Ahead of the 2026 NAMM Show, Bastl Instruments has announced that it is open sourcing the firmware for three of its designs, and making them available as DIY kits:
“We are excited to not only announce the late arrival of the Citadel Alchemist Eurorack module to the party, but to let everyone know that all the instruments are now available as DIY kits and that we are partially open-sourcing it so the world we started could be expanded by many others.”
- Alchemist – Compact Patchable Hybrid-Synthesis Instrument with MIDI
- Wave Bard – Compact patchable stereo sample player
- FX Wizard – Compact patchable stereo multi-effects
The kits have a standard hardware design, but with different firmware and faceplates. Both standalone and Euro format kits are available.
