Monitor and reset MIDI events in Logic Pro for Mac

In Logic Pro, do one of the following:

• Click the lower section of the MIDI Activity display.

• Click the Stop button twice in rapid succession.

• In Logic Pro, double-click the MIDI Activity display (or use the Send discrete Note Offs (Panic) key command).

This sends separate Note Off messages for every note, on all channels of every MIDI port.

• In Logic Pro, use the Send Reset Controllers key command.

The Send Reset Controllers command sends messages on all MIDI channels to all available MIDI outputs for the controller types selected in the MIDI Reset Messages settings pane. When Control 121 (Reset Controls) is selected, control change message #121 (Reset all controllers), with a value of 0, is sent on all MIDI channels and outputs used by defined instruments. This neutralizes all MIDI controllers, such as modulation or pitch bend wheels.

• In Logic Pro, use the Send Maximum Volume key command.

This transmits a control change message #7 (main volume), with a value of 127, on all MIDI channels and outputs used by defined instruments.
