4–3: Amp1 EG

These parameters let you create time-varying changes in the

volume of oscillator 1.

4–3a: EG Reset

AMS (EG Reset)

This selects an AMS source to reset the EG to the start point.

For instance, you can use a tempo-synced LFO to trigger the

EG in a repeating rhythm. This reset is in addition to the

initial note-on, which always causes the EG to start.

Note: Once the Amp EG is in its Release segment, it cannot

be reset. (Otherwise, the sound might keep playing forever!)

For a list of AMS sources, see "Alternate Modulation Source

(AMS) List" on page 901.

This sets the AMS level which will trigger the EG reset.

Among other things, you can use this to adjust the exact

point in an LFO's phase at which the EG will be reset,

effectively controlling its "groove" against other rhythmic

When the threshold is positive, the EG triggers when

passing through the threshold moving upwards. When the

threshold is negative, the EG triggers when passing through

the threshold moving downwards.

Note: With some LFO shapes, and with faster LFO speeds,

the LFO may not always reach the extreme values of +99 or

-99. In this case, setting the Threshold to these values may

cause inconsistent behavior, or may mean that the EG

doesn't reset at all. If this happens, reduce the Threshold

until the EG triggers consistently.

Note-on or reset

This sets the initial volume level at note-on.

This sets the level at the end of the Attack time.

Break, short for Break Point, sets the level at the end of the

This sets the level at the end of the Slope time. Once it

reaches the Sustain level, the EG will stay there until note-

off (unless it is reset via AMS).
