Note Priority- Since the Tone Generators are monophonic (i.e. they can
only play one note at a time), this control determines which note will
sound if more then one key is played simultaneously.
Trigger Mode- Determines Contour Generator triggering behavior. In Retrig position, the
Contour Generator will retrigger any time a new note is played; in Legato position,
retriggering only occurs if no other keys are currently held down - this is how most vintage
monophonic analog synthesizers operate. Generally speaking Retrig mode will have a more
modern and responsive feel, and is good for insistent bass lines or percussive sounds.
Conversely, legato is useful for singing leads where you'd only want to hear the attack
portion of a sound when the first note is played - a good analogy would be plucking a guitar
string a single time, then sliding the fretting finger around to change pitches.
Master Transpose- Due to the limited range of the original instrument, we've added a
three-position transpose switch at the left of the keyboard. This affects both Tone Sources,
as well as the Poly section.


Last- This is the default voice mode. If more than one key is
pressed, the most recently struck note will always take priority.

High- If more than key is pressed, the highest note will always
sound.This how the original Realistic MG-1. Interestingly, this the
opposite of how most vintage monophonic synths work - most
are low-note priority.

Low- If more than key is pressed, the lowest note will always
sound.
