Frostmod Audio units

Frostmod Audio sells its units on Payhip. For the NTS-1 mkII there are Acidbass Mini, an acid bass oscillator with a diode ladder filter and square or saw wave (pay what you want, from 0 EUR), and C0mp4ct, a 4-voice oscillator with two saw or pulse oscillators per voice, optional supersaw, a bidirectional low/high-pass filter and two envelopes (pay what you want, from 5 EUR). The same developer ID also covers microKORG2 units (Riffosc, Riffgate and FM4OSC, which the product pages say need microKORG2 OS 2.0.2) and drumlogue synths (Riffline and Acidbass). Riffosc, Riffgate, Riffline and Acidbass list a 0 EUR minimum and FM4OSC lists 3 EUR. Only the Riffline repository (documentation and licence file) is public; the units are distributed as binaries. A separate small repository, frostmod/lostnotes, holds a BSD-3-Clause test oscillator for NTS-1 mkII polyphonic note handling and is not part of the shop.

NTS-1 mkII units are loaded with KORG KONTROL Editor. The drumlogue units are copied to the Units/Synths folder over USB mass-storage mode, and the microKORG2 units (.mk2unit) are loaded with the Librarian app or USB mass-storage mode.
