tbd-16 in action

Meet tbd-16

Connect USB-C power and speakers or headphones: tbd-16 boots straight into the Groovebox, with no computer needed to play.

It is a finished instrument, but not a fixed one. Alternative firmware can give the same hardware a different role. You can write your own, too.

From prototype to production

If you saw tbd-16 at Superbooth, there is more here now. The production hardware brings significantly improved audio quality, a second stereo audio input and a separate headphone/cue output.

The Groovebox firmware has developed alongside the hardware, with new machines, effects and sequencing features.

Find your sound. Choose your machines.

Tracks aren't tied to a single sound engine. Choose any drum machine for any drum track, or any synth machine for any synth track. Each machine brings its own synthesis method and controls.

01

Drum machines

Analogue-style, digital, FM and 606-inspired drums, with controls for shaping each voice.

02

Synth machines

Mono and polyphonic synthesis, wavetable, physical modelling, speech synthesis and acid bass.

03

Samples & external audio

Use your own samples and bring external audio into the mix. Keep projects and sounds on the included, user-replaceable 32 GB microSD card.

Effects & master processing

Two dedicated FX tracks use the same flexible machine concept. Choose delays, reverbs, modulation or Beat Repeat effects.

Shape the full mix with master bus compression, sidechain and a DJ-style filter.

Sequence, play and perform

Program a pattern on the 16 RGB step keys, then shape individual hits with the four endless potentiometers. Parameter locks, velocity and note length give each step its own sound; probability and retriggers introduce variation.

  • Independent track lengths, LFOs and random modulation
  • Pattern window, rotation and flexible time signatures
  • Arpeggiator, Euclidean sequencing and 16 scenes per song
  • Metronome with cue routing

Connect your setup

Connect external instruments, process incoming audio or sync with a modular system. Ableton Link and automatic MIDI clock sync keep tbd-16 in time with the rest of your setup.

A standard 5 V USB power bank can power the instrument away from the studio. The mounting accessory is included.

Revised production hardware · separate main and headphone/cue outputs

Audio, with room to grow.

Two stereo inputs, a stereo main output and a separate headphone/cue output. USB audio also works in the default Groovebox firmware. The second audio input shares the MIDI Input 1 socket in its switchable mode. A dedicated control sets headphone volume.

Bring your instruments.

USB host and USB MIDI device. Two TRS MIDI inputs and two TRS MIDI outputs. Switch MIDI Input 2 to Eurorack clock/reset to sync with a modular setup. Novation Launchpad Mini MK3 and Launchkey Mini MK4 integration extends the controls beyond the front panel.

A browser is all you need.

Manage samples, presets and configuration in the WebUI over USB or Wi-Fi. It runs in your browser: no companion software to install. The instrument itself doesn't need a computer to play.

Run your own apps

Switch apps from the SD card at reboot. Run MCL (MegaCommand Live), Justin Mammarella's sequencer for the Elektron Machinedrum, ported to tbd-16. More alternative firmware is in development.

And yes, it runs DOOM.

Two development paths into TBD-16: custom apps run on the RP2350B for controls and MIDI, while custom DSP plugins run on the ESP32-P4 for synthesis and effects. Both can work together in one instrument.

Your code. Your instrument.

Write your own apps, sound engines or firmware. Change how tbd-16 plays, how it sounds, or both.

The firmware and DSP code are licensed under GPL 3.0, with source access initially available to device owners. No paid SDK or access tokens.
