions along the generator. This parameter does not
apply any equalization to the sound. Levels 1 can boost or cut starting from
wheel n. 25; levels 2 start from wheel n. 52; levels 3 start from wheel n. 72.
– Leakage: adjusts the background hum & hiss.
– Crosstalk: adjusts the amount of crosstalk caused by the analog circuitry. This
is a very important element of the tonewheel organ sound.
– Xtalk Shape: since the crosstalk consists of both bass and treble tones, this
parameter mixes between the presence of one or the other, left towards a
“rumble” noise, right towards a “brilliant” noise.
– Complex wheels: are special tonewheels only used for the first 12 tones wired
with the pedalboard. Unselecting this parameter will use standard sinus
tonewheels.
– Foldback on 16': the first 16 wheels wired to the keyboards are usually folded
back, thus starting from wheel n.13 rather than from wheel n.1. If you wish to
use the first 12 wheels on the manuals, uncheck this option but you should also
uncheck the Complex wheels.
– Resistor wires: are the small wires that in the vintage organ connect the
keyboards to the generator. This parameter offers three different values:
“Console: NEW”, as specified by the original B3 specifications; “Console: OLD”,
resulting in a more present low-end; “Spinet”, same as “Console NEW” but
without the foldback.
– Drawbar trims: the 9 slider below this section can be used to adjust the
presence of each drawbar. This will apply above the actual drawbar
registrations for both the upper and the lower manual.
– Percussion settings: set the parameters of the percussion circuit such as the
level when it's on normal or soft, the decay time when it's on slow or fast, the
overall level, and the loudness loss when the volume tab is set to normal.
– Perc Paradise Mod: this is a “hack” that causes the percussion to never decay.
What's special in this is that if you activate the scanner vibrato effect, you'll
notice that the vibrato is applied to the rest of the drawbars but not to the
percussion tone.
– Other settings: here you can adjust the depth of the vibrato circuit and the mix
amount that affects the chorus settings, plus some parameters related to the
generation of the KeyClick noise. Read the tool-tips for more details.
– Preamp Bass / Treble: adjust the frequency response of the organ's built-in
preamp circuitry.
CRUMAR MOJO 61 USER'S MANUAL - Page 23/32

Parameters for the Rotary speaker are:
– Horn slow / fast: adjust the speed offset of the horn for when the speed is on
slow or on fast.
– Bass slow / fast: same as above but for the bass rotor.
– Horn up / down: adjust the acceleration and deceleration times of the horn for
the transitions between the slow and fast speeds. When the brake is engaged,
the power is taken off from the motor so the horn slows down until stopping
only driven by the centrifugal force, so the time between fast and stop may be
longer than from fast to slow.
– Bass up / down: same as above but for the bass rotor.
– Balance: adjusts the balance between the horn and the bass rotor.
– Ambience: a real amplifier stays in a real environment causing the
microphones to capture the sound reflections as well as the direct sound
coming from the speakers. This parameter adjusts the amount of
environmental reflections.
– Cabinet: adjusts the amount of resonances caused by the wooden cabinet.
– Mic Angle: adjusts the angle between the two microphones at the horn,
ranging from 0 (both microphones in the same spot) to 180 degrees
(microphones at the opposite sides of the cabinets). This simulation considers
only three microphones, two for the horn and one for the bass rotor.
– Mic Distance: adjusts the distance between the microphones and the cabinet.
A longer distance results in more sound dispersion, a shorter distance results in
a deeper proximity effect.
– Horn EQ: not all vintage rotary speakers have the same quality for what
concerns the sound coming from the horn, some are brighter, some are duller
or maybe just well balanced. This parameter lets you adjust the treble response
of the horn sound.
– Mid reflections: adjusts the amount of sound reflections happening in the
middle of the stereo field.
– Doppler intensity: the so called “Doppler” effect is the fundamental of the
“Leslie” effect that causes the sound to be cyclically untuned while the sound
source (the speaker) gets farther or nearer to the listened; this parameter lets
you adjust the amount of this effect that is mostly caused by the sound
reflections over the walls around the amplifier.
CRUMAR MOJO 61 USER'S MANUAL - Page 24/32

