 # TODO
 
-## Granulator
+- quantise playback speed to rational values
+- display the playback and harmonics when quantised
 
-Fix chorus and detune - why isn't it being triggered?
+- multiple grain buffers - TouchOsc interface to select which to send to
+- play back all buffers?
 
-Add pitch shifting
-
-Change harmonics for chorus
-
-Lock harmonics to octaves / ratios
-
-## Effects chain
-
-Add an effects chain like with midilooper
-
--> filter -> reverb -> out
+- rhythm controls
+  - number of steps in step granulator
+  - modulate grain level in time with playback
+  - sync LFOs to playback
 
 
-
-## LFO mod
-
-Add the new-style lfo mods to filter
-
-## More LFO mods
-
-Allow other settings to be modulated
-
-## Input filter
-
-Switch in and out a single input filter like distort, peak FFT, etc,
