[PD] MIDI / STATUS_BYTE / noteOn - noteOff mesage

[Dan Wilcox]

Pd treats noteoff as a noteon with 0 velocity, hence the [stripnote] object, etc.
 
If you want to explicitly handle noteoff, you can look at the midi tester patch for working with raw bytes...

1. Help -> Browser...
2. Pure Data / 7.stuff / tools / miditester.pd
3. receive [pd channel messages]
