Envelope parameters
Double-click a parameter value field to enter a new value. Press Return to complete the
operation.
• Minus button (—): Highlight the modulator you want to remove, then click the button to
delete the modulator from the Modulators pane.
Note: ENV 1 can not be removed from the Modulators pane.
• + ENV button: Add an envelope to the Modulators pane. Up to five envelopes can be
used. ENV 1 is hard wired to amplitude and is always visible.
• Envelope display: Use to control your instruments over time. Drag points or lines in the
display, or drag vertically in fields, to adjust envelope parameter values.
• Envelope Type pop-up menu: Choose the envelope shape that you want to use. This
changes the appearance and available parameters shown in the envelope display. The
envelope types shown are abbreviations for the controls in the envelope shape: AR is
an envelope that provides Attack and Release controls. AHDSR provides Attack, Hold,
Decay, Sustain, and Release parameters.
• Delay field: Use to set the time before the envelope attack phase begins. This setting
is useful for sounds such as tambourines which have a noise element that precedes the
shake or hit.
• Attack handle and field: Drag horizontally to set the time it takes for the envelope to
reach the initial level. Drag the field vertically.
• Curve and field: Drag to set the shape of the envelope attack curve. Move the pointer
over the attack portion (the line) of the graphical envelope display, then drag to adjust
the curve.
• Hold handle and field: Drag horizontally to set the time that the full level is held,
following the attack phase, before the decay phase begins. Drag the field vertically.
• Decay handle and field: Drag horizontally to set the time it takes for the envelope to
fall to the sustain level, following the hold phase or the initial attack time. Drag the field
vertically.
• If the Sustain level parameter is set to its maximum value, the Decay parameter has
no effect.
• If the Sustain level is set to its minimum value, the Decay parameter defines the
duration or fade-out time of the note.
Note: If you release the key before the decay phase has finished, the envelope
moves immediately to the release phase.
• Sustain handle and field: Use to set the sustain level, which is held until you release the
key. Drag the field vertically.
• Release handle and field: Drag horizontally to set the time it takes for the envelope to
fall from the sustain level to a level of zero. Drag the field vertically.
• Vel slider: Set the sensitivity of amplitude envelope modulation in response to incoming
velocity data.
• If the Vel slider is set to zero, the envelope outputs its maximum level when you
strike the keys at any velocity.
• At a Vel slider value of 100%, the entire dynamic range is under velocity control.
