Refactoring with granulator in a quark

NOTES.md

@@ -6,6 +6,16 @@
 - multiple grain buffers - TouchOsc interface to select which to send to
 - play back all buffers?
 
+- refactor for multitrack
+  - which controls are per-track and which are global? sort these out in the UI
+  - encapsulate a grainstrack in an object?
+
+- auto-mix: base the mix level on how loud the incoming signal is so that tracks don't fade out
+
+- fancier playback:
+  - intertwine different rates and directions
+
+
 - rhythm controls
   - number of steps in step granulator
   - modulate grain level in time with playback
