MIDI Devices

The MIDI Device Manager lists all available MIDI devices. Tap a device to connect or disconnect it.

  • Bluetooth devices: BT scanning is off by default; tap the BT icon and grant permission to scan
  • Network switch (iOS/macOS): enables Network MIDI sessions
  • Virtual switch: enables a virtual MIDI port (availability depends on platform)
  • Reload button: fully shuts down the MIDI subsystem and restarts it — useful if devices are not detected or the MIDI stack appears stuck. Last-known devices are reconnected automatically.

Use the bottom bar buttons to access MIDI Mapper. Some general MIDI settings are also available in the main Settings window.

General MIDI Prefs

  • SF Channel: MIDI channel for the SoundFont synth (default: OMNI)
  • Analog Channel: MIDI channel for the Analog synth (default: OMNI)
  • MIDI Thru: forward incoming MIDI messages to connected output devices
  • Pitch Bend Range: sensitivity of incoming pitch bend in semitones

MIDI Mapper

Lets you control Hemiola parameters via MIDI (UI mode) or forward and transform MIDI messages (Custom mode).

  • Tap an entry to activate or deactivate it
  • Filter the list by message type; "activate all visible" applies to the filtered set
  • Add custom mapping: define name, in/out channel, command, and data; tap the settings icon to edit or delete
Note

Long-tap the Add button to reset all mappings to defaults and delete all custom entries.

MIDI Console

Displays a real-time list of recently received MIDI messages. Useful for testing and diagnosing MIDI connections, and for identifying the right channel/command values when creating MIDI Mapper entries.

  • Access: long-tap the MIDI icon in the bottom tab bar, or long-tap the MIDI icon inside the MIDI Device Manager screen
  • Tap the Clear button at the bottom to erase the current message list
