Control Elements

The control range is 0% to 100%. The 2ND HARMONIC encoder is equipped with alpha-dial logic. Turning the encoder rapidly causes the values to jump in steps of 10, whereas turning the encoder slowly causes the values to proceed in single increment steps.

If the need arises to make the harmonics more audible use the DENSITY control (see DENSITY, 7) to increase their loudness.

3rd Harmonic	6	The 3RD HARMONIC encoder controls the intensity of the added
		third harmonics which are being generated above the adjusted

highpass frequency (see FREQUENCY, 3).

The third harmonics are odd harmonics which carry brilliance but also sharpness and aggressiveness. A good combination of even and odd harmonics is the key to a natural sounding top- end.

The control range is 0% to 100%. The 3RD HARMONIC encoder is equipped with alpha-dial logic. Turning the encoder rapidly causes the values to jump in steps of 10, whereas turning the encoder slowly causes the values to proceed in single increment steps.
