Hi Sean: A few questions re: your excellent WhySynth : Can I get multiple instances, each with its own GUI ? WS seems weird wrt MIDI program change. Am I missing something ? Sending a change from a sequencer or keyboard doesn't match the default list of voices. PC 0 selects a sound all right, but it's not the Slow Strings at position 0 in the default patch list. What is MIDI PC actually selecting ? Edits made to a patch don't take effect in realtime, or am I missing something again ? Any chance of a multitimbral version ? I want to create a short demo based on original patches, using only WS for all the sounds except the drums. So I'll need either multiple instances or multitimbral capability, or I'll have to sync multiple tracks. Any other suggestions ? Best, dp
