After two years, the 'synthLab Libary,' is almost complete. Would you like to add anything to it? The full listing is 900 lines currently, so here are the signatures for the current methods in it:

would-you-like-your-codebox-in-the-next-synthcore-library

have you check out stkr.waveshaping and those algorithms? They are their own thing already of course. But I think they are great wave shaping algorithms that would add things.

Thats an interesting thread on the forum. Unfoirtunately the links on the strkr website havent worked a long time.

, if someone has interest to implement them in the SynthCore library:

I found in an old archive of mine these functions, if someone has interest to implement them in the SynthCore library:
By the way, great project, Ernest.

I have the whole library downloaded with the algorithms, gen expr. Code etc. I can dig those up though I’m not sure if that’s ok to share this way? I think so.

also the website isn’t active but I believe I got them from the github.

Lemme know if you want them. I also release dance music commercially and have a fairly deep knowledge of sound design. I'm just not quite a coder or Max expert. But if you ever want someone to chat with about this I'm always available for that sort of stuff. Have an interesting idea I refer to as multiband synthesis as well that maybe you could implement better than I...

You're asking for codeboxes, but I do have some gen~ stuff that people might like a lot. Side chain pumper effect that automatically adjust with changing tempo. Multiband algorithmic distortions. Very modern kick drum, with fm noise (using your envelopes). Cascading mixer matrix that's probably wildly inefficient, but still lets you do fairly smooth wavetable fading.

Well Ryan, I'd certainly be glad to hire you for at least a nominal fee to make some presets for Husserl 4, which will also include a multiphonic sequencer like the original Reaktor one, but it's going to be a while before I get to that. It's going to take at least a couple more weeks to finish converting the polyphonic Husserl 2 into the multiphonic Husserl 3.

would you like your codebox in the next synthCore library?
