Works with any class-compliant USB audio interface, or use HDMI for demos.
Questions? See the FAQ.
Designed for Raspberry Pi 2B Rev 1.2 (64-bit), 3, 4, 400, 5, 500 and Raspberry Pi Zero 2W (64-bit). Works with class-compliant USB audio interfaces from Focusrite, Steinberg, Behringer, MOTU, PreSonus and more. USB audio takes priority; HDMI is the fallback. Demo mode runs for 3–5 minutes per boot and routes audio to HDMI only.

C64 MOS 8580 SID
PWM arpeggios, per-channel filter sweeps and GM drums recorded on the dev workstation running the Pi 4 + USB audio interface.
AY-3-8910 / YM2149
Metallic PSG squares, crunchy noise drums and vibrato leads that nail Amstrad and Atari ST energy.
Roland-Inspired
TB-303 bass, TR-808/909 drums and lush Juno/Jupiter pads for club-ready arrangements.
Commodore Plus/4 & C16 TED
Two-voice, lo-fi TED textures with crunchy noise drums-perfect for Plus/4 nostalgia, loader music and harsh retro cues.
ZX Spectrum 1-Bit
Hyper-minimal pulse synthesis for brutal drum workouts, intros and glitch textures.
High‑performance GM2 engine with intelligent voice allocation and a professional gain‑staged mix bus. Built to run as a dedicated Raspberry Pi hardware instrument.
At its heart, Subsynth runs 320 simultaneous channels across five classic waveforms (square/PWM, triangle, sine, noise, saw). 16‑part multi‑timbral with up to 128‑note polyphony.
Per‑channel effects: delay, comb filter, flanger, phaser, bit‑crusher. Master bus: state‑variable filter, stereo reverb, chorus, ping‑pong delay, compressor/limiter. Real‑time monitor shows live activity, levels and CPU usage.
Whether you are driving Subsynth from a DAW, a hardware sequencer or a live controller, the appliance behaves like a dedicated GM2 module with modern routing and control options.
Need the full rundown?
140+ pages covering every effect, parameter, soundbank, MIDI control and more fully documented for musicians and tinkerers.
Full GM2 including dual drum channels (10 & 11) and Dynamic Rhythm (Bank 0x78). Standards‑compliant program/drum maps, ready for DAWs and hardware sequencers.
4360+ NRPN parameters, pitch bend, modulation, sustain, expression, and poly/channel aftertouch. Sample‑accurate timing with JACK for tight feel.
Sub‑3ms latency, unity‑gain headroom, 44.1–192 kHz support and a polished mix bus (reverb/chorus/delay/compression). Render stems faster‑than‑real‑time to WAV.
A detailed GM monitor displays channel activity, voice usage and levels so you can see exactly what your MIDI files and controllers are doing in real time.
The Raspberry Pi boots directly into the Subsynth environment. No desktop login or manual launching – power on, wait a moment, and your synth is ready.
Builds are optimised and hardened for the specific Pi model you own. Once your image is installed, it behaves like a dedicated piece of hardware rather than a general-purpose computer.
Intuition Subsynth runs as a dedicated, real-time hardware synthesiser on selected Raspberry Pi models. Power on your Pi and play – no desktop environment required.
Official images are available for:
Works with any class-compliant USB audio interface! Focusrite Scarlett 2i2, Steinberg UR22, Behringer UMC204HD, MOTU M2, PreSonus AudioBox and many more. Plug in and go, no drivers required!
Each purchase includes a bootable SD card image with a tuned real-time configuration, JACK audio and Subsynth set to auto-start on boot for an appliance-like experience.
Clear answers to the most common questions from buyers.
A custom, hardware‑locked SD card image for your Raspberry Pi, the user manual, and email support. One license covers one Pi.
Yes. It’s General MIDI Level 2 compliant with dual drum channels and Dynamic Rhythm. Standard controllers, pitch bend and aftertouch are supported.
With JACK on a supported Pi, expect ~2.9ms round‑trip latency and sample‑accurate MIDI-ideal for performance.
Raspberry Pi 2B Rev 1.2/3/4/400/5/500 or Zero 2W (64‑bit). Any class-compliant USB audio interface (Focusrite Scarlett, Steinberg UR-C, Behringer UMC, MOTU M-Series etc) for studio‑quality output; HDMI audio works for demos.
Request a demo image and run it on your Pi. Demo mode runs for 3–5 minutes per boot with a curated set of instruments.
Absolutely. Use Rawland for lush pads, plucks and 303 bass, then shape with per‑channel FX and the master chain for contemporary, mix‑ready results. Or just make your own, it's a synth not a tone-generator!'
