Connecting MIDI Devices
NoteHound supports external MIDI controllers using Apple’s CoreMIDI framework. Any class-compliant MIDI device — USB keyboards, pad controllers, MIDI pedalboards — can connect and send notes to NoteHound in real time.
Supported Connections
- USB MIDI — connect via Lightning or USB-C adapter
- Bluetooth MIDI — pair wirelessly from iPad/iPhone Settings
Any class-compliant device works without additional drivers.
Selecting a Device
- Open Settings in NoteHound
- Under the MIDI section, tap Source
- Choose your device from the list of detected CoreMIDI inputs
A green dot indicates a connected device. NoteHound auto-connects if only one device is available. Disconnecting a device clears all active notes.
MIDI Indicator Dots
The header bar displays two small dots that show MIDI status at a glance:
- Green — a MIDI device is connected
- Orange (pulses for 100ms) — MIDI data is being received
Key Range
By default, NoteHound listens to MIDI notes in the range C2 — C6. You can expand or narrow this to match your controller:
- Minimum: C0
- Maximum: C9
- Adjust both the low and high limits in Settings
Notes outside the configured range are ignored. Unmapped notes within the range trigger note on/off for the keyboard and piano roll.
Real-Time Display
When you play notes on your MIDI controller:
- The corresponding keys light up on the keyboard panel
- The fretboard highlights the matching string and fret positions
- If edit mode is active, notes are placed in the piano roll
Tip: If your device doesn’t appear in the list, check that it’s connected before opening Settings, or reconnect and then close and reopen the device list.
