I have a Komplete M32. It is detected by various DAW systems and standalone sounds. However, after a while, some packages are quicker than others, it is still detected as being attached, but is either not selectable as an input source, or no midi data is received from it. I tend to blame the M32 because I also have an Arturia Mini which works fine.
M32 has latest firmware, and it lightly used.
Any ideas?
