Topic: Roland Mobile UA -> good and inexpensive 4-channel USB interface

Hi all,
I place this in an extra post because it would have saved me MANY hours had I found out about this a few weeks ago:

following a recommendation by Leandro Duarte I ordered the Roland Mobile UA, and I am VERY happy.

It offers 4 independent output channels recognized by Pianoteq and working (tested with headphones). As I only have two speakers connected right now, I tested playability in a two channel setup. Very impressive, to my ears no discernible latency at 256 samples. I test latency by having the Casio's internal system playing in parallel to the MIDI-Pianoteq sound. This is not a numerical measurement, but if I can't distinguish two different sounds on a keystroke I figure it will not affect my playing at all. I can hear a slight latency at 512 samples.

So: sleek package not larger than an mobile phone, easy setup, great sound, minimal latency, 4 channels, for €100 -> this is a very clear recommendation.
The only downside is that it seems to be just out of production, I've picked it up on eBay. Another limitation might be that there are no Linux drivers, I have not tested it on Linux yet. OSX and Win 7-10 are working.

Best wishes
Andreas

Roland doesn't support Linux, in fact many audio interface vendors don't do this, so you can try using generic drivers, but that could yield mixed results...

Hard work and guts!