– Dry Leak: some of the dry sound coming from the speakers does not reach the
rotating elements and is mixed with the rotating sound. Use this parameter to
adjust the amount of dry signal you want to be mixed in.
– Bass Port: a real Leslie cabinet has a hole in the back that serves for two
reasons: 1) lets the heat from the motors ventilate out from the cabinet and 2)
acts as a bass tuning port, like those found on modern speakers. If you put a
microphone in front of this hole you get nothing but sub-bass frequencies. Use
this parameter to adjust the amount of sub-bass you want to get into the mix.
– Tube feedback. This is a very important parameter that works on an aspect of
the whole amplification system that can drastically vary both the dynamic
response and the frequency response, as well as have an impact on the
overdrive. When a Leslie cabinet is set very close to the Hammond organ and is
played at a high volume, there's some sort of feedback between the tubes, the
transformers and the pickups of the Hammond and the speakers of the Leslie,
resulting in a sound that tends to get “fatter”, the attack is “punchier” and the
distortion is aggressive, giving you the feeling that some sort of energy is
looping between the organ and its amplifier. Now, a genuine Leslie 122 or 147
is only 40W of power, but if you try to connect your Hammond organ to a 100W
guitar amp such as a Marshall JCM900 or a Fender Twin you'll notice that the
amp starts going in feedback even if you don't play any note on the organ. This
is... pure analog power! Try this parameter at small steps, it can drastically
change the sound in both a pleasant or unpleasant way, according to your
tastes.
– Stop Position: you can use this parameter to find a position where the horn
and rotor should “preferably” stop when you set the speed lever in the brake
position and the “Front Stop” option is enabled. Please consider that not always
the position you've set is reached with precision, it depends mostly on the
Ramp Down times you've set... after all it's virtual reality, baby! It takes into
account the kinetic energy, the gravity, the belt friction...
– Noises: well, a real rotary effect is far from being a silent amplifier. Your
microphones will pick up not only the sound but also the wind generated by
the rotating elements, and the relays that switch between the fast and slow
motors. Use this parameter to adjust the amount of noises you want to get into
the mix.
– Memphis Style: check this parameter to unplug the motors that drive the bass
rotor. This way, the bass stays motionless while the horns keep spinning.
– Front Stop: this very sought after function causes the horn and the bass rotor
to stop always in a “sweet” spot every time the brake is engaged. VB3-II uses a
simple algorithm that produces this effect in a very pleasant and seamless way
that you won't even notice when you're braking the rotors.
CRUMAR MOJO 61 USER'S MANUAL - Page 25/32

Notes on the rotation speeds.
All sliders in the edit pages, whenever moved, displays the readout in either MIDI or
actual value, when available. As for the Rotary speaker's rotation speeds and times,
values are shown in Hz and Seconds. To convert Hz to RPM (revolutions per minute),
just multiply the Hz value by 60. For example, the horn, when the Horn Slow
parameter is set at 64, rotates at 0,77 Hz which translates in 46,2 RPM. All the speed
values can be varied between 50% and 150% of the center value. The ramp up and
ramp down times are in seconds, and can be varied between 50% and 500% of the
center value.
Center values are:
– Horn slow: 0,77 Hz 46,2 RPM→
– Horn fast: 6,9 Hz 414 RPM→
– Bass slow: 0,72 Hz 43,2 RPM→
– Bass fast: 6,4 Hz 384 RPM→
– Horn ramp up: 1 second
– Horn ramp down: 0,8 seconds
– Bass ramp up: 6 seconds
– Bass ramp down: 3,5 seconds
These times are average values as measured by a wide sample of well working and
serviced vintage Leslie 122, 142, 147 and 145 models.
Due to kinetics energy, when the Rotors ramp down from fast to brake and the Front
Stop option is disabled, they take a bit longer to get to full stop position.
CRUMAR MOJO 61 USER'S MANUAL - Page 26/32

