Hi all, just installed Krellnut's US freight car sounds and they sound great, but noticed on some cars they still have the DTG "clip clop" sound mixed in when going over joints instead of the more realistic ones I hear on Feather River Canyon and Sherman Hill. (The run sounds are the same as Sherman Hill and FRC though) if that makes sense. How do I change the joint "clickety clack" sounds to sound like the ones in these routes? Thanks Jamie
