-// make a midi learn struct/button
-// use it to make a few midi triggers:
-// - mute out
-// - mute in
-// - mute both
-// all mutes with choice between latch and toggle
-// - reset pattern
-// - momentary mode:
-//   in this mode, the taps are only heard until the key is released
-//   the counter starts when the note for this trigger is pressed
-// - stop listening for taps (so it can be used in a daw on an instrument track)
-//
-// add adsr envelopes
+// - make a midi learn struct/button
+//   the button is a custom view, that either displays the learned note, or the word "learning"
+//   it knows which via is_learning learning_index and learned_notes
+//   its color changes when that note is pressed
+//   - use it to make a few midi triggers:
+//     - mute out
+//     - mute in (fake it by recording the timing and muting the out a bit later)
+//     - mute both
