Who wrote this please? Exo maybe? [old link] I can't find ASM versions either... TIA

Yes was me, I don't think there are any ASM optimized versions. I never did any I don't think, nothing on my hard drive at least.

Cheers 😉

Cool! BTW, what is the advantage of a biquad over other filters? I tried researching google with out luck.

I've got optimised ASM for a biquad with coefficients calculated in green. This is OK as long as you're not rapidly automating extreme filter sweeps - otherwise you need the coefficients done in ASM with a hop. I've also got green code modules for peaking/LPF/HPF/APF/shelving filters (however the coefficient naming conventions are all mixed up so it would confuse the hell out of most people!). PM me if you want to follow up.

    It goes on the track you’re editing there, in place of that track’s sound, and into My sounds. Your other tracks stay as they are.

    Want to keep that track’s sound? Start a new song in SynthMaker first (Song › New song), then open this.
