STEP 1

Start & Play

Click Switch on, then tap PLAY. All 8 tracks start jamming together: T1 303 A, T2 303 B, T3 808 Drums, T4 909 Drums, T5 Breaks, T6 FM, T7 Sub, and T8 MIDI.

STEP 2

Twist the Knobs

Drag K1 Cutoff and K2 Res up and down to hear the 303 diode-ladder filter bite and scream. Drag TEMPO to adjust BPM.

STEP 3

Compose & Edit

Compose using panel knobs & silicone keys in REC mode (or enable Screen Edit above to click and draw directly on the LCD grid!).

STEP 4

Record with Keys

Tap REC, then press the 27 silicone keys. The note pitch is punched into the step, and the sequencer automatically steps forward!

Hardware Panel Controls

  • MASTER: Output volume.
  • SELECT: Scrubs active step (1–32) or transposes pattern with EDIT.
  • TEMPO: Sequencer speed (50–240 BPM). With EDIT: Swing (0–75%).
  • TRACK: Switch active track (T1..T8: 303A, 303B, D808, D909, BRK, FM, SUB, MIDI).
  • K1 (Cutoff): 303 Filter Cutoff frequency / note pitch.
  • K2 (Resonance): Squelchy diode-ladder resonance / gate length & tie.
  • K3 (Decay): Envelope decay / curve modulation value.
  • K4 (Accent): Accent overdrive intensity / pattern length.
  • OCT- / OCT+: Scroll grid octave window (C1..B5).
  • 16 White Keys: Direct 16-step drum programming (1–16 or 17–32) on 808/909 tracks, and pitched note playing. Integrated LEDs illuminate pressed keys and active steps.

Pro Tips & Acid Tricks

  • Acid Slides: When two consecutive steps have notes and the first step has Tie enabled, the pitch glides smoothly (portamento) without re-triggering attack!
  • Punchy Accents: Set velocity to 105 or higher on a step. The 303 filter snaps wide open with saturated overdrive!
  • Modulation Curves: Press ENV to switch into CURVE view. Click in the grid to draw filter cutoffs or MIDI CC automation.
  • Silent MIDI Mode: Press LFO until it says MUTE. The internal audio is silenced so you can sequence hardware gear with zero latency!
