MacOS IAC bus, problems?

Are there any known problems with VCV MIDI CC->CV with the macOS IAC bus?

In the classroom the other day, a student was sending CC values from Pure Data to Rack, and nothing was happening on the Rack side.

But, Pd was able to send MIDI to a DAW. So we know that MIDI was going out from Pd, and that the IAC bus was working properly with other software. Just, Rack was not receiving.

(Yes, Core MIDI and the correct name of the IAC bus were selected in the CC->CV module.)

Thanks. hjh

no, works fine here, i have used it with different source ( Usine, Bespoke)

OK… drat… everything looked fine in the classroom, but nothing…

Try again later.
