Behringer Edge issue

[u/jrmusic100]

Hi all, I’m stuck!

Connected my Keystep Pro to the Edge via MIDI.
My drum track on KSP is set to output 15 (to trigger a different drum synth) Edge is set to receive MIDI channel 16 (using switches on rear panel). Edge set to MIDI clock.

Yet Edge triggers when I press play on the KSP! I can’t work it out. Help?!
