Page 9: What Is Kdfx
K2500, or from any MIDI source at all, like a sequencer or a dedicated controller. KDFX provides up to Þve individual signal effects processors. Four of these are designed to operate on their own individual buses, and the Þfth, the ÒAuxiliaryÓ processor, is designed to be global.
Page 10: Kdfx Terms
Read this chapter Þrst, and refer to it later if something isnÕt clear. Studio A Studio is the entire KDFX environment, consisting of Inputs , FX Bus es, an Aux FX Bus , FX Presets , Parameter settings, Override s, and Outputs . One Studio is current at a time in KDFX.
Page 11: Fx Algorithm (Or Just Òalgorithmó)
A speciÞc type of signal processing, like a hall reverb, plate reverb, chorus, ßanger, pitcher, compressor, rotary speaker, etc., which is at the core of an FX Preset . KDFX comes with a large variety of Algorithms, which are stored in ROM, and are not changeable by the user. Additional Algorithms, supplied by Kurzweil, can be loaded in from disk when they become available.
Page 12: Fxmode Setting
Program or Setup, a different KDFX Studio will load, and any FXMod links between that Program or Setup and the Studio will be active. If it is set to ÒMasterÓ, then the KDFX Studio must be chosen manually, and will not change when the Program or Setup changes, and FXMods in the current Program or Setup will be not be active.
Page 13: The Structure Of Kdfx
The Structure of KDFX The Studio All of KDFXÕs functions are contained in a Studio. Only one Studio is active at a time. Up to four stereo or eight mono inputs feed a Studio. The sources for these inputs are the four output pairs available on the Output pages in the K2500Õs Program and Setup Editors: A, B, C,...

Page 15: Normal Studio Structure
Many of the Studios provided in ROM follow an overall organizational plan, which uses KDFXÕs resources efÞciently and clearly. While by no means are you required to follow this structure when creating your own studios, you might want to get familiar with it, and see how KurzweilÕs own engineers have approached the issue of organization for the Studios in ROM.
Page 16 FXMod pages algorithm # (in ROM) parameters Figure 1-3. KDFX Software organization Controlling KDFX with a Sequencer A useful technique for sequencer users is to set up the Program controlling the Studio parameters to be an ÒemptyÓ program with no Keymaps but with all of the FX Mods you need in placeÑthis program produces no sound by itself, and exists only to control the Studio.
Page 17: A Tour Of Kdfx
LetÕs take a tour through several KDFX Studios. After you do this, you should have a pretty good idea of what itÕs like to work with KDFX. You will still, of course, have many questionsÑ answering them is the job of the rest of this manual.

(Beats Per Minute). Use the Alpha wheel to scroll through the many other FX Presets that come with KDFX. Like all K2500 objects, those that are in RAM (like this one) will have an asterisk in their name, and those that are in ROM will not.
Page 19: Input Editor
This is the input editor. It is showing input A, as indicated both on the left side and in the upper right cornerÑuse the Chan/Bank buttons to view the other three inputs. Input A is the ÒKDFX-AÓ stereo signal pair coming from the output of the K2500 Program Editor. In this case, itÕs our piano program.
Page 20: Auxiliary Fxbus Editor
A Tour of KDFX A Simple Studio Equalization The Þrst two blocks are the low and high EQs on the input. Put the cursor on either block and turn the Alpha wheel, and you will see the options you have available for types of EQÑthese include ÒNoneÓ, which bypasses that EQ.
Page 21: Output Editor
The Output editor page is the interface to the real world. It determines which of the signals going through the various KDFX buses show up at the K2500Õs four sets of physical outputs: A, B, C, and D. These four outputs, all stereo, go to the K2500Õs analog outputs and to the KDS digital bus.

ElecPno/Flute. This is a split keyboard program: On Layer 1, which has been assigned to the KDFX-A outputs, is an electric piano, whose key range goes up to B4. On Layer 2, which goes to the KDFX-B outputs, is a ßute, whose key range starts at C5.

