Hi,
need help to find the lowest latency, low jitter MIDI interface, ever made.
i got curiosity from reading this post: "keeps spining in my head"
http://www.gearslutz.com/board/3624005-post2.html Methodology:
the midi loop test, without feedback.
to avoid creating a midi feedback: just select none out midi port in the second midi recording track.
found some strange things in USB1.0,
and diferent perfomance between usb2.0 chips.

so far the best is RME hdsp9632 pci midi, has 61-68 samples of latency.
61 - 68 means: if i record the same midi pattern in loop, measure the sample latency, erase it, and record again, measure again, erase and record again, sometimes latency its 61 and sometimes its 68 samples. sometimes between both aka. jitter.
with a generic PSU, old pc.
is there something better?
please post your Midi Loop Test results, including your computer, if you have an aditional pci to usb card, what brand and model is the chip, what brand and model are the cables you used, midi and usb cables, ... any information.
if someone post the midi loop test results of midiman8x8 or motu MTP AV USB for example,
thats not definitive measurements becouse the variables like USB chip, usb cable, pc, OS, PSU, etc...
if you have same interface please do the test, to see if your system performs better or worse in the midi loop test, and post your results with all the variables.
Midi Tricks: digi001 Asio and midi drivers v6.4 can be used in WinXP MCE sp2, with 975x boards, but... midi needs to be active all the time. "activate the send midi clock and MMC out" and that keeps the midi drivers from sleep/shutdown/automatic self-disable.
