AMOUNT TO FILTER:

For the filter envelope, there is a control that adjusts the amount that the filter envelope signal

modulates the filter. It has both positive and negative values. If it is set to a positive value, say

+2, The envelope will add to the Cutoff control. If it is a negative value, say –2, the envelope will

subtract from the Cutoff control.

KEYBOARD/ ON/EXTERNAL:

The Envelopes are started by a gate signal. The envelopes will sustain as long as a gate signal

is still present. When the gate is off, the release of the envelope happens. The switch labeled

Keyboard/ On/External selects whether the envelopes are triggered from the keyboard, or from a

programmable gate source. When Keyboard triggering is selected, the envelopes are triggered by

a MIDI Note On. When the switch is set for On/ external, the Envelope gate sources are set by the

programmable gate sources, in EDIT mode, called “Fil. ENV Gate SRC” and “Vol. ENV Gate SRC”.

The default for the programmable gate sources is “Env Gate Input” which defaults to “On”. In this

case the envelopes sustain at the level determined by the sustain controls. This is useful for keeping

the envelopes sustaining without holding a key down, when you want to process an external audio

signal through the filters with out using the keyboard, or create drones. This also allows separate

gate sources for the two envelopes.

RELEASE ON/OFF

The Release time of the Envelopes can be set by the Release control, or this control can be

switched off. It is switched on or off in the PANEL mode menu, or by a MIDI CC message 64 (0-

63=0ff, 64-127=on). Note that this function is actually a divider for the release time, so if the

Release control is set to 10, the release of the envelopes will not be absolutely abrupt with the

Release switched off.
