PPG - Polyphonic Pressure Generator for Voltage Modular (Hardware Demo)

video upload by Cherry Audio

"This is a quick demonstration of the Polyphonic Pressure Generator from @Tim Shoebridge of Soundmangling.com for Voltage Modular. Voltage Modular is generally regarded as a software modular system, but Tim has been creating some fantastic modules that extend it to hardware. VM runs standalone or in a DAW, and with the PPG module and a regular keyboard controller, you have all you need to transmit polyphonic aftertouch messages to Poly AT compatible synthesizers, hardware or software.

In monophonic channel aftertouch, applying pressure to any key within a chord will apply modulation to all notes currently held. With polyphonic aftertouch, modulation can be applied on a per-note basis, allowing for more expressive performances.

In this demo, the Roland JUPITER-X has a keybed that provides basic monophonic channel pressure aftertouch. But the synth engine itself actually supports receipt of polyphonic aftertouch messages and plays them accordingly. Usually, this would require an external controller like a CME XKey or the Hydrasynth to exploit the Poly AT of the JUPITER-X (or Xm).

PPG can be used to create the same expressive experience with any standard controller, and any synth that receives Poly AT (like Sequential's Prophet 6 and OB-6). This brief demo shows the difference between channel pressure on the JUPITER-X, and then polyphonic aftertouch with PPG and a simple Launchkey Mini. In this case, PPG is configured with a velocity threshold so that any notes played at or above a certain velocity get the modulation envelope applied to them. The other notes are unaffected.
