received. The bottom line shows the most recently transmitted MIDI message. The display
is mainly used for checking MIDI connections.
MIDI Activity display
When Logic Pro receives more than one MIDI note simultaneously; the respective, held
intervals (between notes) are interpreted and displayed as chords.
On occasion, MIDI modules continue to sound, even when no note data is being sent to
them. This indicates that your sound sources have not responded to the All Notes Off
messages sent by Logic Pro.
To turn off stuck notes
Do one of the following:
µ
Click the lower MIDI Activity display section in the Transport bar.
µ
Click the Stop button twice in rapid succession.
In both cases, reset messages are sent, as defined in Logic Pro > Preferences > MIDI >
Reset Messages.
To stop hung notes
µ
Double-click the MIDI Activity display in the Transport bar (or use the Send discrete Note
Offs (Panic) key command).
Separate Note Off messages are sent for every note, on all channels of every MIDI port,
which should do the trick.
To stop unwanted modulation
µ
Choose Options > Send to MIDI > Reset Controllers (or use the Send Reset Controllers
key command).
