KDFX - A Whole New Level of Effects

KDFX (Kurzweil Digital Effects) combines new, state of the art custom Kurzweil VLSI chips with powerful DSP software algorithms offering K2600/K2661 owners the best sounding, most expressive, powerful, and creative set of effects available on the planet! KDFX is built into the K2600/2661 models.

KDFX offers over 100 effects algorithms arranged into 260 effects "presets". Presets are presented in over 150 "studio" configurations. Up to 4 separate stereo effects plus a global auxiliary stereo effect are available. KDFX also includes two separate input EQs for each of the 4 stereo (or 8 mono) buses.

Additional features include:

  • Tap Tempo support
  • Better synchronization of V.A.S.T. modulators to MIDI
  • Many effects are designed to sync to MIDI clock and/or allow you to set parameters in terms of tempo and beats

The Studio - The Heart of KDFX. At the top level of the KDFX is a new object called a Studio. A Studio is essentially a snapshot of the 16 mono (or 8 stereo) input EQs, 8 mono (or 4 stereo) bus assignments, level and panning (or balance) settings, up to 4 preset effects plus a global auxiliary effect, FX and auxiliary bus send levels, gain control of mix level, and 1/4" audio output jack assignments. In other words, the studio can be configured to process all 8 mono inputs and outputs (A/L, A/R, B/L, B/R, etc.) or, if you are working in stereo, the studio can be configured to operate as a true 4 stereo bus device; any combination in between can also be achieved.

A World of Effects - Many years of research and development have paid off! KDFX's effects are absolutely stellar in quality.

108 Effects Algorithms include:

  • Reverbs (rooms, plates, halls, booths, chambers, reverse, gated, and more)

    •

  • Choruses

  • Flangers

  • Phasors

  • Multi-tap Delays (with and without tunable resonant taps)

    •

  • Resonant Filters (LP, HP, BP, Notch, all with 50dB of resonance)

    •

  • Triggered Envelopes

  • Envelope Followers

  • Morphing Filters (48dB resonance)

    •

  • Compressors (with metering)

    •

  • Expanders (with metering)

    •

  • EQ (parametric, graphic, low/hi shelf, low/hi pass 6dB/12dB filters)

    •

  • Enhancers

  • Panners

  • Tremolos

  • Pitchers (creates pitch from a pitched or non-pitched signal)

    •

  • Stereo Simulators (widens stereo image)

    •

  • Mono to Stereo Simulators

  • Multi-Peak Resonant Comb Filters

  • Rotary Speaker Emulation

  • Tone Wheel Vibrato/Chorus Simulation

  • Distortion

  • Tube Emulation

  • Guitar Cabinet Simulators (1 X 10 open back, 1 X 12 open back, 2 X 12, 4 X 12, many of the great classics)

    •

  • Ring Modulators

  • Wave Shapers

  • Quantizer+Flanger (a special effect which can variably reduce the playback bit resolution, all the way down to 2 bits, along with Flanging)

    •

  • Laserverb(TM) (a unique specialty reverb which can create buzzy pitch effects)

    •

  • Stereo Analyzer and FX Modulation Diagnostic

  • Many Combination Algorithms (Chorus+Delay, Chorus+Reverb, Flange+Delay, etc.)

The Ultimate in Real Time Control - Kurzweil's presets offer many control parameters because we know you'll want to see just what YOU can create and explore what IS possible.

You can modulate up to 18 user selectable parameters (just about all the parameters found in a studio) in real-time from the K2500/K2600/K2661 Program or Setup, or via MIDI.

For the keyboard, the sliders control many effects parameters from program and setup mode (rack users can also take advantage of this by sending the appropriate MIDI controller numbers from their external controller).

V.A.S.T. and KDFX without Sampling!

Live Mode - now allows you to take any signal from virtually any source - analog (mono/stereo), or digital (AES-EBU, SPDIF) or ADAT¬ or TDIF¬ formats (with Kurzweil's DMTi - Digital Multi-Track interface) - and process it in real time through the entire acclaimed V.A.S.T. synthesis engine as well as the new KDFX section. And all this power is under real-time control.

Just Imagine: Choices from among 31 V.A.S.T. algorithms on your next guitar or vocal track, add killer effects on top, control everything in real time, add different effects to your sequenced parts, mix everything internally, and send it out digitally!

Kurzweil... not just pristine musical samples, powerful/flexible synthesis architecture, friendly UI and the most flexible I/O available, but now, the BEST effects and BEST effect processors available anywhere.
