My laptops don't have 'real' MIDI ports. One of the desktop machines
does, courtesy of its Audiophile 2496, but I have no 'real' MIDI cables.

Hmmm. I usually go through a 'real' MIDI port. If they don't even appear in Rosegarden then
I wonder if you've got
MIDI set up correctly. Is it a USB keyboard? I believe they are
inclined to have latency problems and you might just be overfilling the
'pipe' :o
It's a MIDI keyboard (Yamaha PSR225GM) without USB
capability. The
XMidiPort provides 2 standard MIDI cables at one end and a standard USB
connector at the other. It is connected into a USB hub that has a number
of other things connected to it (none in active use). OK, just tried going via the MidiSport 2x2 playing
two-handed arpeggios
as fast as I can, and recording in Rosegarden. The only missing notes
as far as I can tell are ones I didn't hit!
I wonder if your hub is a proper 'high speed' one or just claims to be
USB2 compatible and down-converts to USB1.
It's a proper high speed USB2 hub that claims to be compatible with
USB1.1. I have a USB2 scanner hooked up through it, and when I scan
high-res 24-bit color, it scans at USB2 speeds. Having accidentally used
it ONCE on a different machine that had only USB 1.1 ports, I *know* the
speed difference! ;-)
Have you tried it without the hub?
Not yet. I plan to.
