Re: [Audacity-nyquist] Loop problem

[Roger D. <rb...@cs...>]

XLISP has some stack and recursion limitations. SIMREP is a macro. I'm 
not sure what's going on, but 130 seems to be the right order of 
magnitude to be hitting some stack limits. You can write a loop that 
repeatedly sets a local variable holding a sound to the sum of the sound 
and another sound. This should accumulate sounds without growing the 
stack. -Roger
