Lower Keys Sending Multiple MIDI Notes

[s16016wb]

This started all of a sudden on my Keylab 61 : C1 through G1 are sending multiple midi notes, in roughly an augmented chord.

Example:  C1 sends C1, G#1,E2, C3, G#3, E4, C5, and G#5

All of the keys from C1 to G1 send a transposition of this chord, although not all of the notes are present with each key press

When I press a pad assigned to a midi note between C1 and G1, only the correct note is sent.

Any ideas on what is happening?

thanks!

Popped the hood and reseated the ribbons... all is back to normal.