Page 26: A Complex Studio With Real-Time Control
If you were previously in Master FXMode, youÕll notice that the Studio disappears from the screen. When FX Mode is set to Setup, you canÕt view the KDFX Studio except from inside the Setup. This is so you canÕt make any changes in the Studio which the Setup doesnÕt know about, which could cause all kinds of conßict and confusion.

Page 32: Donõt Forget To Save Your Studio
Building your own Static KDFX Mods Keep in mind that KDFX Mods donÕt always have to be dynamicÑthey can be used when you want to just change a few parameters in a Studio. Link the Studio with a Program or Setup. Set the Adjust values of the parameters you want to change to the new values, and set Source to OFF.

K2500Õs control sources, and can be continuously changed in real time without editing the Studio or any FX Presets. For the sake of clarity, in this chapter, we will deal with KDFX only in ÒMasterÓ mode. The issues of real-time control will be dealt with in depth in the next chapter.
Page 34 Algorithm is, there may be as many as four Parameter pages in an FX Preset. Algorithms are in the K2500 ROM, and are not normally changeable, deletable, or saveable by the user. Like ROM samples, they are simply always there. (Additional Algorithms, however, may be loaded in from disk when they become available from Kurzweil.)

If you are on a page at the EditStudio level, Compare toggles between the last-saved and current versions of the Studio.
Page 38: Exploring The Studio Parameters
|||||||||||||||||||||Wid:100%||Wid:100% <more||INPUT||FXBUS||AUXFX||OUTPUT|more> Inputs are referred to as A, B, C, and D, and correspond to the four output buses (KDFX-A through KDFX-D) from the K2500Õs VAST Program editor. These signals can be treated as stereo pairs or as individual mono signals. This is determined by the Þrst parameter on each Input page, the Mono/Stereo switch.
Page 39: Whatõs On A Program Output Bus
Input section WhatÕs on a Program output bus? There are a number of ways to determine which signals will be on the buses KDFX-A through KDFX-D coming from the Program editor. Depending on how the K2500 is set up, a Program...
Page 40: Fxbus Sends
Inside KDFX Input section FXBus sends Following the equalizers are the Insert FXBus sends. Each Input has two sends. Change the destination of each send by placing the cursor on it and doing the usual thing with the Alpha wheel and + and - keys. The FX Bus sends are stereo, and if an Input is stereo, both channels go to the send.
Page 41: Effects Buses
Figure 3-3. Width, Pan, and Balance controls A word about Gain Hard panning signals at various stages within KDFX, either for an effect or to keep individual channels isolated, can cause signiÞcant cumulative increases in gain. If this occurs, you may want to trim the levels at various stages.
Page 42: Fx Preset
The parameters on the right side of this page determine how the effected signal gets to the KDFX outputs, i.e., where the effects returns go. Each FXBus has four outputs: itself pre the FX Preset (i.e., dry); the signal post the FX Preset (i.e., the return itself); the Mix bus, where it is mixed with other Bus outputs;...
Page 43: The Auxfx Bus
Figure 3-5. Aux bus outputs About FX Presets FX Presets are where the processing takes place in KDFX. Each of the insert FXBuses and the AuxFX Bus have their own FX Preset, and they are all independent of each other, although the same FX Preset can be used on more than one FX Bus.
Page 44: Bus Overrides (Bus Mods)
PARAM2, PARAM3, etc. The parameters associated with each Algorithm are discussed in detail in Chapter 5 and in the KDFX Algorithm Reference. When you change a parameter on one of these pages, you have changed the FX Preset, and if you want the change to be permanent, you must save the FX Preset.
Page 45 Wet/Dry controls for the left and right channels. Making and Breaking Bus Overrides Some Studios supplied with KDFX, when you Þrst encounter them, have the BusMods in place, but they are not ÒengagedÓÑthat is, theyÕre not actually overriding anything, but instead simply show the values of the corresponding parameters inside the FX Preset, unchanged.
Page 46 Inside KDFX About FX Presets To engage a Bus Override, you have to use it at the FXBus level, which you do by moving the parameter away from its nominal value on the FXBus page. Try that, and then go back inside the FXPreset.
Page 47: Allocation
WhatÕs a PAU? The basic unit of signal processing in KDFX is the Processing Allocation Unit, or PAU. There are a total of 4 PAUs that can be split among the four Insert FXBuses, and another 3 PAUs for the AuxFX bus.
Page 48: Auto Allocation
Inside KDFX Allocation PAUs are normally allocated on a ÒÞrst-come, Þrst-servedÓ basis. If you set one FXBus to a PAU of Ò3Ó, then you will only be able to set the Allocation on the next Bus you set to Ò0Ó or Ò1Ó. If you then set that second Bus to Ò1Ó, then you wonÕt be able to set a value greater than 0 for any...

