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.

I work at a second hand shop and when I came in today I found one of these on the shelf marked for $75. I called my buddy who makes electronic music and put it on hold for him. When he came down and tested it out it sounded fantastic. He was ecstatic I found it and was able to hold it for him and he bought it right away.

Oh...HumDrum, my butt! Bass, wild sounds, Gate and trigger via a Kenton MIDI make this little guy a freaking joy in my lab. Pipe it through effects and it'll breathe life and bass into any tune.

I picked my MG-1 2 months ago and I absolutely love it, the only issue is that I need to get new slider knobs, but that's cheap. This has to be one of the funnest synths I've ever used, and it's sound is great. Classic fat moog, I l just ove it

Just because somebody puts one up on ebay for £800 many times it does not mean it is worth that ridiculous amount. Also be aware that lots of rubbish is written via these posts so that the price can be artificially inflated.

Do yourself a favour and get a Prodigy they are far superior in every way. If you really want to have the organ part mod the Prodigy to take an input to the filter and buy a kiddies toy organ to play through it and this would blow away this synth which was sold as a TOY - sadly I am old enough to remember them in Tandy (Uk version of Radio Shack).
