A complex echo-like effect

available since version: 0.5

information

A complex echo-like effect, inspired by the classic Eventide effect of a similar name. The effect consists of a diffuser (like a mini-reverb, structurally similar to the one used in JPverb) connected in a feedback system with a long, modulated delay-line. Excels at producing spacey washes of sound. Developed as part of the DEIND project.

methods:

• reset reset to initial state
  

properties:

• @feedback Get/set amount of feedback for the delay line
  type: float
  range: 0..1
  default: 0.9
  

• @damping Get/set controls damping of high-frequencies as the delay decays. 0 is no damping, 1 is very strong damping
  type: float
  range: 0..0.99
  default: 0
  

• @delaytime Get/set approximate delay time in seconds
  type: float
  units: sec
  range: 0.001..1.45
  default: 0.2
  

• @diffusion Get/set shape of the diffusion unit. Values greater than 0.707 produce smooth exponential decay. Lower values produce a slower build-up of echoes
  type: float
  range: 0..0.99
  default: 0.5
  

• @moddepth Get/set depth of delay-line modulation. Use in combination with @modfreq to set amount of chorusing within the structure
  type: float
  range: 0..1
  default: 0.1
  

• @modfreq Get/set frequency of delay-line modulation. Use in combination with @moddepth to set amount of chorusing within the structure
  type: float
  range: 0..10
  default: 2
  

• @size Get/set size of delay-lines within the diffusion unit, producing the impression of a larger or smaller space. Values below 1 can sound quite metallic.
  type: float
  range: 0.5..3
  default: 1
  

• @drywet Get/set proportion of mix between the original (dry) and 'effected' (wet) signals. 0 - dry signal, 1 - wet.
  type: float
  range: 0..1
  default: 1
  

• @bypass Get/set bypass flag. If true: bypass 'effected' signal.
  type: bool
  default: 0
  

• @active Get/set on/off dsp processing
  type: bool
  default: 1
  

• @osc (initonly) Get/set OSC server name to listen
  type: symbol
  

• @id (initonly) Get/set OSC address id. If specified, bind all properties to /ID/fx_greyhole/PROP_NAME osc address, if empty bind to /fx_greyhole/PROP_NAME.
  type: symbol
