Finally broke down and got the kenton midi usb host for my logidy umi3 footpedal (had been using my laptop as a midi host running through logic, works but clunky etc). The kenton is plug and play.
Next i got greedy and plugged in a usb splitter, the logidy AND both my korg nanokontrol studio and nanokey studio . all 3 work and are powered by the kenton.
The nanokontrol studio is controlling the volume on each track and the pan is controlling the low pass filter cutoff on each track, mutes etc
