well i am kind of in the same thing at times , i do remeber in version one of the os you adjusted track length with the length dial . . .and it was actaully a pretty crazy way to do some funky stuff.I use to love doing 16step sequences and then using length dial you could shorten them in an instant , i use to tweak length and position together for mad results.Length later was change and this feature was lost and instead you have to mute steps to adjust track length – maybe in the future we will see the track length back via simple dial as it allowsd a trick of shortening track length in rapid fire which sounds fantastic live – i wont ask to much though as i am amazed at the new os and features;)……but i think the old os1 way that track l;ength was adjusted is what your after .
Cheers
