Oh I see, the Amp/Arp are in the same section. Its possible to toggle between them. Its just sort of misleading the way it has been labelled in the manual. It only says Arp rather than Amp/Arp. Still the Arp section still doesn’t seem to respond to incoming CC’s when in Arp mode. Maybe I am doing something wrong? I am sequencing the OT externally too if that makes a difference. [/quote]

Amp parameters belong to audio tracks.

Arp parameters belong to MIDI tracks.

What your CC does, depends on where you send it to.
