Chebz

Chebz is a toolbox for building waveforms out of stacked sine waves at different frequencies.

Chebyshev polynomials are used to efficiently generate the sequence of harmonics of a fundamental sine wave up to the 9th harmonic. The blend of harmonics in the output signal can then be controlled and modulated along with the overall balance of odd and even harmonics.

Modulating signals can be smoothed with three levels of smoothing (none, medium, high) to reduce clicking. The blended output signal can be optionally wave-folded, and the shape of the resulting wave form is displayed in a handy scope.

Finally, each harmonic has its own dedicated output, which can receive either the unmodulated sine wave at that frequency or the modulated harmonic (switchable via a modulation bypass switch).
