Connect MIDI devices
See your keyboards and controllers, turn on only the ones you want and know what happens if a cable drops.
REDKEYS sees the MIDI devices connected to your computer, up to 32 at a time, with no restart needed.

See and choose your devices
- Tap the MIDI button at the top (its LED blinks with every message). You can also get there through Settings › Devices › MIDI › Open.
- Open the DEVICES tab. Each device shows its name, type, state and a light.
- Play a note or move a control: the device's light blinks.
- Use each device's switch to turn it on or off.
| State | Means |
|---|---|
| Active now | A message from it just arrived. |
| Idle | It has sent messages, but is quiet now. |
| No messages yet | On, but nothing received yet. |
| Off | Turned off by its switch. |
The switch is remembered: a device you turned off stays off after you close and reopen the app, until you turn it on again. While off, nothing from it gets in, and on Windows it is free for another program.
If a cable drops
- The keyboard that leaves releases at once the notes and pedal it was holding: nothing stays stuck sounding.
- When it comes back, the app reopens it by itself, with the same mappings and filters.
- A device that is not connected shows as not connected in the menus, and its mappings stay saved.
