realtime sample, playback, overdub, erase, etc,.. somewhat inspired by repeatler, but have plans for some other directions and features.

beats: buffersize, in beats
draw mode: how to draw the waveform. off, dots, lines.
sync mode: manual = play state manually toggled on/off with 'transport note' (below) manual, seq = sync to sequencer (reaper)
transport note: midi note to toggle transport on/off (if syncmode=manual)
record note: switch to record mode. records incoming audio into buffer
play note: switch to play mode. playback from buffer
erase note: ...and same, but erase/clear buffer
bypass note: bypass mode

the record/play/erase/bypass modes are exclusive states (can only be in one of these modes), indicated by cursor color: red=record, green=play, blue=erase, white=bypass.
