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.
