Erica Synths has open-sourced the firmware for the LXR-02 digital drum machine, making the complete source code available on the Erica Synths GitHub repository. The LXR-02, developed in collaboration with Sonic Potions (Julian Schmidt), is a six-voice digital drum synthesizer with over 30 parameters per voice, a 64-step performance sequencer, insert FX section, four assignable outputs, and full MIDI/USB implementation.
The maker states: “We live in an era of ‘vibe hacking’, where AI-assisted tools let musicians and developers alike reshape software in ways that were hard to imagine only a few months ago. With that in mind, we have decided to open the LXR-02 firmware to the community. We are curious to see what new ideas, features and approaches emerge, and where this experiment will take the instrument.” Erica Synths officially supports only the original firmware; modified or community-developed firmware is installed at the user’s own risk, and support will not assist with issues caused by custom code. The official firmware remains available for reversion, though a damaged bootloader from custom firmware installation would require a paid repair.
The LXR-02 features six drum voices with extensive sound design capabilities ranging from classic analog emulations to crunchy digital textures, voice volume sliders, a flexible 64-step sequencer with performance mode (mutes, rolls, master bitcrush, kit morphing), kit/pattern/performance/song memory, SD card for firmware updates and project backup, USB MIDI, headphone output, and a durable aluminum casing. The hardware remains unchanged at €490 (VAT not included).
This move follows a growing trend of Eurorack manufacturers open-sourcing firmware to extend product lifespan and community engagement. The code is hosted at github.com/erica-synths/lxr-desktop-app and github.com/erica-synths.
