Hi guys.
I guess a "key" change function could be nice in Cross. It would help a lot of time to mix two tracks. Even in Dubstep or D'n'b, that can help a lot.
It could be an effect, or I'm thinkin on two ways.
There should be a "key" mode for the pitch (along with tempo and speed modes), so you can change the key of the track with moving the pitch without changing the BPM on the track. And if you switch back to speed or tempo, this key setting will be the "0 point" for anything else.
This method can also be used with timecoding, in relative mode especially.
Or you can just put a knob saying "key" like you did in DVS, and people can have Ultimate fun with it just using this knob to tweak the track
By the way, I think it's a usefull thing.
