Code Project - I probably spend more time on this website than any other.
KVR Audio - When I'm not at Code Project, you can usually find me on the DSP forum at KVR Audio. The folks there have been very helpful over the past couple of years. A lot of what I know about DSP programming has come from discussions I've had there.
Designer Monkey - Rick Christy of Designer Monkey is the artist who created Cobalt's interface. He's one of the best graphics artists around.
Atomsplitter Audio - Atomsplitter created a good chunk of Cobalt's presets. He also helped did some beta testing for me. Be sure to check out his VST plugins. I'm always impressed by their originality.
ProSounds - ProSounds has a vast collection of professionally programmed patches for a wide variety of VST synths. I've created two banks for them so far, one for the PS-1 synth and one for the V-Station. Check them out.
sygyt Software - sygyt has created an amazing application called the Overtone Analyzer. It can be used as a sound analyzer and a visual feedback tool as well as an interactive visualization of music theory. My piano control served as a starting point for their keyboard code. It's gratifying to see my code being put to good use.
