No sound
From the Master meter to the channel: what to check, in this order.
Go in order. Most cases are solved in the first three steps.
- Play and watch the L/R meter, top right. If it moves, REDKEYS is playing: check the cables, the interface volume and the PA.
- Check the audio interface in Settings › Devices: Audio interface shows its name, or — when none is open. Tap Open and pick yours under Audio device.
- Play a note on the on-screen keyboard (Desktop and Tablet). If it sounds from the screen but not from your keyboard, the problem is MIDI: see The MIDI keyboard does not play.
- Look at the channel: Choose means it has no sound yet (tap it and pick one); Off here means the sound is off in this part (Plays here and Off here).
- MUTE lit on the channel? Mute blocks your keyboard on that channel. Turn it off.
- Check the channel fader and the Master: tapping the L/R meter opens the Master and the buses.
