Hi, in version 1.4.12 there is a long delay when activated by the foot controller (FCB1010) to start recording. curiously when triggered only play continues in real time.
I had this too in my setup.
I looked at the midi preferences and there it was.
In my case CC 64 was assigned for recording a loop, but now you can choose between note on, note off and hold. It was set on start record by note off, so that's when I released the pedal. I corrected it to record by note on, saved it and now it works again like a charm.
Maybe it's that simple in your case too...
in my case, the problem is with "prime recording".
