U-Phoria UMC204HD : I love it!

This has become one of my favorite pieces of equipement ever. Not only it allowed me to play bass and guitar through VSTs without latency, it also allowed me to play VST drums with my electronic drum without latency, which with my previous basic Behringer USB interface was not possible. MIDI in is a very useful feature. Although my e-drum does have a USB connection, it was lnly a matter of time when the driver will get bugged and stop cooperating withy computer, which it did. MIDI in saved the situation, it works perfectly and I never had a glitch with it.

This interface is just fully packed with useful features, for a very reasonable price, and works just wonderfully. I fully reccomend it if you are considering it.
