Redux Sampler Questions

This is my first time here, and first time using any Renoise products, so I am about to install Redux Sampler demo to try it out, as I’ve only just discovered this from some Youtube tutorials that I fell upon!

It looks very good…

As a Serato Sample user, how does it compare with the timestretching and key shifting?

Can you record audio directly and destructively like an audio editor within Redux? or does it have to be imported and cut elsewhere?

Also does Redux work on MacOS 10.13.6?

Are there any Serato Sample users here, that also use Redux, as i’d like to see the differences between the two

Thank you for any help
