it has it's restriction, but the thing it does is the hard ware emulation. So you're getting completely different perspectives when it comes to recreating things.
In theory it's all wave forms, so you should get close. but with out certain parameters or specific wave samples or types, it's tough to even get close.
I Have ableton and reason and i prefer reason because it's a great for my work flow. Plus it'[s more intuitive because i come from a world of wires.
Reason is not as precise, and it's sampling capacity is so-so, but then i know i need to get close and can fix automation in reaper and or ableton.
It's definitely a secret weapon though.
