I’m wondering how I can receive MIDI Pitch Wheel / Pitch Bend messages.
I wired up a Receive MIDI Events node. I hooked up all available outputs (receivedNote, receivedController) to a console message via Get MIDI (Note, Controller) Values nodes, text appending along the way so I can see what I’m getting. I see the Note messages output fine, and I see the Controller messages output fine, but I do not see the Pitch Wheel messages.
I started up a freeware app called MIDI Monitor, and I see the Pitch Wheel messages there. If I remember properly from the MIDI spec, Pitch Wheel is sent as a combination of two adjacent controllers, course and fine.
Is there anything I can do in Vuo to receive the pitch bend messages? Failing that, can you think of any way external to Vuo that I could somehow transform them into something Vuo recognizes?
You’re correct that MIDI Pitch Wheel messages consist of coarse and fine 7-bit parts, but they are not encoded as Custom Controller messages; they are their own event class. Vuo doesn’t yet support the Pitch Wheel event class, but it’s on our to-do list.
In the meantime, you can use the MidiPipe freeware app to convert:
Run the Audio MIDI Setup app (in Applications > Utilities), open the MIDI Studio window, select IAC Driver, make sure there’s at least one port (click the + to add one if there isn’t), and make sure “Device is online” is checked.
Download, install, and run MidiPipe
Under the Tools section:
double-click “Midi In”, and select your input device
double-click “Message Converter”, select Pitch Wheel on the left and Control Change on the right, and select the controller number you’d like to use
double-click “Midi Out”, and select the IAC bus as output
In Vuo, use the IAC bus as input, and you should get your pitch wheel messages via the receivedController port
In Vuo 1.0.0, we added MIDI Pitch Bend support — Vuo now can natively send and receive those messages. We also added a Pitch Bend port to the Convert Note to Frequency node, to facilitate using it for audio synthesis.
