This is the data: TIMESTAMP IN PORT STATUS DATA1 DATA2 CHAN NOTE EVENT 00025246 9 -- F0 Buffer: 256 Bytes System Exclusive SYSX: F0 00 00 7D 01 04 00 08 00 05 03 00 00 05 04 0D 06 05 SYSX: 06 02 07 01

I don't know a lot about MIDI (just enough to be dangerous), but data is data and if it is giving me an error and I can see that it's not the same than I have to assume that something is clearly wrong. Any idea of what the heck is going on? And I am not trying to spam this place or anything, this is a new development and I fixed the main issue from my other message thanks to BCManager.
