However it is not class compliant, I cannot think of a MIDI Interface that is.
Thanks for your reply, good to read your MIDI journey has been a bit shakey like mine and yeah the midiman midisport 4x4 and 2x2 have served me well for many years. I will probably sell them cheap to someone local starting out with a W7 system or something.
Quite a few MIDI interfaces are described as class compliant now although I think it is a recent W10 thing, not having looked until recently I am not up to speed.https://www.thomann.de/gb/midi_interfaces.html
Out of this lot the iconnectivity, ESI, miditech, claim class compliance while MOTU and M-Audio do not.
I am currently looking at the iconnectivity MIO4....https://www.iconnectivity.com/products/midi/mio4
On paper it looks great.
I am attracted by the ability of it run ethernet MIDI (it does USB as well).
It would appear that ethernet MIDI results in much tighter timing than USB. I used to have an Atari and when I started to use USB MIDI on the PC I did notice a change in the timing for the worse. From what I can gather the USB buss does not prioritise MIDI notes and no matter how fast the USB transfer speed is it is not possible to get away from that, even with USB3. Ethernet works in a different way and I want the tighter timing so I am thinking this box could be worth a punt.
Oh yeah, I think with MIDI timing that some people hear the drift much easier than others and some hear it as the same.
