Hello
I have this problem too. Today everything I have recorded plays at 40-50 bpm.
Today I recorded a midi file and had a play around editing the file. After that I loaded a project I am working on and it played at 40-50 bpm. I loaded another project and it was the same, everything I have recorded now plays at 40-50 bpm.
This is frustrating, just about every time I open Mixpad something is not going right.
regards
Garry
