User reviews

Should have stuck with FD-1

I saw where someone complained about the GarageBand crashing but I figured a year after the developer responded it would have been fixed by now. Even in Cubasis 3 it’s very glitchy. Is it worth hoping for fixes in future updates?

Good but broken in bm3

Great sounding filter however I have a bug on BeatMaker 3 which makes it unusable.. clicking / clipping sound regardless of parameters.

Would be great to have wider lfo speed, and ability to have tempo sync selectable for each lfo, and a comb filter would be cool too !

Lovely filter

I really like SF-1.

A must have in anyone's kit.

Great Filter

Don’t think because it’s free it’s not good. I reach for it before the toneboosters dual VCF quite often because I get on well with the big knobs on the interface. It sounds great to my ears and easy to get some modulation going. This was good enough to convince me to get the RE-1 tape unit, which is a beast.

The FD-1 is my favorite though. That thing is endless rhythmic and textural experimentation. Pure brilliance.
