(Note that you can not control OnTheAir Video Express with MIDI, only OnTheAir Video)
One of the lesser known features in OnTheAir Video is the MIDI control feature.OnTheAir Video’s MIDI Control allows you to assign a MIDI note to buttons and clips.
Thanks to Apple’s OSX ability to instantly detect MIDI devices attached to a system, one needs only to plug in the device and begin to use the feature immediately. The simplest way to test this feature is to start with a simple MIDI keyboard. M-Audio, Roland and a variety of manufacturers have USB keyboards that are both inexpensive and packed with options.
Enable MIDI Communications
Once the MIDI keyboard is attached to the computer, open OnTheAir Video. Then go to the MIDI preferences of OnTheAir Video
Once it is enabled, you can assign a MIDI note to either
- a clip
- a button like the play/stop/pause buttons in the playlist
Assigning a MIDI note to a clip
You can assigna MIDI note "automatically", or add a note "manually"
Assign a note automatically
- Right Click on a clip and select "Assign MIDI Note..."
- The following window will show up:
- Then simply hit a key on your MIDI device.
That's it. now if you press again that MIDI note, the clip will start playing, and continue with the standard behaviour of the playlist (if it's in chain, it will continue playing the next clip, or stop at the end if it's not in chain,...)
Assign a note manually
To assign a note manually, right-click on a clip and instead of choosing "Assign MIDI Note...", select "Configure MIDI Output Node..." and this window will show up:
Then enter manually a value for the Channel and Note.
Assign a MIDI Note to a button
Instead of doing a right click on a clip to assign a MIDI note, you can also do that on some buttons, such as the play, stop pause buttons.
Clearing MIDI Notes
To clear a MIDI note, right click on the clip or button and select "Clear MIDI Note"
- Make sure to have only unique notes for each clip, otherwise you won't know which one will start
- If you are working with the Duo or Quad versions of OnTheAir Video, and have multiple outputs on the same Mac, you can learn the same MIDI key to one clip of multiple playlists in order to start clips in sync (not frame accurate).
