NOTES ABOUT THIS MANUAL

This manual can be considered a live document, as it may be updated in future
according to possible changes introduced in new firmware updates. We recommend
to keep an eye at the support section of the Crumar website and check for new
versions of both the manual and the instrument's firmware.

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 explanation 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 can have an instant feedback of the
notions here explained.

1. THE SOUND OF MOJO

VB3-II virtual tonewheel organ

The sound of Crumar Mojo is based on the same “core” of the virtual
instrument GSi VB3-II. While the virtual instrument runs on regular
computers, Mojo is built on a new dedicated DSP platform,
purposedly designed by Crumar for the new Mojo line. This means
that with Mojo not only you have access to a familiar and intuitive

organ interface controlling one of the most realistic tonewheel organ
simulations, but you also have access to a detailed and extensive parameter set that
lets you customize the organ sound in order to match your preferences any way you
like.

2. THE COMMAND PANEL

In this chapter we explore the command panel of the Mojo. Most of the controls on
the panel are familiar to veterans of the tonewheel organs. If you fit that category,
you've probably already recognized the drawbars, upper on the left, lower on the
right, pedalboard in the middle; then the controls for the “Vibrato Scanner”, the four
tablet switches for the percussion, and you've also noticed that everything is right
where it belongs.

2.1 – LEFT SIDE KNOBS

On the left side you find the 3 knobs: volume overdrive and reverb. Having these
three on the left side is kind of tactical, so you can keep playing with your right hand
while adjusting the three most important parameters before starting your
performance.

2.2 - VIBRATO/CHORUS

The Vibrato/Chorus controls, which belong to this side of the console, are presented
exactly like on a vintage tonewheel organ. There are two large buttons for turning
the effect on or off on the upper or on the lower manual independently, and a large
knob that lets you choose the type of effect to use between the 6 possible
combinations: V1, C1, V2, C2, V3, C3 whereas the 'V' produce just a vibrato effect and
the 'C' produce a chorus effect. In the Mojo the selector is a rotary encoder with 6
LEDs that indicate the current selection.

PLEASE NOTE: As opposed to mechanical “rocket” switches, these are push-push yellow
illuminated buttons, about the size of the vintage tablet switches, that work exactly the
same way. You can hit them in any point to activate them, no need to reach for the exact
middle point. Furthermore, when the C/V effect is turned on for the lower manual, it's also
applied to the pedalboard tones.
