Yeah, I had a long glance at the Nord Electro5 documentation last night, camn. Killer keyboard, but I could see no mention of MIDI Clock transmit / receive, tempo, … Of course, no “standard” MIDI Implementation Chart that I could find. I guess it makes sense from an acoustic / mechanical emulation POV.
Any kind of MIDI control over Rec, Play, Stop, and other parameters would have to be via MIDI CC. Certainly possible, but the strict ‘sync’ between devices might have to be hand / foot controlled. The sources will depends on whether agordon prefers triggering the Looper on the H9, by KB control, foot pedal, etc.
