That's good to know that you can revert back to one of the older versions but, I think Presonus should have personally answered this and should also solve the problem. I started with The free Studio One Primer, then within a week (liked it so much) bought Studio One 3 Artist, then within another week bought Studio One Professional, the latest version also. So far so good, but I'm all new to DAW recording but picking it up pretty quickly but I did have a lot of questions answered by phone from the guy that sold me Studio One Pro. which Presonus want do unless you buy expensive hardware from them.(true) I think I'm gonna join a Studio One forum on FB pretty soon to be able to talk with other beginners at DAW recording that uses Presonus Studio One. Oh yeah, I bought the Presonus original FaderPort to at least have some hands on a chanell fader and transport, its very cool and motorized and does lots of things for as small and cheap as it cost me !! They changed the way the latency stuff works and that's taking me a little while to get a grip on it and I WANT record with latency period !! I was first using Presonus AudioBox USB (outdated now) and wound up with a Focusrite Scarlett 2i4 (MIDI in/out) 2nd generation (lower latency) interface and love it but man I about pulled my hair out getting it installed !! I'm sure Presonus's 2nd generation interfaces are faster also now to keep up with Studio One.......Ok I'll shut up for now lol !! Kim :-)
