If you are referring to a pedal release, pedals don't work that way. They send a mesasge when pressed, but not when released. So there is no way for MobileSheets to respond to that.

No, the Airstep can send the commands when the Button is released.
You distinguish long press and short press this way.

I cannot use such a device because BT MIDI is not reliable, e.g. not all commands at song load are being forwarded.
