Tone Sources Section 

As monophonic analog synths go, MG-1 Plus 
is unique in that if features two standard 
mono analog oscillators (i.e., capable of 
sounding one note at a time), as well as a 
poly section that can sound up to 32 notes 
simultaneously. In this section, we'll discuss 
the mono oscillators. Note that the MG-1 
front panel refers to oscillators as "tone 
sources;" perhaps Radio Shack felt this 
would be less intimidating for consumers 
than, "oscillator." 

Sync 2>1

- This causes Tone Source One to 

force reset the start of Tone Source Two's 
waveform to the beginning of its cycle, 
resulting in a wide range of harmonic tones 
from Tone Source Two. The range of tones 
can be varied by adjusting Tone Source 
Two's 

Detune

 and 

Octave

 controls.  

Octave

- Sets the pitch range for each oscillator in octaves. 

Fine Tune (Tone Source Two only)

- This can be used to fatten up two oscillator patches by 

detuning a small amount, or for "building-in" a set interval. Its range is a smidge over a fifth, 
up or down (unless the 

Sync 2>1 

switch is on).  

Wave Shape

- These allow selection of sawtooth, square (

Tone Source One

), or pulse (

Tone 

Source Two

) waves.  

3.1

 

Master Tuning and Note Priority/Trigger Controls 

Tone Sources

- The knob at the top left of the panel acts as a master 

tuning control for both Tone Sources, with a range of just over +/- 300 
cents.
