I have multiple MIDI presets per song setup to transmit via Automation on song change. The presets work individualy when the transmit button is pressed from the MIDI preset list view but won't send as from the Song view by pressing the button or via automation. It appears that only the first preset sends. It worked fine before the latest update. I am using a 0.5 sec delay in MIDI settings. Has anyone else noticed this?
Sending only the first preset is the default, unless Settings > Audio & MIDI > MIDI Options > Send MIDI Presets Together is turned on. If that doesn't address your problem, please send a message from Help > Request Tech Support and answer the questions there.
