bline

To generate a series of numbers in Max that outline a sinusoidal shape, you can use the sin() function in the expr object. As the argument in the sin() function goes from 0 to 2π (6.283185), the output will be the sine of that value, going from 0 up to 1, down to -1, and back up to 0. So, by feeding a series of numbers into expr, you can generate numbers that follow that sinusoidal pattern.

This patch demonstrates the bline object, and also shows how it might be used to trigger a different transposition of a sound with every bang of a metro.
