Hello M.G.,

Perhaps we can find a "repro" for this, that is, a set of steps that consistently reproduces the symptoms of the underlying bug. You already have some ideas about how to create this repro. If you come up with the repro steps, please let me know.

It is very unlikely that shifting notes between tracks would cause the channel assignment or volume level of a track to be changed. It is much more likely that the problem has to do with the Split Hands command.

Cheers
