The ARQ96 is an incredibly niche product all things considered, but especially compared to the DX7. It's also ~10 years old rather than ~40 years old. It's a completely different beast.

Zoom released few firmware updates, but v1.x to v2.x was a very significant change. Are you using the latest version?
