Tetrachords: Build a progression in 1 minute

Building a 2 track progression on the Tetrachords using an ARP track and a 3 voice Chord track. The progression is then globally transposed to a new root note while maintaining the relationships between the chord and arp line. The sound sources are the 4 voice doepfer A-111-4 and the drums are the Digitakt. The tracks of the Tetrachords are being triggered by rhythms from a trigger riot. Which is in turn clocked from the Digitakt meaning everything is synced.
