My board: Impulse 61.
Successfull connections: Impulse acts as a good MIDI interface for AKAI EWI 4000s (MIDI In/Out connected to Impulse MIDI Out/In) and an editor/librarian for the EWI runs on the Mac and reads/writes as expected. Successful MIDI Out: Impulse controls Roland XV-2020 and the aftertouch function is satisfactory.
Unsuccessful MIDI In: Yamaha WX-5 wind controller MIDI Out to Impulse MIDI In is expected to produce messages thru the Impulse and sound be produced by the XV-2020 (still connected to the Impulse MIDI Out). But the Impulse and XV do not respond to the WX-5 MIDI Out messages.
I had assumed the Impulse can act as a stand-alone MIDI device (powered by USB). But does the MIDI In need to be connected to the MIDI Out ONLY THROUGH SOFTWARE?
I'll check other connection-type solutions (try another MIDI cable, etc) and get back to you on this.
Oh yeah, the Impulse Setup says "DIN from Loc" and the Current patch says Keyboard: MIDIPort: ALL".
Why do I need to use both the Impulse and WX-5 as MIDI Controllers for the XV-2020? Because I have specially-designed patchers in the User bank that respond to Breath pressure and the aftertouch.
Is there some way to copy the MIDI In to the MIDI Out?
