I pulled my Concertmate MG-1 synthesizer out of storage for my next Arduino project (to be described later), only to find that it wasn’t working quite right. The MG-1 was manufactured by Moog Music for Radio Shack for their Concertmate line of casio-like keyboards. However, the MG-1 is a true Moog, somewhere.

Who played this instrument? The MG-1 did not have an external speaker.
The Polyphonic features of this synth are of particular interest as polyphony was rare in synthesizers of the time. A simple ASR attack, sustain, release envelope called ‘Contour’ can be applied to both the amp and the filter.

Here is a table highlighting some of the differences pointed out by a user between the MG-1 and Rogue. It was produced without some concerfmate Moog features, such as pitch and modulation wheels, as a cost-cutting mg1- aimed at achieving a lower price for the consumer market. When a key is released the polyphony tone for that key stops immediately.
I was afraid I’d somehow destroyed my rare CA chip, but fortunately discovered that if the switches are in intermediate positions, you don’t get any signal.
I measured the inputs to the CA with an oscilloscope and found they all seemed normal. The Contour settings can only affect Polyphony while a key cincertmate pressed due to the Polyphonic gate design.
The output goes into the master volume control, and then to the synthesizer outputs. First, the MG-1 power supply is internal, whereas on the Rogue it is an external wall wart type. I removed the circuit board, soldered in the new CA, got the switches centered just right so the circuit board could be replaced, and put it back together. All of the sound-generating features come together in a mixer allowing the levels for the two monophonic tone sources, noise, m-g1 tone and polyphony to be adjusted independently.
It is a common misconception that the Poly tones are not affected by the Contour settings. Your browser does not support the audio element. Second, both Rogue oscillators share the same waveforms and octave range selectors, whereas on the MG-1 there are separate selectors for each.
The square wave based polyphony section is described as a “cheesy organ sound”  by some, and well-used by others. This posting briefly describes how I fixed it, in case anyone else has a similar problem. The square wave based polyphony section is described concertmmate a “cheesy organ sound” by some, and well-used by others.
It is a common misconception that the Poly tones are not conxertmate by the Contour settings. The MG-1 in the Present Still, this synthesizer is sought-after as an inexpensive way to get the famed “Moog Bass” sounds. The multiple notes of polyphony feed into the single filter, giving a paraphonic result.
You need to be a member in order to leave a review. One thing to note however; the LFO cannot be used to modulate the pitch to create a vibrato of the Polyphony section. Although this cpncertmate is often erroneously described as having “less” features than its Moog siblings, the Liberation and the Rogue, there is a patch which only the MG-1 can do: In addition, the contour input showed it was picking up some crosstalk from concertmare oscillator 1 trace that runs next to it, and this was being amplified into the buzzing noise.
Unfortunately, the CA is no longer being manufactured and is hard to obtain. The input plugs are simply routed to the output plugs, and not to the synthesizer.
The rest of the modulation, including the sample-and-hold, will affect the Polyphonic Signal via the filter section. Concertmate MG-1 Production period: This is the benefit of not having the standard pitch- and mod-wheels.
Polyphony – Monophonic plus fully polyphonic divide-down organ sound. Infew electronic musical instruments had the MG-1 combination of paraphonic poly section and monophonic synthesizer in one instrument.

Polk for providing information. First, the MG-1 power supply is internal, whereas on the Rogue it is an external wall wart type.
However, the output showed a 3. The rest of the modulation, including the sample-and-hold, will affect the Polyphonic Signal via the filter section. All of the sound-generating features come together in a mixer allowing the levels for the two monophonic tone sources, noise, bell tone and polyphony to be adjusted independently.
Who Played This Instrument? Due to the fact that this keyboard was marketed to a home-keyboard crowd, cconcertmate design uses bright color graphics and a simplified terminology.
