Introducing a new Comb filter with positive/negative morphing in Rack Extension format.
Comb filters usually reshape waveforms, ending up with a signal that resembles a comb shape.
Comb filters create copies of a signal and work as a delay and filter at the same time. Small delays between copies of the signal create phase offsets and their sum builds peaks.
Filter Frequency sets the length between these peaks.
Resonance sets the strength of resonant peaks at the cutoff frequency. This results in a newly-shaped waveform, called Comb filter line.
Actual standards of Comb filters have selections of Positive and Negative modes.
Positive and Negative modes have peaks at 0Hz. Classical Comb filters normally use selected positive or negative modes, but we allow morphing of these modes at the same time. The device includes two individual Comb filters with customizable settings, which you can morph between.
Note Mode activates filter Keytracking, and help to select for the Positive & Negative peaks filters Notes, linked by note frequencies.
DoubleComb rack extension is also interesting because it includes:
- Biggest range of frequencies (from 20Hz to 25kHz) in Reason devices and Rack Extensions;
- Exclusive double-side engine: Positive and Negative modes with morphing;
- Neutral sum mode of peaks (50% of Positive/Negative morphing)
With DoubleComb you can really do more than you can do with other classic Comb filters
- Filter Keytracking
New additional NOTE mode. Selects Notes (linked to frequency) for Positive & Negative peaks filters.
Comb Filter Keytracking. In NOTE mode, filter receives incoming notes and change selected Note of the Negative & Positive peaks filters at the same time. Special display show actual octave and note shifts, when filter recieve incoming notes.
