I'm about to buy this interface I think (I've finally decided) and I just want to make sure that it will work properly with the 404 (well, I have a 303, but they use midi the same and this board is a lot more active than the 303 board. Hope you guys don't mind.)

Anyway, here it is:

It seems good because it uses the stereo ins and outs, but I just want to make sure there's not something I'm missing before I buy it.

Thanks!

looks nice
i don't think you're missing anything...you can use the MIDI to sync your 303 and also record into those inputs...get a cable with left and right RCA on one end, and left and right phono on the other and you're set
