Highly recommended. I'm officially a Reaper convert.
Tried cubase sx3 - liked it bar that the controls are irritating and the EQ sucks. Moved to vista premium 64, which SX3 doesnt work on so I had to change.
Tried sonar 7 producer - Powerfull software, no doubt. Very capable stuff. But its like they went out of thier way to make it as un-intuitive and non-user-friendly as possible. I have the manual (yes its a liscenced copy) and an additional guide book and tutorials, and it took me days to get to the level of familiarity and capability with this that took an hour in reaper with no assistance whatsoever.
Its powerfull, feature-loaded, very simple to setup bussing for your soundcard, load VSTs, VSTis and FX, a piece of piss to use, cheap as chips (if you choose to pay for it, which I will) and it has rendered 100s of pounds worth of liscenced DAW unused.
That its cheap doesnt factor into it - its the best I've used, full stop.
Anyone else got any experience with it? Any hints, tricks and tips? Other cool free or very cheap audio software?
