We are all guessing, but my guess is they simply made a mistake in the design. The issue is specific to their analog units only. Seems they missed somthing in the hardware when developing and designing the analog units.
It would be nice if they could enable it but I bought them knowing they do not offer this functionality. So much gear out there does not midi sequence externally, we should just not assume all elektron gear will do so either. They were never sold with or promised these features in the analog boxes. As I said, would still love these features if they could include them.
