	/* "electric wind" simple installation

	This is a simplified version of the electronics for "Electric Wind", a piece for flute and electronics.

	The basic principle of the piece is simple: two signals play in separate channels.
	Whenever their instantaneous levels match and their derivatives are within a specified range,
	they trade channels. This creates modulation patterns similar to switched tone codes, but
	directly reflecting the tuning relation of the tones and their relative amplitude.
