Description:
Information:
                                    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.
