Steiner Parker Synthacon

   (0 reviews)

Steiner Parker is proud to announce their newest synthesizer, a small, extremely versatile unit designed for live performance and also for studio use, called the Synthacon. The Synthacon's extreme versatility is realized through the use of switching to achieve function interconnections.

No patch cords are necessary to route signals and voltages from one area to another. This switching system makes it possible to achieve over 35 billion different sounding set ups, without ever turning a knob or depressing a key on a keyboard!!! A brief summary of the unit's major features is listed here.

WAVEFORMS: Sawtooth, triangle, square wave, pulse, sine wave, and two types of noise (white and pink). OSCILLATORS: Three Voltage Controlled Oscillators plus a White/Pink Noise Generator. CONTROLS: 26 knobs, 3 trimmers and 43 switches. SECTIONS: Ten; KBD/PWR, Sample and Hold, Trigger Generator, Dual Envelope Generator, Voltage Con trolled Amplifier,

Three Mode Filter, Noise Generator, VCO No. 1, VCO No. 2, VCO No. 3. OSCILLATOR RANGES: From less than 1/10 cycle per second (Hertz) to greater than 20,000 cycles per second. FILTER MODES: Low Pass, Band Pass, High Pass. FILTER CONTROLS: Resonance (Q), Frequency, Mode.

EXTERNAL INPUTS: Four-Through the Sample and Hold, Through the Keyboard, in parallel with the Trigger Generator, and direct to the Filter (control voltages only). FILTER: The three mode variable Q filter can be switched in or out separately for each sound source.

KEYBOARD: 4 octaves, 49 keys (shown), playable over 8 octave range by use of range switch. BACK PANEL OUTPUTS: DC Ground and all operating voltages, plus keyboard control voltages. These out puts can be used to run optional modules with the SYNTHACON, (such as sequencers, etc.) which are manufactured by STEINER-PARKER as well as many optional units manufactured by other companies (using special adapter cables). Back panel connectors are also provided to allow connection to an external sound source for amplifying the Synthacon's output as well as connections for all the external inputs.

The unit is portable and features a self oscillating filter that has a reverse polarity which makes the filter keep consistent volume as the resonance is increased.

Once again the Synthacon features the same electronics as the bigger SynthaSystem including white and pink noise with multiple modulation points. It also has a 49 key keyboard built in as well as various knobs, buttons, and, switches.
