I've never been able to grok LiSa -- the doc and examples leave me confused. Maybe could someone write up an example that demonstrates the basic Echoplex use case? Record from dac On start event, start recording On stop event, loop recording and pass through dac On overdub event, loop recording and start recording another loop from dac michael

I've always used the comments at the end of the file examples/special/readme-LiSa2.ck as an LiSa Ugen API reference, although I think that there are still many undocumented "features" of LiSa.

We lack a example like that? That's a issue, imho. We need something like that in the examples dir; it'd be useful and aside from the literal working demonstrate a example of how we can integrate ChucK in (electro) acoustical setups.

I'll make one this week, remind me if I slack on this. I "need" one anyway as I've been meaning to get into the electric guitar that I got out of a bass-player's trash when he was moving :-)

Yours, Kas.

I've use ChucK a lot for recording my guitar and then do stuff with it, controlled by a Roland PK-5A (an organ-style pedal MIDI controller). It works great! Ive used LiSa for this. If working with organ bass pedals feels strange I've heard good stuff about the Behringer FCB1010.

My view is that you don't need anything besides ChucK to get this to work - in fact, other stuff would only get in the way. But that's just me. (Granted I've done this sort of thing on the NMG2 as well, but I didn't mix it with ChucK - I use one instrument at a time).

For particular issues with LiSa or other things, do a post and quite probably me or someone else can help out (I think electro-music.com is better for that kind of stuff, though this mailing list also works I guess). One thing I struggled with (possibly only a problem on the MOTU units) was getting the right input in to ChucK.

I will make the argument that it would be difficult to implement all of what you wish to do in ChucK directly, rather you will most likely end up with a hodge-podge of software tied together by JACK (or a similar audio routing tech) and MIDI and/or OSC for control change communication.

Aside from how any non-trivial code demands that we consider structure, and how creating a instrument means thinking hard about our own artistic perspectives (both of which are hard, even if good end-results typically look like it's easy) I don't really see what would be very difficult here for ChucK as a system. I feel everything mentioned *should* be possible so if there turn out to be real issues we might need to look at them together and see what the issue is. As I see it the hardest part here will likely be the interface. "real" loopers are so nice partially because they are so simple. That presents real challenges for a "advanced looper". Maybe you for see other issues? Yours, Kas.
