Project Notes

This is a first try at building an automatic conductor for improvising musicians.

It simply displays vertical lines, which move across the screen at random intervals. When the line arrives at "now," the musicians are supposed to change what they are doing. The rest of the time, they improvise repeating patterns or grooves. The solid line means everyone has to change; dotted line means it is optional.

The sliders let you change a few parameters. the duration divisor lets you make the durations between lines faster (the durations are actually chosen from a list, and they are meant to be used in performance with a divisor of one). The movement speed is just the speed of the lines. The dotted percentage controls how often the line is dotted versus solid.
