A temporary voice, creating a new track, sounds as a piano?  The
original voice and new temporary voice are in different tracks,
but have the same channel number.

So, it /is/ possible after all to have two channels 0 that
sound as different instruments, in different tracks?  Is this
without even using ports?

That would be great!
