 - add FLAC as export-format?
 
 Andrew Kelley's todo:
-- pencil tool icon doesn't set right. selection arrow cursor doesn't set right
 - add a Modulator class and a Humanizer tool to the piano roll
-- global playback buttons, like in FL Studio
-- when you add VSTi, have it automatically pop the find VST plugin dialog
-- make pitch bend range adjustable
-- monophonic mode on 3xosc
-- add dithering
-- add global playback mode to .mmp file format
 - when a song goes past the end of the song, make it stop or loop
-- allow increasing the width of song editor things, it will make the BB repeat
 - when looking at a piano roll, if the song is playing that pattern, move the position ticker to where it should be
-- multiview button - show notes from every instrument in the current beat+bassline with different colors
-- undo/redo for piano roll
 - add a tools menu to piano roll
   * put some of the tools on there that already have keyboard shortcuts (ctrl+up/down, shift+left/right)
   * humanizing tool
   * quick slice
   * look through FL Studio's tools and implement some of them
-- slice tool for piano roll
+- slice tool for piano roll, "map audio files to piano roll keys"
 - when a note is played, show the note as being depressed in the piano roll

@@ -89,5 +89,5 @@ Andrew Kelley's todo:
 - the 'add beat+bassline' button in the beat+bassline editor is misleading - I say we remove it and rely on the song editor to add beat+basslines
 - make it so that 3xosc notes don't max out
 - copy-pasted automation patterns have to be manually linked back to their knob for some reason
-- fix memory leaks
 - cloning a pattern in the song editor should copy automation tracks along with notes
