I pretty much quantize most things, especially drums.
If I have a drum break I will use the groove from the Rexed Drum break and use that groove for everything else to make everything fit tight.
I dont use quantization when trying to emulate instruments played by a human, no human is a robot and to get a loose groove you cannot quantize.
I personally think quantization is essential most times and so is a groove. Im so happy that reason added this feature, now I can get proper grooves going on.
In a nutshell tho, this is probably one of the best improvements propellerhead made.
The thor is cool, but very complicated takes time to mess with, and its a processor hungry synth.
