Quantize Mode (Off or On)
The Quantize Mode function is only available in modulation routings 4 through 6.
When Quantize Mode is on, the modulation effect will be stepped. When off, the
effect will be smooth, or linear. Example: If you were to route the Modulation Wheel
to Pitch with an amplitude of +99, moving the Mod Wheel while the Quantize
parameter was off would cause the pitch of a held note to slide up, much the same
way it does when the Pitch Bend Wheel is used. However, moving the Mod Wheel
while the Quantize parameter was on would cause the pitch of a held note to rise in
half-step increments.
