About General Purpose Modulation

Although there are several dedicated modulators in the QS (e.g., the pitch can always
be modulated by the pitch LFO and Pitch Envelope), sophisticated synthesizer
programming demands the ability to use as many modulation sources as possible to
modulate as many modulation destinations as desired.
The QS arranges its modulation source outputs and modulation destination inputs
into a “matrix” so that any selected source can connect to any of several destinations.
There are six general purpose matrix modulators, which allows you to control up to
six parameters with any of several control sources.
Use the MOD functions to setup your own customized control of a program, such as:
• Using the PEDAL 1 input or the Controller A Slider to control volume, brightness
(filter cutoff), effect level, LFO speed, etc.
• Using velocity to increase or decrease the attack speed of an envelope, so playing
softly makes the sound fade in, while playing hard causes an immediate attack.
• Using release velocity to increase/decrease the release time of an envelope, so
quick releases of the keys cut off the end of the sound, while slow key releases
allow the sound to fade away gradually.
The MOD functions give you the freedom to go beyond the standard modulation
sources built-in to other functions.
Note: Six Mods may seem like a lot, but once you run out, you're going to wish you
had more! One way to extend the power of your Mod section is to be sure you're not
routing something with a Mod that could be handled elsewhere in the QS's functions.
Here's a list of routings which we "hardwired" into the synth to free up Mods:
