Example of the Score for Voltage Controlled Passacaglia

If you were wondering what the players were looking at during the performance, check out an example page of the score below.

Each player is assigned to a panel on the synthesizer, except for the spatializing player, who performs on a laptop. The potentiometers on each panel that are used in the patch are assigned names (such as LFO-A-1), based on their function in effecting changes in the perceived sound of the patch. In the case of LFOs (Low Frequency Oscillators), frequency modulation was their most common use. Generally speaking, LFO 1 was very slow, used for large shapes such as glissandos, LFO 2 was medium speed, used for things like vibrato, and LFO 3 was in the audio range, and was perceived as FM distortion.

The players then look on the score as the piece progresses and adjust their parameters according to quantitative and qualitative instructions, using stopwatches for synchronization. On the color scores, numbers and a "depth of color" express the changes in parameters. These players are executing control "envelopes," in the same fashion as automated parameters in Reason or ProTools.
