I'm running into many problems running BK9 midi files on a iPad (using the app Sweet Midi)or Laptop (using QMidi). Here's a simple example.
Playing Blue Christmas. Drums on channel 10 are BK9 make up tool StudioX Kit2 and I have the file saved and I have 'frozen' the file after I saved it. In Qmidi the drums play fine. I also have a fake vocal part which is supposed to play BK9 Jazz Scat (0655). But Qmidi plays it as GM 82 Sawtooth on midi channel 2. So...it is translating the drums fine but not the Jazz Scat. ( or mc10 but not 2). bass on mc1 is fine.

This is just 1 example.........

Some times SOME files played in Qmidi silence the Upper 1 on the BK9.

Sometimes, when I first play a file, a properly frozen BK9 file plays nonsense - like it's not 'initialized' Drums are thud thud instead of tick tick!

I must add that all these files play fine on the BK9, itself. . I have a feeling this has something to do with BK9 Midi sets ......
