TŒRN

Imagine painting rhythms and melodies with light on a glowing 16x16 RGB LED grid, where every pixel pulses as a sequencer step, modulator, or performance canvas. The TŒRN open-source sampler-sequencer turns DIY dreams into standalone reality, powered by a 600 MHz ARM Cortex-M7 processor on Teensy 4.1 for real-time audio magic.

Craft 16-bar patterns across 16 pages—up to 256 bars total—with autosave, real-time sample switching for 999 WAV files via SD card, and scale-aware random note generation that sparks creativity. Trigger 8 sample voices with trim controls, 3 analog-style drums (bassdrum, snare, hihat), and poly synths (one 3-OSC voice, two 2-OSC voices), all laced with per-voice effects like ADSR, bitcrusher, filters, flanger, and reverb—plus live transpose, shift, copy/paste, and assignable channel filters.

Fully Arduino-compatible and community-driven, this portable digital beast outputs MIDI and invites firmware tweaks for endless evolution.
