Filter Controls
Filter Type
Click this drop-down menu to set the type of filter used in the envelope.
Filter Frequency
The middle large knob is the Filter Frequency knob, which controls the cutoff
frequency of the filter assigned to each Patch. Moving the knob counter-
clockwise closes the filter, while moving it clockwise opens the filter.
Filter Envelope
Each Patch has a built-in filter envelope, shown in the
Filter Envelope Pane. Turn the knob on its right to select
how much the filter envelope affects the sound.
Twist 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.
Filter Q (Resonance)
This knob affects the filter's resonance—the frequencies just before the cutoff
frequency set by the Filter Frequency (center) knob. The higher the setting, the
more those frequencies will be boosted.
Tip: Automating the filter cutoff while the filter's resonance is enabled is a great
way to get professional-sounding filter sweeps!
