Most people (most) who buy a controller want the simplest and most automated use, a modern digital Turntable. A plus would be (if possible) to open up the jogs for some mapping, or just update the S4 jogs with more effects and abilities (maybe in the S4 preference area?) My suggestions would be... Auto TT sync mode. Enable Cues. Smooth stop speeds (fast, medium, slow) Also add some auto scratching techniques but those would need to added in the mapping area and selected with another midi source or custom S4 mapping. It seems like a lot to ask, but really, why not. The jogs are the main selling point on the S4MK3, right? Also adding a choice for the 2 led rings and deck colors would be so cool. I would choose Hulk (purple and green). Another simple addition to preferences for that. Even a limit of maybe 3 or four combinations would be fun.
