32. Gen5

A Gen5 UGen can produce a wave with exponential line segments.

We have to give coefficients in range (-1 to +1), for x from 0 to 1. These serve as the y-points where the piecewise exponential curve goes through.

Since a ramp from 0 to 1 is the function of a Phasor, a phasor drives the Gen5 oscillator.

We have 2 periods of Gen5 as the phasor varies 0 to 1, for 2 periods.
