Alternate Modulation Sources (AMS) The effects of AMS on various parameters, and example applications
• By setting AMS to Gate 1, you can make the Common LFO
reset when a note is played from a state where all notes are off.
For example, this will ensure that a filter sweep always starts
from the same place.
• You can set AMS to a controller such as M.Wheel: #01, and
use the controller when you want to reset the LFO.
