Extended Keyboard Techniques: Aftertouch | 13

Keeping the patch as we have it, let’s now use aftertouch to modulate the delay. Take
the KB AT OUT and patch it to the TIME 1 IN of the STEREO DELAY.
Increase the MIX knob in the STEREO DELAY section to noon and add a bit of feedback
with the FEEDBACK knob. Play around, and you’ll notice that now as you apply
aftertouch you lengthen the delay time—resulting in some wonderfully wobbly sounds.

We still have an attenuator handy, which we can use to invert the aftertouch voltage if
we like. Patch KB AT OUT to the remaining ATTENUATOR input, set the ATTENUATOR
knob counter-clockwise to invert the incoming voltage, and patch the output to TIME
1 IN in the STEREO DELAY. This will make it so that applying aftertouch shortens the
delay time rather than lengthens it.
In fact, with this attenuator we have control of both the range of modulation for
aftertouch and its direction—such is the power of the inverting attenuators of Matriarch!
