SCI Pro One stuck in drone with gate selected

Hello! Question for anyone who had dealt with pro one keybeds, I have a peculiar defect in mine. When the gate mode is enabled the light stays on and the signal continues to drone with the amp open. When I hold down the high C, the droning stops and the light goes out and the rest of the keys can be played with accurate ADSR response. Do you think it’s just a failed keybed and the modern replacement kit would fix this? I’m currently controlling it externally but would like to regain the glide function soon. Also I can’t get the sequencer or arp to function at all. Everything else works fine
