Hey hey everyone,
sorry for cross posting. I released a set of three Csound User Defined Opcodes 
today. A pitch correction (autotune style), a channel vocoder (using an 
FFT-based technique) and a free pitching module, that pitches a voice - 
whichever pitch it has - to the MIDI notes received.

All opcodes tested with Csound version 6.05, but should work on version 6.0.

https://freeshell.de/~silvain/cs_voice_processing-0.5.tar.bz2

I've tested them live on a 3 gHz CPU running a Linux commandline. With a 
hardware sample buffer (-B option) of ifftsize they work in realtime.

Any feedback and improvements are welcome! Thank you.

It would be nice if these could be added to the UDO database.
