Skratchworx has a piece on an incredible turntable / crossfader / MIDI contraption that’s pretty genius.
JohnBeez is a clever chap. Being a strong and tireless proponent of Vestax’s Controller One MIDI turntable combo, his mind clearly went off on a related tangent and set about making his flight of fancy into a reality. The result is a Vestax PMC06, where the whole crossfader is mounted on a rail mechanism which itself is a MIDI pitch fader. Genius.
