V \/ oct (10bit, 5Vp-p)
Output is 5Vp-p.<\/p>\n\n\n\n
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”.<\/p>\n\n\n\n
“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.<\/p>\n\n\n\n
In lower frequency it could be that some light click is heard, this is normal because the base oscillator is digital.<\/p>\n\n\n\n
