Title: Pitch Bend Data1 value in Output monitor
Post by Peter L Jones on Jan 16^th, 2005, 10:06am

I've just noticed that in Version 7.0.0.365, the "Monitor - Output" window seems to have a bug. It seems to display pitch bend messages with the "data1" byte in "data2" and zero in "data1". As does the "Monitor - Input" window, now I look. They get it right for Ex 7F 7F, though.

The "MIID Status" window shows the correct value (so its not my pitch bend wheel ;-) ).

That is likely an artifact of your controller. One of my devices (Hammond XK2) does that also, while the other (Roland A90) has finer granularity, but they are both correct. I will admit it can be disconcerting to always see 00 in the Data1 position.

The MIDI Pitch Bend message has the LSB in Data1 and the MSB in Data2. It is always a 3 byte message resulting in 14 bit magnitude. Min (-8192) = 00 00, Center (0) = 00 40, Max (+8192) = 7F 7F. To see the actual MIDI messages that arrive, turn on Logging and set the format to Raw MIDI Messages.

They put the MSB is Data2???? Good thing I asked... I'm writing some software and assumed it was the other way round... ::)

Thanks!
