Frostmod Audio have released a new synth engine for the Korg Drumlogue hybrid drum machine/groovebox. It's in public beta and is released under a pay what you like license.
"In an attempt to be the change one wants to see, namely a better ecosystem for an underappreciated drum/plugin machine, I decided to start creating some of the plugins I myself would use on it.
Riffline is a four voice single oscillator supersaw type synthesizer plugin with a few modulation options and a switchable HP/LP filter.
Riffline is available for free, currently in the releases section of this repository while I work on a Frostmod Audio website. The intention is to keep this plugin as a free/donation plugin."
From the docs, I can see that it features 7 saw oscillators, 2 filters (HP & LP), an LFO (with envelope-controlled rate) and two ADSR envelopes. With some motion recording and the Drumlogue's selection of weird effects, I can see it being pretty fun! I look forward to Frostmod's future ideas!
