Panic and stuck notes

A stuck note keeps sounding because its Note Off got lost. AR Midi Patchbox keeps track of every note it sends and always ends it, even if you changed something in the meantime.

The Panic button

It is the button with the exclamation mark in the top bar, always in view. It sends a Note Off for every note still playing and then All Notes Off (CC 123) on every channel of every output. It also ends the notes held by Hold.

When the app ends notes by itself

• When you change the parameters of a connection, delete it or recall a slot.
• When an instrument is unplugged: the notes of its connections are ended.
• The Note Off of a note always uses the note and channel it went out with, even if you changed transpose or router in the meantime.
• A Note On with velocity 0 counts as a Note Off, as the MIDI standard says.
