I have a MIDI file example.mid
on my Mac OS X 10.6 laptop.
The laptop is connected to a MIDI keyboard (old Yamaha Clavinova, if it matters) via a Roland UM-One mk2 USB-MIDI interface. Using Apple's Audio MIDI Setup utility, I have configured the interface. Audio MIDI Setup's "Test Setup" feature will make my keyboard play notes. I can play notes on the keyboard, and have them appear in the MuseScore notation app. Thus, I think I have the laptop connected to the Clavinova correctly.
How can I make the notes in my MIDI file example.mid
play on the MIDI keyboard, via the Mac OS X 10.6 laptop? I don't want the Mac OS software to make sounds, I want the Clavinova to make the sounds. Quicktime Player and VLC generate sound themselves, so they don't seem to do what I want. I suspect I want a different kind of utility, which relays the contents of the MIDI file to the MIDI interface, for the keyboard to receive and play.
I think part of the answer will be to explain what that MIDI-relay utility is called. I see references to "sequencers" and "DAWs" in articles like Wikipedia's List of MIDI editors and sequencers, but the article doesn't really explain whether a "sequencer" or "DAW" is supposed to do what I am looking for.
