Recommend a USB MIDI controller for me?

[MBTC]

I have the Saffire Pro 24 which I guess is similar to the Scarlett 18i20 except FireWire instead of USB and less mic preamps (and lower cost, I think the Saffire Pro 40 would be more of a Firewire equivalent in cost and features).

Overall I have nothing but good things to say about it, only thing I would do differently if buying right now is opt for the DSP version because its not much more in cost. As you know I don't have a lot of hardware to connect so the Pro 24 might not be an option for you.

I ended up with both the audio interface and monitors I have (M-Audio BX-8 ) mostly after seeing a friend's good experience with same setup. He creates some insanely clean mixes, doing some tricky stuff with vocals and acoustic instruments too, so I figured I couldn't go too wrong, plus the setup was relatively cost effective compared to other options.
