I think the organelle would be a great interface for this effect. Anyone with the know how and inclination want to make this? I’m clueless at programming but a real ideas man xD
Somebody just uploaded a wow and flutter effect to patchstorage, not tried it but that’s great for a gently slewed sound. Does the sp303 play a looping sample of crackling or something? You could add a looping a sample of vinyl crackle to that other patch and probably be pretty much there. Search around for compression patches (here’s one goodie - https://patchstorage.com/compressor/ ) and feed everything into one of them.
It use is for a really punchy over the top compression, not so much the crackle
Yeah just leave out the crackle then innit
