I've been experimenting with MIDI control from one
machine to another. I
checked the timing of a single note played simultanesouly by instances
of QSynth on both machines and was surprised to hear a very noticeable
flamming. I then replaced the MidiSport 2x2 with my Edirol UA25 and the
flamming disappeared. Both are USB interfaces, btw. MIDI routing between
the machines is handled by a Yamaha MJC8 and has never been problematic
with that box.
So, my question(s): Is the MidiSport just poorly designed
Yes, having to load firmware is awful, but this should not affect
latency. :)
and is there a further condition or module option that
can correct the
timing delay from that unit ?
No.
It is possible that the devices have different buffer sizes, so that
sending multiple MIDI messages at once is more difficult. Have a look
at the respective values of wMaxPacketSize that are shown in the output
of "lsusb -v". Furthermore, the devices can have different internal
buffers.
Which interface did you use for sending/receiving?
