Filter Envelope
Big Bang Universal Drums uses AHDSR envelopes—
Attack, Hold, Decay, Sustain, and Release. When you
send a signal through this envelope, it passes through
each of these five stages, shaping the sound.
Adjust the envelope's shape by clicking and dragging
points on the curve shown in the Envelope Pane. The five values shown under the curve are
numerical representations of the five envelope stages. You can also manually enter a value for
each envelope stage by double-clicking the number and pressing your keyboard's Enter button.
Filter Envelope Velocity
Click and drag this knob to set how much a MIDI note's velocity affects the filter
envelope. Alternatively, you can enter a value manually by double-clicking the
number under it, entering a value, and pressing your keyboard's Enter button.
Filter Envelope Depth
This knob controls how much envelope affects the signal's filter frequency. When
this knob is set to 0, the envelope is off. When it is set to 100, the envelope will
modulate the filter between its lowest and highest settings.
