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.”


The kits include:

  • 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.

The Kastle 2 kits are available now for €128, while the Citadel versions are €194. Pre-assembled versions are also available.

Stylophone Intros On-The-Fly Performance Sequencer


Ahead of the 2026 NAMM Show, being held Jan 22–24 in Anaheim, California, Stylophone has introduced the Stylophone On-The-Fly Performance Sequencer, the latest addition to their Stylophone Pro Range.

As its name suggests, the Stylophone On-The-Fly sequencer is designed for real-time performance and programming. Every control responds instantly, letting you shape patterns with rhythm, pitch, and playing-style variations while the sequence is running.

With full Eurorack CV, Gate, Sync, and MIDI connectivity, it integrates into modular, MIDI, and hybrid setups. They say it also scales up easily with more units into a multi-sequencer system.

Features:

  • Performance-focused 16, 32 or 64-step sequences with 8 live-switchable pattern chains each
  • Instantly switchable sequence directions, Forward, Reverse, Bounce
  • On-the-fly switching between 24 sequence memories with per-step pitch and duty cycle
  • Hands-on control — tweak everything while playing
  • Musical scale & transpose control (Knob, CV, or MIDI)
  • Creative step effects: skip, rest, tie, glide, ratchet, random
  • Manual performance button for instant fills and movement
  • Groove controls: tempo, swing, lead/lag timing, note length, gate length (duty)
  • Loop Record your performance up to 1024 steps
  • Per-step gate outputs (8 separate gate outs plus the summed Gate Out)
  • Eurorack-ready CV & Gate I/O plus MIDI & Sync
  • Expandable system — link and sync multiple units for larger setups

Details are still to come at the Stylophone site.
