No issue here with the Summit in Cubase 14 Pro, I just tried a quick test recording the filter cutoff (14 bit midi) and vca gain (NRPN). The synth is setup to send and recieve NRPN, all records and playback fine. No issues with weird stuff happening when operating any of the buttons on the front panel either. If I do want to go in depth with editing recorded automation with it I'd probably use Sigabort.
