TŒRN is a sampler and step sequencer. The 16×16 RGB matrix is both the display and the keyboard: time runs left-to-right across each row, sixteen voices stack upward, and four rotary encoders on the edge let you draw, sculpt and arrange. Samples live on a Micro SD card; a built-in three-voice synth and two mono synths cover melodic work; eight sample lanes carry drums and one-shots; everything can be recorded right from the device.

This handbook is laid out as a single journey. If you have just received your unit, start with First beat in 1 minute, then read onward — each chapter builds on the one before. Power users can jump directly to Screen index for the "I see X on screen, what is it?" lookup, or to Menu map for the full settings tree.

How this handbook is organised

Three groups in the sidebar follow the same arc a new owner walks through:

  • Get started — a one-minute first beat, then anatomy of the device (hardware, matrix layout, control surface). Read these first.
  • Compose — actually making music: sequencing, pages, advanced tools, samples, sound design, recording, and per-step note detail.
  • Operate — running the box as an instrument or studio member: tempo and MIDI, song mode and saving, the full menu, plus a flat screen index and troubleshooting.

Every chapter shows the matrix display where it applies. Encoder behaviour is given in four-column tables (one card per knob); destructive or sneaky gestures get a callout. Cross-links point to the menu map and screen index whenever a feature has a menu page of its own.
