Steiner-Parker | Synthacon


The rare Steiner-Parker Synthacon is a portable 3-VCO monophonic analog synthesizer that rivals the popular Minimoog with its fat tone, durable construction and stable, stable tuning. The Synthacon has the same circuitry as the modular SynthaSystem. Interestingly, the Synthacon's filter can self-oscillate like the Minimoog, but has an opposite polarity so it doesn't lose any volume when resonance is increased as do the Minimoog and Odyssey's filters.

Each of the Synthacon's 3 oscillators can be modulated by a variety of sources: LFO, EG1, EG2, VCF, sample-and-hold, and other oscillators. White and Pink noise make for brilliant ocean/wind sounds. The filter is a multimode resonant beast switchable between high, band and lowpass filtering. It can be used to filter each of the oscillators and the noise gens. The shape of the filtering can be controlled by EG2, sample-and-hold, VCO3 or the keyboard. The voltage-controlled amp can control the oscillators, noise and filter. And there are (2) envelope generators which can control the VCA, oscillators, noise and filter.

Earlier models of the Synthacon had silver-faced front panels. Later a duophonic upgrade, the "Two Voice Synthacon" (Synthacon II) was released.

The optional 151 8 Step Sequencer could be connected through the back.

Velocity As with a piano, the harder you hit a key, the louder the sound, unlike most organs which always produce the same loudness no matter how hard you hit a key. Aftertouch Pressing a key after you activated it. Channel Aftertouch, no matter which key, it will send a Channel message. Poly Aftertouch, sends the pressure per key instead of the whole channel.
Values for OSC, LFO, Filter, Envelope are per voice unless stated otherwise.
