3 Tone Sources Section
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
Cherry Audio: Surreal MG-1 Plus User Manual
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.
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.
