Multi-patches are quick to program. The second public demonstration of the Soundplane used a Matrix-12. I = dialed in the Soundplane to detect 10 touches, and assigned those to 10 = MIDI channels on the Matrix-12 so that each finger had its own pitch = bend, channel pressure, and modulation lever control. Unfortunately, = people kept walking up to the table and trying to play the Matrix-12 = from its keyboard instead of from the multi-touch pressure sensitive = controller in front of it. So, I quickly assigned the remaining two = voices to the keyboard in a duophonic voice allocation. It was super = easy to set up. You couldn=E2=80=99t play chords from the keyboard that = way, but the point was to play chords on the Soundplane and have = three-dimensional control of every note. The hard part was finding appropriate sounds and then modifying the = voice settings to track pressure continuously, rather than just run = through an envelope at a fixed rate. The voice architecture has a = dual-VCA signal path at the output of each voice, so it was fairly easy = to connect pressure to one of those. What was more difficult was taming = the existing VCA envelope so that it didn=E2=80=99t totally shut down = the voice while you were still touching the controller. The voice = editing appears direct, but the complexity is deep enough that it=E2=80=99= s not necessarily quick. The Matrix-12 does have a Modulation page = that=E2=80=99s missing from the Xpander, and I find this helps browse = through the settings in a voice patch. A graphical editor would help if = you don=E2=80=99t mind a computer attached via MIDI.
