OctaMED (or CAMD or the interface driver?) doesn't support an external clock? Can it act as a clock source? EDIT: OK, so I guess CAMD just passes along system messages, and it's up to the devices and sequencer to decide how to use and interpret clock messages. There's an old thread here on Amiga.org talking about MED supporting legacy MIDI clock messages but not MIDI timecode. Sounds like Bars 'N Pipes is good to go, though. Wish I still had my AMAS. Just have the DSS8+ now and no MIDI interface. Don't feel like wiring my own (which I'd probably foul up anyway).
Yeah, OctaMED's MIDI support wasn't the most amazing thing ever... I didn't bother messing around, this was 6 years ago... got the job done... haven't worried about it since.

I have a Creative/E-mu 1212m in my PC. It's a decent card, but I'm not very fond of the software interface.
Oh E-mu... how the mighty have fallen... I must get myself an old EMAX-II, some time...
I just bought Logic Express for my MacBook Pro, and I've got my Motif ES8 connected via USB. I've been trying to track down an mLAN interface, but they're no longer in production, and I don't trust eBay for this. :-/ I also need a low latency audio interface for the Mac. Any suggestions? Something that's supported on both Windows and Mac OS would be ideal, but not required. Cost is a factor, but only because I don't plan on using the interface very often; otherwise, I'd probably just buy something nice from MOTU.
If you only need a single audio in, then I recently used a "Blue Icicle" (

I have had a number of different interface over the years, but whenever I start a new project... I always go back to my Edirol FA-101... I bought it back in September 2004... and it's been my workhorse ever since... Other interfaces have come and gone, but not this one... for both studio and live work, it's built like a tank.
If I were to buy an interface today, it would be a MOTU UltraLite Mk3.
