This video, via Eigenharpist Geert Bevin, demonstrates a new capability that is under development for WolfGang Palm’s PPG WaveGenerator – voice-per-channel MIDI expression.
Here’s what Bevin has to say about it:
I’ve been helping Wolfgang Palm with adding a new feature to PPG Wavegenerator that allows per-note expression over MIDI, by implementing a voice-per-channel MIDI mode. This is a quick test of the first fully working version he sent me today. It’s short, but I hope it shows the possibilities of this feature with new electronic instruments like the Eigenharp.
Note that this demo is only using one single sound that has independent expression in three axis for each individual note.
I’m using a modified version of the standard ‘Jigsaw Lead’ patch that has up-down movement mapped to per-note filter cutoff (Y movement in PPG), pressure (X movement in PPG) to note volume and left-right movement to per-note pitch with a 5 semitone interval.
At this point, this is a sneak preview of an unreleased feature. But apps like PPG WaveGenerator could make polyphonic synth expression, something that’s largely been limited to rare and expensive synths, into a relatively inexpensive option.