Page 52: Aes/Ebu Outputs
Output section AES/EBU Outputs The way the AES/EBU outputs in a K2500 with KDFX is somewhat different from the way they work in a K2500 without KDFX. The AES/EBU digital output of the K2500 (a single stereo pair) is normally in parallel to output pair A.

AES/EBU output, provided it is in ÒDirectÓ mode (as set on the SampleMode pageÑsee the previous section). If you are using the K2500 with a Kurzweil DMTi, this switch should be set to Ò16 BitÓ, since the DMTi currently operates only in 16-bit mode. However, if you are connecting the AES/EBU output to a 20-bit (or more) capable device, set the switch to Ò20 BitÓ...
Page 54: Gain Staging
KDFXÑis helpful in geting the most out of KDFX. While KDFX has plenty of headroom available for most processing, you may run into problems of digital clipping if extremely high Þlter resonances or large amounts of distortion are present on an FX Bus.

Page 57: Real-Time Control Of Kdfx
Real-time Control of KDFX KDFX Studios can be static, as we saw in the last chapter, but they donÕt have to be. One of the most powerful features of KDFX is the ability to change any of the operating parameters in a Studio in real time.
Page 58: The Kdfx Pages

Page 59: Setting Up Fxmods
Setting up FXMods Setting up FXMods The KDFX page allows three different FXMod control assignments to be made. More FXMod assignments are available on the FXMOD2, FXMOD3, and FXMOD4 pages, each of which has Þve setups. This gives a grand total of 18 Studio parameters that can be subjected to real-time control.
Page 60: Òadjustó Setting
See ÒStatic FXModsÓ later in this chapter. ÒAdjustÓ setting The Adjust setting is the starting value of the selected parameter when it is under KDFX control, similar to the Entry value of a controller in a Setup.

When youÕve chosen a Program or Setup to import a Studio from, press the Import soft button. ÒKDFX fromÉimportedÓ will ßash on the screen, and you will be returned to the Program Editor of the Program or Setup you are working on.
Page 64: Using Kdfx Live From The K2500 Keyboard
KDFX in Setup Mode If you are playing the K2500 in Setup mode, then itÕs probably a good idea to have KDFX also in Setup mode, or in Auto mode. This can help prevent confusion that can arise when mixing modes.
Page 65 Playing a Setup with a single-channel keyboard Playing Setups normally requires a multi-zoned/multichannel keyboard like the K2500 itself or a Kurzweil PC88. However, it is also possible to play Setups from a conventional, single- channel MIDI keyboard, thanks to a parameter called ÒLocal Keyboard ChannelÓ...
Page 66: Kdfx In Program Mode
Control Setups are a special type of Setup that is used only in Program mode. Although Control Setups have KDFX modulation routings in them, they are actually ignored, in favor of the KDFX modulation routings of the Program that you are using.
Page 67 Real-time Control of KDFX Using KDFX live from the K2500 keyboard Note that when you are in Setup mode, this Control Setup is ignored, in favor of the controller settings within the Setup itself. If you happen to go into MIDI mode from Setup mode, the K2500 automatically goes out of Setup mode and into Program mode, and the settings in the Control Setup on the display go into effect.

Page 70: Preventing Glitches When Changing Studios
As with any digital effects unit, you need to take some care when you are sending real-time commands to KDFX which radically alter the nature of the processing it is doing. The trickiest situations will occur when you are changing Studios, and calling up new FX Presets, Algorithms, and/or signal routings.

