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.) Regards, Clemens