18. SHORTCUTS
Some of the functions that are normally accessed from the Editor web-app can also
be accessed using key-combinations on the command panel. Here's a summary:
– Switch between the two Combo Organ sounds: use UPPER PRESET A for
Combo Type “F” and UPPER PRESET B for Combo Type “V”.
– Switch between the four Piano sounds: use UPPER PRESET A for Tine Piano and
UPPER PRESET B for Reed Piano; use LOWER PRESET A for Clavi Piano and
LOWER PRESET B for Acoustic Piano.
– Switch between Square, Triangle and Mono Tremolo: press & hold the multi-
function button n. 20 labeled “FX1”, the effect turns off for a short while then
turns on again with the new setting.
– Switch between Phaser and Chorus: press & hold the multi-function button n.
21 labeled “FX2”, the effect turns off for a short while then turns on again with
the new setting.
– Set the split point: press SHIFT + MODE button n. 15, the Split LED starts
blinking, now play the desired split note on the keyboard (you won't hear any
sound), the LED restores its previous position and the split point is now set and
saved.
– Reset the transposition: press SHIFT + press & hold either button n. 18 or n. 19,
the transpose LED n. 23 should turn off and the transpose amount is now
zeroed.
– When playing VB3, it is possible to toggle the Chorus/Vibrato effect on the
other manual by pressing SHIFT + button n. 7, i.e. if the upper manual is
selected, using this shortcut, the effect is toggled on the lower manual.
CRUMAR MOJO 61 USER'S MANUAL - Page 27/32

19. THE USB PORTS
The Mojo 61 includes 2 Type-A “host” USB 2.0 ports. These
are mainly used for updating the software or for
accepting external accessories.
An interesting use for a USB system port is the possibility
to connect a “Class-compliant USB-MIDI device”, i.e. one of
the many MIDI devices that don't need special drivers
when they are connected to a conventional computer. The Mojo 61 will recognize
USB-MIDI devices and will use them along with any other MIDI equipment
connected to either one or both the classic MIDI inputs located on the rear panel.
This way you can connect up to 3 MIDI devices that send messages to the Mojo 61,
for example a keyboard, a pedalboard and a control surface.
Please avoid connecting unsupported devices to this port. Please note that this port can
supply a max of 250 mA of current. Don't use this port to charge mobile devices.
Original CRUMAR accessories that can be connected to the SYSTEM USB ports:
– Original USB Wi-Fi dongle for accessing the web-app editor
– Mojopedals 2018
– G.M.LAB D9U – d-i-y drawbar controller
– G.M.LAB D9X – d-i-y drawbar controller with extended features
– G.M.LAB MJU – d-i-y Midi Jack USB
An additional Type-B USB 2.0 port is present at the back side of the
Mojo 61 that provides Class-compliant USB-MIDI IN/OUT
connection to your computer. Use this port to connect the Mojo
61 to your computer software. No drivers are needed for Windows,
OS X and Linux.
OFFLINE USB EDITOR
Starting from firmware version 1.34 it's possible to access an off-line editor (in the
sense that it doesn't require a network wi-fi connection to the Mojo 61) by
connecting the Mojo 61 to a computer using the MIDI-USB port, and accessing a
website from a Chrome, Opera or Firefox browser (Mozilla may require add-ons).
Connect your Mojo 61 to your computer or Android device, open the browser and
navigate to the URL:

CRUMAR MOJO 61 USER'S MANUAL - Page 28/32

20. MIDI FUNCTIONS AND IMPLEMENTATION CHART
Mojo 61 has a very functional and complete MIDI implementation. It can send and
receive messages related to each single control and each single parameter; all
physical controls located on the control panel have fixed MIDI CC assignments, while
all sound parameters accessible from the Editor web-app can be freely assigned by
the user. Every time a CC value is received, if it affects something that should be
visible on the panel via LEDs, these turn on or off accordingly.

KEYBOARD VELOCITY
Mojo 61 can send notes with or without velocity according to the instrument
selected with the Type button n. 22. If VB3 or Combo Organ is selected, notes are
sent with a fixed velocity value of 127 but the first key contact is used (fast key
triggering). If Pipe Organ or EP is selected, velocity is sent. Key-off velocity is always
sent. Any transposition or octave shifting applied to the internal sound generator is
also applied to the transmitted note messages.
PEDALS
The sustain pedal always sends CC #64 with values 0 or 127 when the EP is selected.
To send CC #64 also in VB3 mode, this must be activated from the Global Options in
the Editor's home page. The expression (Swell) pedal sends CC #11.
OTHER
The instrument type selection can be remotely done by sending Program Change
events with the following values: 0 = VB3, 1 = Pipe Organ, 2 = Combo “F”, 3 = Combo
“V”, 4 = Tine Piano, 5 = Reed Piano, 6 = Clavi Piano, 7 = Acoustic Piano.
