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.

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.

2. THE EFFECTS
Tremolo / Auto-panner / Ring modulator
Mojo 61 offers electric pianos and organs, so how could we miss such an important
effect in the chain? It is a must in mono mode when combined with the Reed EP,
sounds great in square stereo with the Tines EP.
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.

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.
