AllNotesOff.ms (0.1) 2018-10-16 12:10 pm This plugin plays a MIDI "All Notes Off" message, at the playback position at which it is inserted. It uses the staff's port and channel number. This page includes a description of the various MIDI messages.The following clip demonstrates the object's operation. The two tied half notes create an intentional stuck note (the second note is muted), which can be heard playing during measure 2. The AllNotesOff.ms at the start of measure 3 will stop the stuck note.!NoteWorthyComposerClip(2.751,Single)|Clef|Type:Treble|TimeSig|Signature:4/4|Note|Dur:Half|Pos:1^|Note|Dur:Half|Pos:1|Opts:Muted|Bar|Note|Dur:4th|Pos:-6|Note|Dur:4th|Pos:-5|Note|Dur:4th|Pos:-4|Note|Dur:4th|Pos:-3|User|AllNotesOff.ms|Pos:-5|Bar|Note|Dur:4th|Pos:-2|Note|Dur:4th|Pos:-3|Note|Dur:4th|Pos:-4|Note|Dur:4th|Pos:-5!NoteWorthyComposerClip-EndIt occurs to me that this object could be expanded into a more general "channel mode message" object, which could be used to generate other MIDI messages such as All Sound Off, Reset All Controllers and Local Control On/Off. If there is interest in these options, I can make the necessary changes (which would most likely result in a different named object).
