Module feature request - pick and choose MIDI inputs

[TommySasso]

Most of my other iOS instrument apps allow you to list all active MIDI inputs and selectively enable/disable which inputs to listen to (in addition to filtering by channel).

Module, it seems, only allows you to pick a channel.

I have a midi controller, the M-Vave SMK-37, that always sends events in parallel on two virtual inputs so unless I can get Module to only listen to one of the two, I get duplicate MIDI events. This renders the controller pretty much unusable with Module.