Page 72: Tempo-Based Control Of Kdfx
MIDI Time Code, which is used for syncing a sequencer to an audio or video tape or disk system, does not. KDFX (and the K2500 in general) responds to MIDI Timing Clocks, but not to MIDI Time Code.
Page 73: Tempo Within An Fx Preset
Tempo as an FXMod Source KDFX Algorithms that donÕt have a ÒTempoÓ parameter can also respond to tempo information, using FXMods. In the Control Source list, there is now a parameter called ÒTempo,Ó located at number 55. You can call it up quickly by pressing 5-5-Enter on the keypad, or holding down the Enter key and playing Ab below middle C on the keyboard.
Page 74: Tap Tempo
A real-time tap on a footswitch or button can also be used to control the tempo of a parameter in KDFX. Like the Tempo parameter, Tap Tempo is not KDFX-speciÞc, but can be used throughout the K2500Õs operating system, including the Sequencer.
Page 75: Kdfx In Master Mode
Sysex commands. Sysex, in fact, can be used to control KDFX regardless of the FX Mode setting, so if you need to tweak certain parameters in real time without setting up an FXMod to do it, you can use Sysex.

Page 77: Using The Algorithms
Algorithms may not have some of the parameters described here for their category. A more complete reference, with every Algorithm and the meaning and range of every Parameter, arranged in the order they appear on the screen, can be found in the KDFX Algorithm Reference.
Page 78: General Parameters
In Gain sets the level of the signal coming into the FXPreset from the Input page. As with most Gain controls in KDFX, the range is -79.0 dB to 24.0 dB, and there is an ÒOffÒ position. 0.0 dB is unity gain.
Page 79: Reverbs
InÞnDecay, when turned ÒOnÓ, causes the reverb tail to decay indeÞnitely. When itÕs ÒOffÓ, the decay time is determined by the ÒRvrb TimeÓ or ÒLateRvbTimÓ parameters. This is a good parameter to use under KDFX control with a footswitch. Wet Bal (Wet Balance). Some reverb Algorithms are actually two stereo reverbs in one, with each one receiving a different mono signal.
Page 80: Delays
DelayScale lets you change the lengths of all the taps together. Its range is 0 to 10x. Note that it is possible for KDFX to run out of delay memory with over-generous settings of DelayScale or very slow Tempos. Some Delay Algorithms will simply go to a maximum value and stay there, while in some, a calculation is made that automatically cuts the delay times in half, thereby maintaining a relationship with tempo.
Page 81: Equalizers (Eq)
Tap n PtAmt adjusts the intensity of the comb Þlter at each output tap. Range is 0 to 100%. Equalizers (EQ) KDFX has both Graphic and Parametric EQ Algorithms. Parametric EQ sections are also found on a number of combination Algorithms.
Page 82: Eq Morpher
Þlter #2 moves to B Þlter #2, and so on. Range is 0 to 100%. Compressors, Expanders, and Gates A wide range of Compression and Expansion effects is available in KDFX. The various Algorithms include different combinations of: compressor with soft-knee characteristicÑthe compression action comes in gradually as ¥...
Page 83: Expansion
Using the Algorithms Compressors, Expanders, and Gates Threshold is the level in dBFS (decibels relative to full scale) above which the signal begins to be compressed. Adjustable from -79.0 to 0 dB. MakeUpGain allows additional output gain to compensate for gain reduction in the compressor.
Page 84: Chorus
Using the Algorithms Chorus Super Gate Super Gate is a more sophisticated gate that includes these two functions: Env Time is the amount of time it takes for the sidechain signal envelope to drop below the threshold. If this time is too short, the gate can close and open too quickly from amplitude modulation in the sidechain signal.
Page 85: Flanger
Þlter. In KDFX, the ßanger is a multi-tap delay line, all (but one) of whose taps can have their lengths modulated up and down by a low frequency oscillator (LFO). The rate of the LFO is expressed in Tempo (see Chapter 4).
Page 86: Filters
When it is set to zero, the Algorithm acts like a simple delay. Range is 0 to 100%. Filters There are four types of Resonant Filter Algorithms in KDFX. All of them have these parameters in common: Filter Type (or FiltType) can be Lowpass, Highpass, Bandpass, or Notch (band-cut).
Page 87: Lfo Filter
Range is 0 to 100%. Distortion Distortion Algorithms on KDFX may also include a parametric equalizer or a cabinet simulator. Dist Drive applies a boost to the input signal to overdrive the distortion algorithm into soft clipping.
Page 88: Polydistort
Using the Algorithms Rotating Speakers Cab Preset selects from eight cabinet simulations which have been created based on measurements of real guitar ampliÞer cabinets. The presets are: Basic, Lead 12, 2x12, Open 12, Open 10, 4x12, Hot 2x12, and Hot 12. Cab Bypass switches on and off the cabinet-simulation part of the algorithm.
Page 89: Vibrato/Chorus
Using the Algorithms Tremolo and AutoPan Lo Rate and Hi Rate are the rotation rates of the rotating woofer and tweeter. Each driver woofer can rotate clockwise or counter-clockwise, which is determined by the sign of this parameter: assuming the microphones are positioned in front of the driver and the microphones are panned positively (positive numbers go to the right), then a positive value for this parameter causes the driver to spin clockwise when viewed from the top.
Page 90: Pitcher
Odd Wts, Pair Wts, Quartr Wts, Half Wts are parameters that control the shape of the frequency response of Pitcher. An exact description of what each one does is, unfortunately, impossible, since there is a great deal of interaction between them. For more information and examples, see the KDFX Algorithm Reference. 5-14...
Page 91: Ring Modulation
Ring modulation multiplies two signals (the ÒcarrierÓ and the ÒmodulatorÓ) together to produce unusual, often non-harmonic, overtones. The Ring Modulator Algorithm in KDFX has two modes: ÒL*RÓ in which two mono signals are modulated together; and ÒOscÓ, in which the input is stereo, and it is modulated with the sum of Þve waveforms that are generated from...
Page 92: Stereo Simulation
Using the Algorithms Stereo Simulation Stereo Simulation The Mono to Stereo Algorithm converts a monaural input to simulated stereo output. In Select selects the input signal to be Òstereo-izedÓ. It can be Left, Right, or both: (L+R)/2. CenterGain is the level of the summed left and right channels. Range is Off/-79.0 to 24.0 dB. Diff Gain is the level of the difference signal produced, which is the spatial component of the stereo signal.
Page 93: Fxmod Diagnostic
Using the Algorithms FXMod Diagnostic FXMod Diagnostic This Algorithm allows you to view the current levels of any data sliders, MIDI controls, switches, or internally generated VAST LFOs, ASRs, FUNs, etc. which are available as modulation sources. It has no effect on any signal being routed through it. Up to eight modulation sources may be monitored simultaneously.

