Above the Envelope Display area are six Page Buttons that select the controls for the current Layer’s AMP and FILTER Envelopes and the four global MOD Envelopes which are shared by all Layers for the Part.
NOTE: The AMP and FILTER Envelopes displayed are only for the current Layer—the other Layers must be selected to see the other AMP / FILTER envelopes.
