From the project
8 Harmonic tracking oscillator
Pipes is a 14HP Eurorack module designed and made by Greenface Labs. Used in conjunction with a VCO and an 8 output CV generating module such as the Bonkulator, Pipes is a great way to set the amplitude envelopes of a tone and 7 of its harmonics. The harmonics are 1f, 2f, 3f, 4f, 5f, 6f, 7f and 8f. They are generated as square waves. Pipes features one signal input, a signal output, an output level adjustment pot, and eight CV inputs to the VCAs. The signal input level must be greater than .1Vp-p for the phase-locked loop circuits to be able to lock on. The output signal ranges from 0 to…
