Info

Use interpolated versions of delays for modulated delays. For non-modulated (fixed time) delays non-interpolated version is normally better. H.43. Delay > Diff Delay 1p / 2p / 4p 1-point (non-interpolated)/2-point interpolated/4-point interpolated diffusion delay. T input specifies the delay time in seconds. The Dffs input sets the diffusion factor. The maximum delay time defaults to 44,100 samples which is 1sec at 44.1kHz. To adjust the time change the size of the array in the delay macro. H.44. Envelope > ADSR Generates an ADSR Envelope. A, D, R specify attack, decay and release times in seconds S specifies sustain level (range 0..1, at 1 sustain level is equal to the peak level) G gate input. Positive incoming events (re-)start the envelope. Zero or negative events close the envelope GS gate sensitivity. At zero sensitivity the envelope peak has always amplitude of 1. At sensitivity equal to one, the peak level is equal to the positive gate level. RM retrigger mode. Selects between analog/digital mode and between retrigger/legato mode. In “digital” mode the envelope always restarts from zero while in “analog” mode the envelope restarts from its current output level. In “retrigger” mode consecutive positive gate events will restart the envelope, while in “legato” mode it restarts only when the gate changes from negative/zero 176 – REAKTOR CORE
to positive. The allowed RM values are following: RM = 0 analog retrigger (default) RM = 1 analog legato RM = 2 digital retrigger RM = 3 digital legato H.45. Envelope > Env Follower Outputs a control signal which “follows” the envelope of the incoming audio signal. The A and D inputs specify the follow attack and decay time parameters in seconds. H.46. Envelope > Peak Detector Outputs the “last” peak level of the incoming audio as a control signal. The D input specifies the output level decay time parameter in seconds. H.47. EQ > 6dB LP/HP EQ 1-pole (6dB/octave) lowpass/highpass EQ. The F input specifies the cutoff frequency (in Hz) for both LP and HP outputs. H.48. EQ > 6dB LowShelf EQ 1-pole low-shelving EQ. The dB input specifies the low frequency boost in dB REAKTOR CORE – 177
