Quickstart Overview

Game System offers 6 sequencer "games" (5 CV/Gate sequencing, 1 Euclidean rhythm generator), joystick/button control, all fully CV/gate controllable.


Panel Controls / Inputs / Outputs

Buttons

Button Function
GAME Cycle "games"; hold 2s to enter settings menu
MODE Game-dependent mode (see below)
RESET Resets open game
CLOCK Tap tempo (internal clock), or clock divider (external clock)

Game Summaries

Game Description Key Controls Outputs
1: Meteor Shower Arcade-style, dodge meteors; random voltage & gates from explosions Joystick: Move; JBtn: # of meteors (hold); Mode: Autopilot O1: Random CV (1V/oct, 0–5V) (on ship/meteor); O2: Gate (on ship/meteor); O3: Gate (meteor/ground); O4: Step clock
2: Music Sequencer Classic 1–32 step CV/gate; per-step voltages JS: Left/right: step, up/down: CV, JBtn: Toggle step (hold: set last), Mode: Dir O1+O2: CV (1V/oct, 0–5V); O3: Gate on active step; O4: Step clock
3: Drum Sequencer Four 16-step gate sequencers (percussion) JS: Move cursor; JBtn: Toggle step (hold: set last); Mode: Flip seqs O1: Top green seq gate; O2: Top red seq gate; O3: Btm green; O4: Btm red
4: Time Traveller 4 outruns "grid", 2D clock divider (div 1–8, offset) JS: Move select out; JBtn: Change selected out; Mode: Free roam (random movement) O1–O4: Gate when given out overlays green clock div
5: Probability Machine 2D probability field for complex/chaotic CV/gate JS: Red arrow pos; JBtn: Complexity (1–4); Mode: Computer control O1: Rand CV w/ O3 gate; O2: Rand CV w/ O4 gate (1V/oct, 0–5V); O3: Gate; O4: Gate
6: Euclidean Rhythms Euclidean gate generator (geo patterns) JS: L/R: seq len, U/D: # of beats, JBtn: Invert pattern; Mode: Dir O1: Random CV (active step, 1V/oct, 0–5V); O2: Gate on active step; O3: Gate on inactive; O4: Step clock

Settings Menu

Press and hold GAME button (2s), use joystick to cycle, GAME to exit. - 1. Clock Source: Internal (tap tempo via CLOCK) / External (use CLOCK jack; CLOCK btn is divider) - 2. Display Brightness - 3. Gate Length: 40/80/160/240ms - 4. Factory Reset: JS UP ×3, explosion confirms - 5. Static Voltages: Select + calibrate CV outputs (adjust trim for 1V/oct 0–5V)
