The first thing I do is record the audio from the multiple outs, obviously after setting up a beat. This way I can just use Audio tracks in Pro Tools and dump the Spark plug in. It's a hungry insert, I have 12 tracks of 1073 UAD EQ and 5 tracks of LA2A as well as other reverbs and other UAD processing. But, it's spark that moans when inserted into a channel. Hence I try and make it inactive as soon as I possibly can.
I wouldn't want a 'follow song' addition in Spark for many reasons, i'd be too preoccupied that Pro Tools would crash with the spark insert on a track.
I love my spark, it sounds great and is very easy to get beats going. It's a cool live tool and great in the studio, but it's not a very good plug in. You just have to learn it's limitation and focus on it's strengths
