Features[edit]

  • GATE Sequencer
  • Based on HAGIWO Euclidean rhythm sequencer
  • OLED Display: 128*64 size
  • Rotary Encoder: Parameter Selection
  • PUSH Button: Parameter Change/Determination
  • Trigger Output: 6CH (0-5V) Trigger Input: 1CH (0-5V)

  • Rotary Encoder: Parameter Selection
  • PUSH Button: Parameter Change/Determination
  • 6 Parameters - Arrow points to current channel/option
    • 1-6, R: Select channel 1-6 (upper right, top row), Random
    • H: Hits (Upper right, middle row) - Number of points
      • Number of outputs out of 16 steps
    • O: Offset (Upper right, bottom row)
      • Shift the start of the rhythm by offsetting LIMIT
      • Return to the first step when there is a trigger input for the number of times the set value is set
        • For example, if you set it to 5, it will return to the first step after outputting 1~5 steps. It can be used in a polyrhythmic way
    • L: Limit (lower left, top row) - number of steps
    • M: Mute channel (lower left, middle row)
      • Eliminates the trigger output of the selected CH.
    • R: Reset (lower left, bottom row)
      • Press the button to return the playback step of all channels to the first step
