Moog • Rogue

The Moog Rogue could be the very definition of cheap Moog bass. It's a two-oscillator analog monosynth from Moog that, while having genuine and highly desirable Moog componentry, its design cut many corners to make this Moog's most compact and inexpensive offering of its time. In fact, the design was so simplified and streamlined that Moog licensed the design to Tandy/Radioshack who built the identical Realistic Concertmate MG-1, which was even cheaper! Incidentally the Rogue is also utilized as the Moog Taurus II Bass Synth with 1-1/2 octave bass pedals instead of the Rogue's 2-1/2 octave keyboard.
The Rogue could be considered a very scaled down version of the Prodigy (which was itself a very scaled down Minimoog) offering far fewer synthesis options and flexibility. Only two waveforms per oscillator (saw and square/rectangle) and, unlike the Prodigy, the oscillators must play the exact same waveform and pitch range, for a much more limited sonic range of synth tones. You cannot mix Sawtooth with Square/Rectangle waves on the Rogue, whereas you can on the Prodigy and Liberation. Another cutback is the single envelope generator that is shared by both the Filter and the Loudness Amp, offering just Attack, Release and a switchable Sustain mode (OFF, HALF, FULL). Still, the Rogue has a decent Moog filter with an external audio input.
Moog was definitely cutting costs with this model, making it the smallest, simplest and most basic synth in their line-up; yet still versatile and user-friendly enough to be used as the Taurus II Bass Pedal synth and an entry-level electronic tinkering Radioshack junkies music machine. To this day, the Rogue is still an inexpensive place to get good Moog sounds! It is used by Peter Gabriel, Add N To (X), 808 State, Stereolab, Mr. Oizo and KMFDM.
A surprisingly versatile machine given its limited structure, but there were inputs and ouputs at the back which enabled you to include it in effects chains as a great outboard filter, modulator or gate for any audio. I had great fun wiring into my polymoog inputs at one time - some totally amazing sounds...
The MG1 has sync on/off, no third option for contoured sync(?)
Also the MG has individual sliders for modulation VCF/VCO modulation, the Rogue has switches. The Rogue has saw, triangle and square LFOs. The MG1 has trianlge square and a random S&H type LFO. Finally the Rogue has pitch and mod wheels where the MG1 does not. They simply are not the same thing.
