There are multiple parts throughout the Stash Mix which incorporate multichannel cross-fades and quick expressive mixes. Particularly, one of the first instances its noticeable is in the beginning of the mix with the heavy guitars and staccato vocals. This is actually three cuts of the original song mixed back and forth to create a unique sample that was then re-sampled and patched in the mix later.
In Reason however, the fader on the 14 channel mixer as well as the volume knobs on the line mixer are linear power controls. This results in a dip in the volume of each sample at the center point of the cross-fade. Obviously this is not a desired effect.
Kurt Kurasaki, the Author of
Power Tools for Reason found a great solution to this problem. As it turns out the panning knobs on the line mixer operate with equal-power. Exploiting this function, two line mixers and a Combinator can be used to create and equal-power cross-fader perfect for seamless transitions between multiple parts. The patch is a bit confusing but if you follow the details in the screenshots you'll be able to experiment and get the gist of what's going on.
