Ensoniq EPS 16+ Keyboard No Aftertouch through MIDI out

Hello! Just purchased an EPS 16+ keyboard version and I don’t seem to be getting any aftertouch out of the MIDI output (either poly or channel AT). Checked all the relevant settings (Midi Controllers, Base Channel Pressure), but not seeing anything other than Midi Note In and Midi Note Out in MIDI monitor on my Mac (checked to make sure aftertouch messages weren’t being filtered out there).

Using a Roland UM-One mk2, which usually receives aftertouch messages out of the box. Any help would be appreciated.

Thanks!

What are you using to monitor your output? Are you seeing mod wheel or pitch wheel data?

Monitoring on a macbook pro using Midi Monitor. I have a Roland Um One MK2 midi to USB cable, double checked to make sure Channel and Poly aftertouch were being transmitted through a different keyboard so I don’t think it’s the monitoring/midi to usb converter.

I’m seeing Pitch Bend and Mod wheel data coming through. Is there definitely no other setting that might be preventing the aftertouch being sent out? May be a problem with the keybed itself but want to rule out other options first.
