"Though this bares the Realistic brand name and only has the Moog name in small print, this synth was manufactured by Moog Music in their factory and just sold at Radio Shack stores under their brand name. The circuit board has the Moog logo that you've all seen many times before (see the pictures below).

I put the Rogue name in the title because this unit was designed to be a budget version of the Rogue for the home user. The funny thing is though that it actually has a few extra features that are missing from the Rogue:

1. Indivdually switchable waveforms for each oscillator (rather than ganged on the Rogue)
2. Individually switchable octave for each osc (rather than ganged on the Rogue)
3. Ring Mod sound source (called Bell Tone)
4. Extra poly section. This is often referred to as the "crappy 'organ' sound", but it's an extra feature that can be useful.
5. Internal power supply with attached cord (the Rogue has an external power supply that has a unique connector, so replacements are difficult to come by)

The only things the Rogue has over the MG-1 are:
1. Performance wheels (the MG-1 has sliders for mod depth but no pitch bend ability).
2. Fully variable keyboard tracking (the MG-1 has off, half, full - switched)

There are a few other quirks that this unit has because of it being aimed at the home market. Many of the controls has different labels (Oscillators are called Tone Source, Attack and Decay are referred to as Rise and Fall Time, etc). It also has RCA outputs on the back. There is a 1/4" headphone output on the front which is what I'ved used and it works great. Many people mod theirs to replace the RCA with 1/4" inputs. There are two RCA inputs but they just pass the sound through uneffected so that users could play along with their record collection. Many people have modded those inputs to pass through the Filter section. MIDI can also be added to this unit by mod.

This unit is usually found for less than the Moog Rogue simply because it doesn't have the Moog logo on it. If you want that famous Moog sound for less, then get this synth! It has great features and has some serious bass to it!"
