Right, I would agree.

SooperLooper works well on its own for interactive use, with e.g. a
guitar and MIDI foot pedal.  When I'm trying to play along to a song
driven by ChucK, the whole setup becomes a royal mess, MIDI/OSC sync,
mixing audio streams via jack, etc. etc.

The interface I'm looking for is an API within ChucK with just those
four methods, record/overdub/undo/redo.  That way I can just use
ChucK's internal timing, run the looper programatically, and keep all
the audio within ChucK.

So I've heard.  ;)

Thanks, I will peruse those examples again.

Hmm, yes, those would be the devil(s) in the details.
