TNT has shared a MIDI SysEX Controller for the Access Virus Indigo Synth. The control template layout works for TouchOSC.
This are Templates for TouchOsc and TNT has tested the Layouts with Virus Indigo (OS 4.9).
Virus-Arpeggio-Multi.touchosc“ and „Virus-Arpeggio-Single.touchosc“ was made for OS 4.5 Version and supports only 40 Pattern. I think it should be enough for your creativity. Virus-Mod-Matrix-Ch01.touchosc“ and „Virus-Mod-Matrix-Ch09“ are self explanatory.
