Hmmm, does this really work? I don't think so.
Example:
1. status: note on (-> thisByte -> runningStatus)
2. data: key (-> thisByte, ignored)
3. data: vel (-> thisByte, checked against 0, checked againt 0x80)
4. status: note off (read as key !!!)
5. data: key (read as vel, checked against 0x80 !!!)
6. data: vel (read as key !!!)
7. status: note on (read as vel, checked against 0x80 !!!)
The Problem is, that the second data byte is used for the running status
byte test.
Yours,
Jacob
