Made this video to show drums using a HH instead of switching to crash for (BLUE) open HH notes.
Its adds a great challenge as well as teaches you to use that left foot for something.
Not all drum modules can set separate MIDI notes for open and closed HH but there are workarounds available. It is NOT a function of the MIDI Pro adapter.
Anywho, check it out, sorry for the crappy quality. :P
