RelayDock is running in the menu bar

1. Start Cubase. Ableton Push 3 Bridge loads by itself in the MIDI Remote tab. If Cubase was already open, choose Reload Scripts in the MIDI Remote Manager.
2. Once: in Studio › Studio Setup › MIDI Port Setup, untick In ‘All MIDI Inputs’ for RelayDock and the Push’s own ports. Keep RelayDock Notes ticked: that’s the pads.

If the Cubase script couldn’t be copied into your Documents folder, copy the ableton folder from /Library/Application Support/RelayDock/Cubase Script into Documents/Steinberg/Cubase/MIDI Remote/Driver Scripts/Local.
