Korg emx1 mod issue

I performed the tube bypass mod on the emx1 and that part of the project went great, during the mod however i must have disturbed a connection because now every pot and the arp strip have no effect on anything. All buttons in each section work fine and the large notched encoders work fine. The volume pot and tube pot work fine(tube gain just adds gain overall) but every other pot is not communicating. fxedit1,2 pitch,pan,egtime,level,speed,depth,oscedit1,2, cutoff,res,egint,drive, arp strip

any idea on where to begin checking? thanks

issue resolved - it was a small cut in the 40 pin idc ribbon. Replaced the connector after trimming the ribbon and it’s fixed.
