Latch not working in 1.8.1 Mac?

Post by kdobbe » Wed Sep 25, 2019 8:32 pm

I use D-Pro with students triggering D-Pro from Logic. In previous versions, the cue would turn off when a MIDI off command happened. This does not seem to work in 1.8.1. Please advise and thanks.

Default Show Control behaviour in 1.8.1 is for Note ON to activate the button, and Note OFF to deactivate it. (I haven't tested this from Logic Pro, but that's how D-Pro reacts to Note messages from a MIDI controller)

If you enable the "Buttons latch via MIDI" option in Preferences, this ignores Note OFF messages, and toggles the button with each incoming Note ON. It's a workaround for people using MIDI controllers that don't natively support latching - I don't think it's an option you want to activate for Logic Pro control.

If you could capture the MIDI stream going from Logic to D-Pro, I can have a closer look and figure out what's going wrong.
