I had tried different versions of chuck, first I used versions
available for debian or ubuntu (currently it is 126.96.36.199.dfsg-1.3+b1),
then I compiled from the released sources and then I compiled from the
My tests were at different stages, so they don't necessarily fit
together, so my conclusions may have been wrong.
When I tried multiple LiSa's I got an error message on creation.
Today I tried my old chuck file again and it works (using chuck 188.8.131.52).
Thanks for pushing me to try again..
At first I had also a confusion about LiSa's voices, which I thought
were like channels, but they seem to be for playing the same samples
in a different way.

here you mean saving stereo sound to a single file, right?
However, it would be ok for me to save a stereo sound to two files.
How would you do this, once you have recorded into n LiSa buffers?

data processing is ok for me, but I have to explore interfacing to
jack/alsa/midi/osc and the hard realtime processing is also new to me.
For me, using chuck simplifies exactly this. I then don't have to
bother with those "details". Also chuck allows a higher level of
Yesterday I made a big step in c/c++ jack programming.
I see projects, where chuck might be too slow and I'll need to use c++
(or googles golang?) instead.
For most things chuck would fit very well, if some simple things can be done.

I did many test and always there was one thing missing...
Then I tried to dig into chuck source code and took the easiest thing
I could manage at this knowledge level.
Also LiSa has many features, I don't really need or don't need them
the way they are implemented.
It was not very difficult to allow a SndBuf to record.
Then I tried to allow it to do multichannel which I thought would be
easy, too. But I failed managing the buffer.
For my looper project I need some special things, for which I don't
have a solution yet.
When I have time (not now because I'm at work), I can describe what I
want to do.

I used this:
cvs -d :ext:anon-chuck at cvs.cs.princeton.edu:/cvs checkout chuck_dev
