Narrative:

After pushback from the gate, ground was called and clearance to taxi to runway 7R was received. I taxied via txwys K, east, a to runway 7R. Halfway to the runway I was switched to another frequency which was the tower supervisor who gave us a phone number to call. After arrival in cvg I called. Supervisor was concerned about my choice of taxi route to runway 7R. Since he thought I was instructed to txwys B, a to runway 7R. I explained how I wanted to avoid ramp congestion so I took txwys K, east, a and neither the first officer or I heard the controller say taxiway B to runway 7R. Further discussion of diligence in listening to radio calls and following taxi instructions occurred with the conversation ending on a positive note by both parties. Supplemental information from acn 467369: given clearance to taxi. 'Taxi to runway 7R' I repeated the clearance. Captain taxied to 'taxiway B' then I asked why he was going to txwys K, east, a' to go to runway 7R. He wanted to avoid the aircraft on the ramp near taxiway B and had been given that specific routing all other times in mke. 'Txwys, K, east, a' parallels taxiway B and at some point you need to leave taxiway B to get to taxiway a anyway. Ground controller pointed out traffic on taxiway T exiting the runway and asked them to wait for us to clear. Captain relayed that the ground controller specifically told us to use taxiway B. We disagreed. Controller was asked about a review of the tape but did not respond to the captain's question. Controller stated other things to the captain and then said it was only fact finding due to numerous problems in mke.
