Hi guys,
first post for me. let me say, i love CSound! and sorry if you youve seen
this already, i had mailing list issues.
Hans Mikelson posted on CSound magazine this interesting Time Domain
TimeScale algorithm based on SOLA
http://www.csounds.com/ezine/spring2000/processing/
I love his explanation and the sound is good, but i needed a dynamic pitch
shifting, that is, one that can change pitch in k-rate, i messed around with
his code but i made more mess than i can cleanup, so i need your help.

this is Mikelson's version. very clear and neat


now, how would you make a auto-tuner out of this? 
youll have to have a pitch detection algorithm (PDA) and the complicated
thing is i want to scale a sample that runs in a loop, so... this is my code
with event flow at the bottom:


it became kind of global variable - p-rate nightmare ;/
the Init method initialize any global variable so the compiler wont be
angry.
setup initializes the Process instrument that runs as the Always On instr
while performance.
Pseudo Midi given by the note in i1.
i1 trigger the SOLA instr.
the SOLA instr takes global params from Process like the pitch of the
current k-frame, and creates global signal gashft1 that is picked up by
Process and mixes with the fade mechanism and heads out.
the original sound is a loop, since its beeing read by a table3 opcode, i
used a phasor to keep track of where is the pointer of the sample should be
on the table. the thing is, that phasor must stop running when activating a
note on SOLA, so the reinit section was added with hope to solve this.

now, what is the problem? simple, no sound!
i tried measuring rms  of the ga coming out of SOLA, it measured 0.2 RMS.
that's wierd. im i reading the table wrong? what can cause this behavior?
how is best to debug this? what tools to use? is this idea possible anyway?

thanks to all readers and answerers.
