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
  • O: Offset (Upper right, bottom row)
  • L: Limit (lower left, top row) - number of steps
  • M: Mute channel (lower left, middle row)
  • R: Reset (lower left, bottom row)
