Description
This electronic musical synthesizer intends for signal's design of audible range of band with a possibility to play solo musical compositions. It can be used to create audio effects if connected to the outward acoustic device.
The synthesizer can be used as a non-standart electric signal's source for scientific and educational needs.
The synthesizer consists of the following main blocks: control unit, tone generator, vibrato generator, filter, contour and output.
TONE OSCILLATOR - waveform, frequency modulation, modulation amount, impulse width modulation, harmonics, portamento, tuning, octave +1/+2. VIBRATO OSCILLATOR - waveform ("N"), frequency, 1Hz/10Hz, ON (modulation). FILTER - adjustment (cutoff), resonance, vibrato, contour on (contourosc) - attack, release, sustain, decay OUTPUT - level, on.
