Fluyt
Nine engines from Felucca, the open M-VAVE FM-1 firmware, ported to the drumlogue as separate synth units with Felucca's own presets, from two-oscillator analog to six-operator FM. Also built for the microKORG2.
- Distribution
- Prebuilt image you flash yourself
- Requires stock
- 1.00 or later (logue SDK 2.0 units)
- License notes
- Build scripts are MIT; each unit's Makefile is the logue SDK's (BSD-3-Clause, KORG); the FM6 core is an msfa/Dexed port (Apache-2.0). See docs/LICENSING.md.

Description
The units are ANALOG (two-oscillator virtual analog with a resonant filter, 12 presets), TRIO (three-oscillator paraphonic), PHASE (phase distortion), LOFI (aliased low-bit pulse), WHEEL (tonewheel organ with rotor), NOISE (filtered noise with sample-rate crush), FORMANT (vocal synthesis), DRUM (a General MIDI numbered kit) and FM6 (a six-operator msfa port). Each plays from the panel, a keyboard or the drumlogue's sequencer, with up to 20 parameters over five pages generated from Felucca's own parameter tables. Felucca is included unmodified as a submodule at v1.0.2, with its lookup tables regenerated for 48 kHz; three constants written into Felucca's source stay at 44.1 kHz, so NOISE, FORMANT and FM6 envelopes run about 8.8% off. Felucca's sample-based engines and PHYS are not ported. The same nine also build as microKORG2 oscillator units (see the separate microKORG2 entry).
Install notes
Download the prebuilt units from the itch.io page (name your own price, free allowed) or build them with build.sh in the logue SDK container. Start the drumlogue in USB mass storage mode and copy the .drmlgunit files into Units/Synths, then pick the unit in the Multi-Engine part.
