Disklavier Controlled by Nord Modular G2

Palle Dahlstedt's Circle Self - a live feedback algorithm for Disklavier

According to Palle the "G2 does it all - essentially it is a modular synth (the G2) generating sequence patterns for a player piano based on a seed from a human player (me). No other equipment involved."

"A quick pre-concert test of the 'piece' Circle Self, for Disklavier and electronics. The underlying engine consist of four virtual musicians who listen to each other in an intricate feedback system (hence, "Circle"). All paramers are controlled from a keyboard, through a dynamic vector mapping. But the keybaord output is here fed back to the system, through this vector mapping, so the whole system is essentially playing itself (hence, "Self"). It needs to be triggered by a manual seed to get going, though.

This is the third piece in the Circle series. The previous two are:

Circle Squared (the virtual musicians are controlled by a musician using expressive pressure pads)

Circle Keys (the virtual musicians are controlled by, and interacted with through the actual piano keyboard)

The system is programmed by Palle Dahlstedt, and it is part of the research project Creative Performance. Recorded in the Sjöström Hall of the Academy of Music and Drama, University of Gothenburg, Sweden. The Disklavier belongs to the academy's department for electronic music, the Lindblad Studios."
