What's New in KeyPad MIDI Controller

1.15

October 2, 2026

Added the Piano Fader view. Pick it from the View menu to replace the XY pad and drum pads with four CC faders. A pill under each fader shows its CC number, and the live value while you move it. Tap the pill to assign any CC. Save fader CC assignments as CC Set Presets, then recall or delete them from the same pill menu. Fader positions and CC sets are saved with your session or AUv3 project.

1 problem

When I try to use the mod wheel or pitchbend it lags and it hits a very high pitch noise

Great app. Only one issue, not a deal breaker…

Loving this app as a means to play a particular sound effect. Issue is the stomp midi controller I’m using has no ability to change velocity, and the velocity control in the app does not affect incoming midi notes.

So please, in next iteration could you also include an assignable volume control.

So good!

Love all the different keyboard modes, and the ability to apply a scale to each of them! This beats out another paid app I have for a midi controller.

The devs were also real fast to respond to a request! Thank you!
