Description
FrostMod Audio publishes two drumlogue synth units in logue SDK 2.0 format on Payhip, both with a price of 0 and optional donations. Riffline is a four-voice polyphonic supersaw synth with two ADHR envelopes (amplitude and modulation), one LFO per voice and a switchable 2-pole high-pass or low-pass filter; the page says polyphony needs sequencing over MIDI. Acidbass is a monophonic synth inspired by classic acid basslines, with a saw or square oscillator, a 4-pole diode ladder filter, separate amp and filter decay envelopes, distortion before or after the filter and a slide control, spread over three parameter pages. Source code is not published.
