Contents
Features
- 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)
HAGIWO Design
HAGIWO Menu System
- Rotary Encoder: Parameter Selection
- PUSH Button: Parameter Change/Determination
- Menus are not well described on HAGIWOs page - observations
- 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
