"The Moog Sonic 6 (also Sonic VI and Sonic Six) is a duophonic analog synthesizer that was manufactured by Moog Music from 1974 to 1979. The Sonic 6 is the result of Moog Music's acquisition of the company Musonics, which had previously made a synthesizer called the Sonic V.
The Sonic 6 is mounted in its own briefcase; the upper control panel folds and latches over the keyboard to ease transportation and storage. This feature was used by a number of synthesizer manufacturers of the time, however the Sonic 6 was Moog Music's only product that incorporated this into its design. The Sonic 6 is also the only Moog synthesizer that featured built-in speakers rather than requiring the user to use an external amplifier.
The Sonic 6 features two VCOs with changeable waveform (sawtooth, triangle, square, pulse), one low-pass VCF, a VCA, two multimode LFOs for modulation and a 49-note keyboard.
The Sonic Six is an uncommon Moog of wonderful sound and amazing versatility. It very definitely has a “discrete” analog sound, despite the fact that it is most likely an IC synth like most of the synths of the seventies. It's very warm and buzzy and reminiscent of early seventies monosynths.
The Sonic Six was based on Waytena's Musonics Sonic V. When Musonics bought Moog, they sold the Sonic V as a Moog for awhile, and then redesigned it with some castoff Minimoog case designs, and called it the Sonic Six in 1972. It was intended to be the “educational Moog” which is why everything is labeled so bizarrely. Bob Moog himself used to tote one of these around for demonstrations. It is the first non-modular duophonic synth.
The Sonic Six is a two-oscillator duophonic synth. You can set it up so that it is duophonic, (two notes at a time... one oscillator takes high-note priority and one oscillator takes low note priority), monophonic (both oscs), or monophonic with a drone (one osc changes pitch, one does not). Available waveshapes are pulse (variable), saw, and triangle. The pitch of each oscillator can be controlled by dual LFO, one by contour, and the other by the other oscillator. You can adjust the temperament of the Sonic Six, to play scales that have less than 12 notes per octave! The Sonic Six has pink or white noise available with level adjustment.
The Dual LFO is AMAZING. You have control over the balance between the two LFOs. Each LFO has saw, reverse saw, triangle, and square waves available, driven by Envelope or the master LFO slider. Having two LFOs makes a lot of modulation and triggering possibilities available.
The Sonic Six has a genuine ring modulator which allows you to choose between OSC1 and the LFO for source. The ring modulator has a mix knob, and a direct out. The ring modulator and can create more than just the standard sound. It can generate surprisingly guitar-like distortion. Audio signals can be routed through the Moog filter and ring modulator via an external input.
Ah, the contour generator. If there was one weaker spot in the Moog Sonic Six design, this is it. It is simply a modified AR envelope generator. Decay is provided by a switch, offering long or short decay. Where the contour generator becomes cool again (and perhaps cooler than most) is when it allows you to choose what triggers the envelope. You can choose between the keyboard, LFO 1, or LFO 2... or any combination. This function allows you to do many cool things... especially when you've set the LFOs to trigger the synth, and have them on different waveforms at different frequencies. If you turn down the oscillators, turn up the noise generator, and get creative with the filter settings, you can create your own analog drum machine/loop generator.
The filter is a delightfully rich Moog filter with filter cutoff, resonance, KYBD switch, Env amount, and dual-LFO amount. Having the dual LFOs control the filter is a great sound.....you can easily generate unique sample and hold type effects.
The Sonic Six has direct oscillator/ring mod out control knobs. Basically, you can add a direct line from the oscillator to the final output, which REALLY fattens up the sound. Sadly, these outputs don't go through the ENV generator, so they are always on if you have them on, but still... it is a very useful tool for effects and fattening.
The Sonic Six has “glissando” which is actually portamento. This can be assigned to both oscillators or just one, depending on the setting. The Sonic Six has a built in speaker, as well as normal output. The speaker sounds great, and has its own distinctive sound. Many mic the built in speakers! It features control voltage inputs for VCO, VCF, and VCA. Of course, it has a pitch wheel, as well."
