DUELL
MultiMorphing
Bitimbral Synthesizer
by OSCILL/R
This is the first public beta of DUELL, a free, open-source bitimbral firmware for the M-VAVE FM-1. It is based on Felucca.
What is in this release
The browser emulator only. Download the zip, or just open the hosted version at https://oscillr.github.io/DUELL/emu/ once the page is live.
- Two complete parts, playable in three modes: LAYER, SPLIT and STEREO
- MORPH between two versions of every patch, with a smart randomizer
- 12 sound engines and a factory palette of about a hundred sounds
- Two envelopes, two LFOs and an 8-slot modulation matrix
- Ducker with MIDI sidechain, EQ per part, ping-pong delay and the SHIM and RESO reverbs
- 16 multis and 16 patterns
What is not in this release
There is no firmware download yet. The firmware has run on one real FM-1, but the way back to the official firmware has not been tested yet, and more hardware testing comes first. Please do not try to flash anything for now.
Good to know
- The emulator keeps its data in your browser. After an update, clear the site data for the page. "Download saved data" makes a backup first.
- Browser MIDI forwards notes, CCs and program change, but not clock or SysEx.
Feedback
Bug reports and ideas are welcome in the Issues tab. There is a bug form with the details that help most. Please say which browser and which part of the emulator you used.
DUELL is licensed GPL-3.0-only, like Felucca. No warranty. It is not affiliated with or endorsed by M-VAVE. Thanks to Baud Girl, Leo Kuroshita and the whole community. The SHIM and RESO reverbs come from JIANT.
