AVCO

Description

Additive or harmonics VCO Power supply:29mA knob1: fundamental frequency knob2: harmonics gain knob3: harmonics spectrum CV1: harmonics gain CV2: harmonics spectrum V / oct (10bit, 5Vp-p) Output is 5Vp-p. Outputs the fundamental tone and seven overtones. Both waveforms are sine waves. The fundamental tone is controlled by V / oct. The spectrum, that is, how many harmonics to add, is controlled by “harmonics spectrum”. Since the added overtones are integral multiples of the fundamental tone, it becomes a musical tone. The fundamental and harmonic gains are controlled by “harmonics gain”. “harmonics spectrum” and “harmonics gain” cannot be set to arbitrary values. It has a wave table-like format that refers to the values ??stored in the table in advance. With a combination of 256 types of spectra and 256 types of gain, you can create an infinite number of tones. In lower frequency it could be that some light click is heard, this is normal because the base oscillator is digital.
