Great little utility Peter

Took the liberty of abusing it

When I was a kid I remember feeding two signal generators into an
oscilloscope

So I modified yor code to do that

Add 
#declare coeff2_X = ?; // where ? is any number multiples of coeff_X work
best
and add

+ sin(2*pi*(dummy+phase_X)*coeff2_X),

to 

<sin(2*pi*(dummy+phase_X)*coeff_X) 

to get

<sin(2*pi*(dummy+phase_X)*coeff_X) + sin(2*pi*(dummy+phase_X)*coeff2_X),

Gives some amazing patterns

Have Fun
