Muting, unmuting-- indicator Mute buttons
You mute an instrument in the Rack view. When you open the Sequencer or Mixer window you go crazy: Why is there no sound? You mute a track in the Sequencer view and go to the Mixer. One of those tracks is silent, but none of the Mute buttons is lit. This is a bug, a miss, a programming error. This is a source of frustration, this is evidence that something has not been thought through properly. There is no logic in disregarding our need for control, especially in the creative process.
Please fix this on Reason 7.
