And YES, that did the trick! Thanks a lot, Clemens. Looks like the drain()
takes a lot longer than I'd have expected (my thought was that it would
return right after the last command bytes have been sent out, and that
the incoming stream would be held

There are two possibilities how the _drain() can be implemented:
1)

No, I checked that. The M3r sends active sensing (0xfe), but I filtered that out.
In the data I get the only MIDI bytes 0x7f are the F0 at the start and the
0xF7 at the very end.

Normally, according to the M3r's SysEx implementation in its manual,
this should give the same output, exactly 23963 bytes.
However, the second version loses about 130 bytes during the transfer.
The strange thing is that the beginning

tells the user to start the dump on the M3r, and then waits for
