	float bps = 60./bpm; // beats per second
	float bpmVis = tan((time*PI)/bps);
	// multiply it by PI so that tan has a regular spike every 1 instead of PI
	// divide by the beat per second so there are that many spikes per second
	bpmVis = clamp(bpmVis,0.,10.); 
	// tan goes to infinity so lets clamp it at 10
	bpmVis =  abs(bpmVis)/20.;
