Ok! I have my own business coming up. But I'll perhaps contact you privately with some questions. I think the C/C++ API has changed a bit since the last copy of the Csound book that I have was published (its not in front of me so I have to look it up). I'll need a reference to a tutorial or something similar about how to extend Csound via home-grown opcodes.

I also have a question regarding how to encapsulate other opcodes into a new opcode: does one call the opcode from C/C++? Is that possible, or is it more about something akin to cutting and pasting source signal code from the opcode one would want to use. I assume the former is possible, but maybe not.

As for glassandi w/o noise...I'm not sure how this new code (based on Victor's) would handle that situation. I didn't test for it. :)

I meant "I have my own busy-ness" coming up...not "business".

A commercial plugin, you mean? Is that why you cannot use GPL3?

I'm confused...sorry.

Not commercial. But Csound itself is LGPL which is open source whereas GPL is free software. They are not compatible. 

Best,
