Realistic Concertmate MG-1

Realistic Concertmate MG-1 Image

This is the very source of cheap Moog bass! It is a lot like the strap-on Moog Liberation in its design and architecture and also looks and sounds very much like the Moog Rogue. The MG-1 was built by Moog for Realistic (Radio Shack), and was designed specifically for the home market. Very basic and easy to use, this is a nice cheap way to get your hands on Moog sounds!

The MG-1 is a 2-VCO monophonic/polyphonic analog synth with a genuine 24dB/oct Moog filter, however the overall sound is thin. On the MG-1, the VCOs are referred to as 'Tone Generators'. It can produce sawtooth, square and pulse waveforms, and the oscillators are detunable and syncable. A simple ASR (attack, sustain, release) envelope called 'Contour' can be applied to both the amp and the filter. The LFO section provides triangle or square wave patterns as well as Sample-and-Hold. Additionally there is a simple Ring-Mod effect called 'Bell'.

Unique to the MG-1 is a slider on the far right side of the keyboard which controls the volume of a simple divide-down polyphonic organ sound. This feature makes it at least a little more versatile than the Rogue. There are RCA inputs and outputs (the input is routed straight to the output for playing along with music from your stereo system) but no external speakers as in most other home marketed synthesizers. There is also no sign of Midi or patch memory on the MG-1. It is used by Peter Gabriel, 808 State, Remy Shand, and KMFDM.

Here is a table highlighting some of the differences pointed out by a user between the MG-1 and Rogue.

Has anyone tried using a moog ep2 pedal with the mg1?

I cant seem to get mine to work. Ive tried all the inputs. The Trigger and Pitch inputs react to the pedal but dont effect the filter. However, my mg1 came with several mods, one including a VCF CV IN. That one doesnt work either. Is it a voltage issue?

Anyone have success using the expression pedal?

Wow VS, I always rely on you guys when it comes to reviews, the sound may be a ltittle slim especially around the bass, but MAN! This machine has so much hands on possibilities, I love it personally. I cant really find in the review what the argument is for rating it two stars, care to explain? I don't own one YET, but I play it very often at a mate of mine, an have borrowed it several times, thats what me me think I need to get my own one.

Thanks guys!!

I have a mg1 concertmate but mine has no reference to "realistic" written on it.
Infact it has Moog written on the back.
Is this rare? is it a prototype maybe?

VSE don't know squat about analog synths. Otherwise they wouldn't have rated this little gem at only 2 stars. 315 other people can't be wrong by giving it the 4 stars that it deserves.

Anyone who's ever played this synth knows how good it sounds, and how surprisingly versatile it really is.

Eric White and C. A. Polk should check their facts before writing a review here. The Poly section is fully polyphonic (32 notes) and not 10 "voices" as they erroneously wrote! Who the hell are those guys anyway ?
