Informação

The AVATAR is divided into two sections: Synthesizer and Pitch Extractor/CV Generator. The Synthesizer section is like the ARP Odyssey (in fact, the AVATAR and Odyssey use several of the same printed circuit boards). It consists of two voltage controlled oscillators, a voltage controlled filter, a voltage controlled Amplifier, two envelope generators (ADSR and AR), a low frequency oscillator, and a sample and hold circuit. As with standard Keyboard synthesizers, the Synthesizer requires a 1 V/ Octave control voltage, gate and trigger to be played. The Pitch Extractor/CV Generator translates the Guitar string signals into the language of synthesizers: 1 V/Octave control voltage, gate and trigger. Using the ARP Six Channel (Hex) pickup, the string signals are multiplexed to one output (last note played) and then transformed to a control voltage. Since the Synthesizer is monophonic (single note), only one string can be extracted and converted to a control voltage at a time.
