Subject	[Cs-dev] issue with audio channels..
	I'm having some niggly problems with audio channels(testing on Linux). I have a simple instrument: instr 1 a1 chnget "leftChannel" a2 chnget "rightChannel" outs a1, a2 endin Samples are being streamed from my frontend to Csound. Everything runs fine until I try to recompile the instrument. At that point I get a crash at csoundReset. Below is the backtrace: 0 0x00007ffff5c65e08 malloc_consolidate malloc.c 4272 1 0x00007ffff5c66b89 malloc_consolidate malloc.c 4247 2 0x00007ffff5c66b89 _int_free malloc.c 4178 3 0x00007ffff6816616 memRESET /home/rory/sourcecode/csound-csound6-git/Engine/memalloc.c 230 4 0x00007ffff696b3db reset /home/rory/sourcecode/csound-csound6-git/Top/csound.c 2672 5 0x00007ffff696bb06 csoundReset /home/rory/sourcecode/csound-csound6-git/Top/csound.c 2787 6 0x00000000004d260e Csound::Reset /usr/local/include/csound/csound.hpp 367 I can't update my Csound build because sourceforge won't let me pull from git.

	Why is CsoundReset called at all when you recompile?

	and while you’re at that, if you can demonstrate the problem with a short program, it will help us debug. The backtrace is pointing to free(), but beyond that I can’t see what the issue is.

	I call CsoundReset because if i don't Csound politely says: Csound is already started, call csoundReset() before starting again?? I can try writing a simple demo. I posted on the off-chance you might spot something obvious in the back trace. Another thing I've noticed is that it is quite erratic. I can always get it to crash, but I never know exactly when it will. I assume there are no issues in calling Csound reset at any stage during a k-cycle?

	But you can recompile without stopping Csound and calling CsoundStart() again, you don’t need to clean it up to recompile (unless you are changing engine parameters such as SR, channels, or other configurations).

	No, I don’t think that is a good idea, csoundReset() should be called only after you stop running csoundPerformKsmps(), and not concurrently with it.

	With regards to the first point about not resetting Csound, channels can change, and so can MIDI settings, or audio settings for that matter. I think it's safest to call reset. The user case here is someone opening a Cabbage instrument, making changes to any part of the csd file and then re-compiling. My code prevents csoundPerformKsmps() from being called during a re-compile but I need to double check this. The erratic nature of this crash seems to lean towards that being the problem.

	I think I've identified the problem here, and see a possible solution. It was a worker thread in the background that was causing the problem.
