Four independent delay lines

Sigmund is far from just another delay: it consists of four discrete delay units, each with its own, independent set of parameters. Each of the delay lines has complementary modules built in, independent from the feedback loop:

  • Multi-mode Filter (can work either in or outside of the feedback loop).
  • Overdrive module.
  • Amplitude modulator (for tremolo effects).

Sigmund has two general-purpose Modulators which can be used to auto-modulate some of the delay lines' internal parameters. There are three different modes a Modulator can operate in:

  • LFO.
  • Envelope.
  • Peak follower.

LFO and Envelope can be re-triggered by external source; MIDI notes or transients detected in input signal (configurable independently for each Modulator).

Flexible routing

Sigmund's four delay lines can be interconnected with each other in practically every manner possible. The plugin offers a choice of nine different routing topologies. For example, say you have your delays currently running in parallel but would like to have a cascade of serially connected delays instead: you can reconfigure them instantly by choosing your desired algorithm with just a click of the mouse. For even greater convenience when working with Sigmund, the output signals of each of the four delay lines are combined in a special, purpose-built internal mixer.

Intuitive design

Sigmund's user interface has been designed from the ground up to be as intuitive as possible. A convenient preset browser allows for quick auditioning of the extensive, included factory preset library. This, in combination with a novel system of 'padlocks' for locking individual sets of parameters when changing presets, allows you to zero in on the desired effect with extreme efficiency.

Multitude of purposes

Sigmund can be applied in nearly any configuration in the studio. It can be used as an insert effect for an instrument or bus channel, or as a versatile send effect with the help of a parameter lock that allows for auditioning presets without having to readjust the wet/dry mix with each new selection. The plugin can be used universally not only as a delay, but also as a:

  • Tremolo.
  • Filter.
  • Limiter.
  • Distortion.

Each of these possibilities above is a result of the direct usage of the various modules that are available in the processing path. But also indirectly, depending on parameter values, there are other possibilities, including:

  • Chorus – from small delay time values.
  • Flanger – from small delays with feedback added.
  • Spatializer – by applying delays on delay lines with different signal domains (M/S or L/R) and phase shifts between the channels.
  • Mastering / Bus dynamic processor - Setting modulators working as transient triggerable envelopes affecting signal's amplitude (volume modulation).

Sigmund features summary::

  • 4 independent delay lines, each with:
    • Multimode filter.
    • Overdrive unit.
    • Separately configured pre and delay times with optional Tempo sync.
    • Delay times down to 0.1ms.
    • Tap function for unsynchornized delay line.
    • Selectable channel mode (L+R or M+S).
    • Stereo spread.
  • High quality delay line algorithm
    • No aliasing nor artifacts.
    • 4 selectable grades of processing quality.
  • Two multi-purpose Modulators:
    • Selectable Modualtor type (1 of 3 available):

        • Tempo synchronization as an option.
      • ADHSR Envelope.
      • Peak Follower.
    • MIDI re-triggering for LFO and Envelope type modulators.
    • Transient detector for retriggering LFO and Envelope type modulators.
  • Flexible Routing (9 possible topologies).

CPU Usage is so high it freezes my FL Studio Project damn near every time I load it.

Im having the same problem in maschine on windows or OS X...

both computers are running I7's with 16gigs of RAM...
