I'm on Logic, and mainly happy with it. For me, the only killer feature that would make me switch would be something like 'disable tracks' as you have in Cubase, enabling you to set up large templates without impacting RAM. The On/Off button in Logic doesn't work this way, and I would love it if it did - it's a highly requested feature for Logic. Based on the votes here so far, I just downloaded Reaper to check it out (there's a 60 day evaluation period), as it gets a lot of support outside the 2 leaders, Cubase/Logic. If I was just starting out and didn't already have Logic, I think I may have been tempted by Reaper, but now, is there a killer feature that differentiates it from Logic that should persuade me to switch over? Can it disable tracks as in Cubase for example, or are there other key features that Logic doesn't have? What am I missing? If it's just 'it's a better workflow', then while I don't disagree since I'm not familiar with it, I'm so embedded in Logic's workflow now, that that itself, at least for me, wouldn't be a reason for me to make the switch.
