Well, you can sketch up stuff in Krystal Engine, too. I personally still sometimes do it in EnergyXT 1.41. It's easy to sketch up stuff in anything pretty much. The problem is when it comes to making a serious project that includes many tracks and sounds, hundreds of plugins. Then Reason starts to look a bit ridiculous just like EnergyXT or whatever. Mind you, I'm not saying Reason is bad, just not adequate for a really serious project that is not some simple EDM in nature, too. Especially Reason 5. Gosh I even remember fiddling with that one, too, looong time ago. Charming program, indeed. Especially for putting down quick and simple ideas.

Personally I find it unusable for anything, really. Anything that doesn't let me draw notes freely anywhere in the project and using just "snippets" is unusable for me. I was brought up on Cubase. ;)

I'm glad you're enjoying yourself, though! Have a great time making music, mate!
