4 Poly Section
The original MG-1 included a rudimentary poly section that operated
independently of the Tone Sources. The good news is that it allowed
chords to be played on an otherwise mono (one-note-at-a-time) synth. The
bad news is that it was extremely limited - its only control was a single
level slider in the mixer section. It could only produce a square wave, its
octave range was fixed, and its pitch could not be modulated. As you might
guess, this made for a pretty blah poly synth experience.
With that in mind, we expanded the Poly section's capabilities considerably with a few
additions. We added a saw wave, a three-position range selector, and a modulation amount
slider in the Modulation section. This may not seem like a much, but trust us, these simple
additions make a huge difference in the Poly section's usability.
Note that the Poly section can sound a maximum of 32 simultaneous notes.
Octave- Sets the basic pitch range of the Poly section. Note that the Master Transpose
switch at the left of the keyboard also affects the Poly section range.
Wave Shape- Allows selection of sawtooth or square wave.
4.1 Master Tuning Control
Cherry Audio: Surreal MG-1 Plus User Manual
Polyphony- The second knob over at the top left of the panel acts as a
master tuning control for the Poly section with a range of just over +/-
300 cents. This is also useful for subtle chorusing/detuning of the Poly
section against the Tone Sources.
