Ogg: Re: [Csnd] Csound 6 - Live Coding Demo

For what it's worth: A trick often used in some livecoding environments (Impromptu, Fluxus, Extempore) is 'temporal recursion', which is just a function which schedules a call to itself. In Csound it might be something like:

------------------

instr 1

aout vco2 0.7, 440

event_i "i", p1, 0.5, p3

outs aout, aout

endin

-------------------------

just a recursive beep, but then then of course you get to edit it into something much more exciting. 

It'd be nice to do this in emacs... hmm

Hi Thorin,

I think it's implemented such that when a new instrument replaces an
old one, existing instances continue using the old instrument
definition.  New notes will use the new definition.  I remember
discussing with Victor and John what to do in this situation, and I
think the current implementation has a dead pool where replaced
instruments go.  That way existing notes can keep processing and do
release segments, and the old definition finally gets removed when all
existing notes are complete.

I'm not sure what happens if notes are currently held when the switch
happens, if they get signaled to turnoff and do release processing.
Perhaps Victor could clarify.

I'll put up a video of a more interesting live coding example in just
a bit that might show a little more of what's possible.

Thanks!
steven
