Tarus 2 setup -No Sound from Keyed or Contour

I recently acquired a Taurus 2, but having some issues with setting it up.

I have the 5 pin cabled installed in the foot pedal and sound module. . The cable looks good, no bends etc, and I even tried a more modern 5 pin cable too to try and eliminate that as an issue.

I can’t get it to work in this fashion. Depress the pedal, hear the sound, pick you foot off, the sound stops.

When I have the VCA mode to Bypass, I can hear sounds fine, but they are continuous.

If I switch to Keyed, or Contour, I hear nothing .

I am a novice, but from reading the manual, I would expect this work work.

Any thoughts on what else I could try ?
