The MIDI keyboard does not play
Check that MIDI arrives, that the device is on and that the channel listens to the right device and MIDI channel.
- Play a key and look at the MIDI icon at the top: the dot in its corner blinks when MIDI arrives. If it does not blink, REDKEYS is receiving nothing — go to step 2. If it blinks, skip to step 3.
- Tap the MIDI icon and open DEVICES: your keyboard must be on. A device turned off there stays off, even after closing and opening the app.
- On the channel, tap Edit and open the MIDI tab. Under Device, the channel must listen to All devices or your keyboard. A chosen device that is not connected shows as not connected.
- Under Channel, the channel’s MIDI channel (Omni or 1 to 16) must be the one your keyboard sends. The quickest way: tap Learn and play a note on the keyboard. The channel then listens to that device and that MIDI channel.
- MUTE lit on the channel? Mute blocks your keyboard’s MIDI on that channel. Turn it off.
- Is the sound Off here in this part? It takes no notes from outside. See Plays here and Off here.
