RMX-0
RMX-0 is custom firmware for the Erica Synths LXR Eurorack drum module. It is built on Erica Synths’ open-source module firmware (v1.51) and keeps everything the stock firmware does.
RMX-0 is unofficial. It is not made, approved or supported by Erica Synths.
What it adds
| Feature | Summary |
|---|---|
| MIDI input | The OP HH jack becomes a MIDI input, with a channel and note per voice |
| Voice links | Drums 1–3 play as one instrument in unison, chord or poly mode |
| Glide and legato | Per-drum portamento with three curves, and MIDI legato |
| Global reverb | A stereo reverb with per-voice sends, alongside the FX bus |
| Samples | Your own WAV files as oscillator waveforms, with start and end trims |
| LFO shapes | Eleven new shapes, including smooth random and one-shot envelopes |
| Other changes | Pan that moves sounding notes, click-free retriggers, a restart menu |
Kits
- Kits from the stock firmware load unchanged. The added settings start off or at 0, so they sound the same.
- RMX-0 stores its settings after the stock part of the kit file. The stock firmware reads only its own part, so RMX-0 kits still load there, without the additions.
- Kits that use samples, links or glide need RMX-0 to sound as saved.
Getting started
- Install RMX-0 from an SD card.
