- Thread-topic: Question for USB MIDI Support on OSX
Hello,
We were wondering if OSX supports, in the domain of USB MIDI, more than one pair of bulk in/out endpoints for a given USB MIDI interface, with each endpoint having its own external jack. We have seen that only the last endpoint in/out
pair is polled over the USB, not the first one, despite the fact that both MIDI in ports and both MIDI out ports appear at the application level.
Yes, we could more than one cable number over the same endpoint, but our question remains: is more than one endpoint pair on the same USB MIDI interface supported by OSX, with each single endpoint having its own external jack?
Any help and/or information would be much appreciated.
Thank you,
Philip Lukidis
