Does this really make it impossible to check DBC?

Can this ever make the MIDI rate less than 3125 bytes per second? If not,
then we can simply apply this quirk to all devices.
(Which reminds me: we must ensure that the rate never exceeds 3125 bytes/s;
most other devices have a smaller buffer than Fireworks devices, and even
those will eventually overflow.)

Clemens
