Live 4 was made to be different.
The keyword here is improvise.
Unless you're recording straight up audio, you simply cannot improvise on a fly with Sonar, Cubase, Logic, or DP without having some technical difficulties.
At the same, the best solutions within Acid Pro were at best or worse....limited with just playing with loops & samples.
Sure, you can use soft studio (FLS, Orion, Project5, etc.) to fit the problems. But at that point, being technical outweigh being creative.
But with Live 4, everything is fair and balance. there is a lot of room to improvise, be creative, technical, and productive without technical difficulties.
No offence to Sonar users, but Live is easy workflow.
If you want to drop that piece in the mix, drop it right here and there. If you don't like it, take it away.
Too bad we can't do that in Sonar, Cubase, Logic, or DP.
