Don't know about audio latency either...but could be a bright future ahead for DIY

I've never measured the latency of the RPi, but using the CCRMA satellite linux distribution, the MIDI latency was in the range of "don't notice" to "don't care" which usually means about 20-30 ms in my case.

You can use *most* class compliant midi-usb devices with the RPi. There are lists of these things easily found online.

I've since moved on to the arduino pro mini ($3) for my MIDI controller needs and I should try to build some midi processors from them as well.
