Hi Carol
You are obviously enjoying discovering realtime recording!!! The answer to your 1st question is Yes. You can record Performance Pads in Realtime or in Step time using the control track.
Secondly, you've got me baffled as well, because you seem to have done it correctly..... Make sure that CTL is showing above the track you recorded into. Check your control track by going into step record and there should be an asterisk where you started the performance pad (it will show you the number of the pad) and another where you stopped (if it was looped).
