I'll answer both.

Record in real time is done with the RecAud button or an external program like Audacity. Most soundcards support it. You have to set recording levels which is pretty easy.

Within the range...Each RT has a recommended range which can be found in the Memo section when selecting the RT. For example the Bossa Acoustic Bass has a tempo range of 80-105. If outside of that range, you can have problems. PG fixed the 'early start' of RTs with the last update. The early starts were occurring even within the range but the patch fixed the ones I had.
