Question My VoicePrism changes presets when I change presets on my keyboard. I don´t want this to happen as I want to have independent control over my VoicePrism and it should not switch together with the keyboard program change. What can I do to filter out the program change

From VoicePrism software version 1.03, a Midi filter has been incorporated in the software. You need to access the Utility menu, and navigate to the MIDI page. Here you can set the MIDI filter to filter out, Program Change or Sysex data, or both. This should solve the problem.
