Spillover
The block supports Spillover between presets.
Shimmer
The Plex Shift type and Shimmer Verb type both produce the shimmer effect. The Shimmer Verb type is a little easier to dial in (increase Shimmer Intensity), but don't overlook the power of the Plex Shift type. The Plex Shift is even a little less CPU-hungry. Check out the UNDULATOR factory preset.
The Reverb block can also create shimmer reverb effects.
Parameters
Filter
There's an adjustable filter in the block's wet signal. Filter can be any of the standard types (all types except comb filter types). Frequency, Q and Gain are modifiable.
Crossfade / Granule Length
The Cross-fade parameter has been removed.
For the Plex Detune type, the Cross-fade parameter has been renamed Granule Length.
Shimmer Intensity
This parameter is available for the Shimmer Verb only. It defaults to 4. You may get better results when increased.
Envelope follower
The Plex Delay has its own envelope follower, allowing volume swells.
The Owner's Manual recommends these settings: Threshold -70, Attack 400, Release 15.
Stack/Hold
When HOLD is activated, the wet input to the block is muted and feedback is set to infinity. This can be used to achieve pad sounds and drone notes/chords.
When set to STACK, incoming audio is stacked on existing audio and held.
Hold/Stack can be controlled with an External controller. When attaching a pedal to Off/Stack/Hold, Heel is Off, Stack is middle and Toe is Hold.
Decay Time
This is similar to the Feedback parameter in the regular Delay block.
Spread
Values beyond +/-100% increase the apparent image beyond the stereo field.
Low Cut, High Cut
FRACTAL AUDIO QUOTES
[1] When using the Plex Verb the Low Cut and High Cut are very powerful controls. For pad-like sounds try Low Cut around 250 and High Cut around 2K. Experiment with different values to create different textures.
