Here’s a preset that helps explain the classic acid sound. I’ve been working a lot with creating filters in c++ and wanted to create one that sounded like this preset (or also the digital filter with full drive). It is recreated using a regular lowpass filter (and a lot of resonance) and then some saturation on the output. The saturation on the end exaggerates the resonance and creates this really interesting series of resonances, resulting in the acid sound.
If you’re interested in all the dsp side of things, in my code I used a biquad low pass and some tanh saturation. I haven’t experimented with other types of distortion yet but I’m happy to be able to prototype everything in Vital!
