In earlier versions of Reason I could replace the notes in loop recording mode (not overdub). Now, in ver.6,5 I can only overdub new notes. Imagine, that I play live via Reason in loop with maybe 4 bars, I have drums -1st track, 2nd track - bass, 3rd track - chords and so on. Everything plays, I switch to track 2 (with mapped keyboard) and with mapped keyboard I turn on recording (I want a new bass line) BUT! Old bass line is still there and the same with other tracks. I note: I'm playing live, I have no time to click with the mouse and select "new overdub Line" or "alt.Line". I can't find recording mode that enables me to replace the old notes with new. Is it Possible?
(Sorry for my english)
