Three instances are launched, the first has Channel 0 in its window titlebar, the next has Channel 1, the last has Channel 2. However, only Channel 0 is accessable from my sequencer. What's going on ? The channels referred to are MIDI channels, yes ? How can I reach the other instances ? Btw, a MIDI activity light would be a nice addition to WhySynth. :) Best, dp
