This multi has the main elements of the classic song including drums. It uses one of Vangelis' favorite CS80 sounds for the main melody and bass, which he used a lot in the 1978 - 1984 period, a wonderful example of his expressive use of the CS80. The assignable encoder knobs are set to mainly adjust velocity and pressure sensitivity and keyboard tracking of filter cutoff. The aftertouch is set to increase the vibrato rate and, only slightly the amount. With no pressure there is a default slow/subtle vibrato (which was also one of Vangelis' signature CS80 settings).
It would be much easier doing the drum track with a dedicated plugin like Spark but programming them from scratch in Origin is a fun challenge
