This is on my wish list, unless someone can tell me where I'm missing it. When auditioning styles,
I would like to be able to make changes with the mixer (i.e. muting instruments, adjusting individual volumes etc.) while the style picker is open. It seems you have to choose a style and close the picker window before any tweaking can be done?

Dave, congrats for your first post.
I agree with you, we need the feature you are describing.

I have already posted some months ago something like you wish.
See this thread Soloing tracks in the stylepicker.

Yes, another +1 here also.

A very versatile idea, probably (hopefully?) not difficult to implement.
