I've always found the M Audio midi interfaces more reliable from a driver point of view than anything else on the market - particularly the Midisport 2x2. I have owned a couple of Midisport Unos over the years and these work ok, although they are not as robust as the 2x2. A lot of midi interfaces these days don't require drivers...

Medialon's MSC implementation is pretty straightforwards and works nicely with Catalyst.

You need to have same device ID and format ID for MSC to work nicely. GO is the only command worth using. Cue list number and cue number - don't bother with Cue Path.
