PARAMETER OVERVIEW
Rate •
The RATE knob affects the rate or speed of the selected LFO. You can adjust the rate continuously from
0-127, or you can use it to select clock divisions by first enabling Clock mode in the EDIT menu.
Please select patch ROM B-123 ‘Tutorial 4’ before continuing
Matrix Section
The Modulation Matrix is a very powerful tool for adding movement and dynamics to a sound. It comprises 6
main slots, each of which can ‘patch’ a control source into 3 different parameters. This means you can have
up to 18 different modulations happening all at once (not including those already assigned to the LFOs and
Envelopes!) in a virtually unlimited number of configurations. Creative use of the Mod Matrix can make the
difference between an average patch and something truly spectacular!
Mod Select •
Press the MOD SELECT button repeatedly to move the focus of the VALUE knobs through Slots 1-6. Once
you have selected the Slot, use the VALUE knobs as follows:
Soft Knob Parameter Meaning
#1 Source Select the source of the modulation, i.e. Mod Wheel, Velocity, LFOs etc
#2 Amount Determine the depth of modulation - set either a positive or negative value
#3 Destination Select the parameter to be modulated
Once a parameter is highlighted, you can use the VALUE buttons for fine adjustments.
The SLOT 1-6 LEDs illuminate once their respective Slot has been assigned a Source and a Destination, so
you can easily see which ones are active.
Destination •
Use the DESTINATION up/down buttons to move the focus of the VALUE knobs through each of the 3 rout-
ings within each Slot. If you continue to press the same direction, you will move on to the next Slot. You can
also use the PARAMETER buttons to do this, if you prefer.
Note that the VALUE knobs are always focussed collectively on one row at a time.
Take a look at all the modulation routings used in patch ‘Tutorial 4’. It uses a combination of realtime control-
lers like MIDI Note On Velocity and the Modulation Wheel, as well as assigning LFOs and the Filter Envelope
to modulate different parameters. Experimenting with different Amount values for each should help to give
you an idea of how powerful the Modulation Matrix is.
