i've had it for all of two weeks and i use it wrong (glorified tape recorder with some midi to *play and record* plug-ins, not to keep as a midi track). main reason i got it was that i upgraded my computer, so live 9 was a thing of the past (already maxed out the os as it was).
seems like it's a bit quicker for what i do (but it's also a new apple). i'm using a new trackpad and either my technique is bad or live gets confused at times. tbd. the sound engine might sound better (?).
haven't really used the new features so much, as i'm working on a few big pieces that are taking up my time/focus.
i think they probably "improved" warp, which means that it doesn't do the artifact-laden glitching that i like as easily, so i'll have to work harder at it (or revisit how i did it in the past to see if i'm remembering my methodology incorrectly). also tbd.
mostly i was commenting about the price issue. $179 for the suite upgrade seemed reasonable. might be cheaper for the lower grades when they put it on sale? (i was on the mailing list, but i also bookmarked the page to see what was what.) are you a registered user?