Special Topics Live Mode One of the most exciting aspects of KDFX is that its use is not restricted to sounds coming from the K2500. If you have the Sampling Option installed in your K2500, then you can also use KDFX with any external sound sources using the K2500Õs ÒLive ModeÓ...
Page 96: Some Ideas For Using Live Mode
Live Mode brings that concept to digital synthesis, and lets you use all of the power of the K2500 and KDFX on any kind of input signal. For starters, you can simply hook up a CD player to the K2500Õs sampling input, get a bunch of your favorite CDs, and start fooling around.
Page 97 Special Topics Live Mode Sometimes you can hear the snaps back and forth when the LFOs and the buffers get out of sync. You might be able to smooth out the rough spots by making another layer with no pitch alterations, and crossfading between the layers: Duplicate the layer ¥...
Page 98 If the input signal is mono, you might be able to overcome this by using a delay line to ÒholdÓ the signal. The delay line could be part of KDFX, or it could be an external device, but either way its output is sent back to the K2500 through the unused Live Mode input channel.
Page 99 Mode fans. We will also be putting information about Live Mode on our Website: www.youngchang.com. Live Mode is opening a whole new era in synthesis and signal processing, and we, the Kurzweil engineers and musicians, look forward to working with you to develop its possibilities.
Page 100: Song Mode
Program, not a Setup, because the sequencer doesnÕt know how to play Setups. Since all of the KDFX Mods were part of the Setup, even though the data on the track is being played back, itÕs not being sent to KDFX (although it might be affecting the Program on the track), and so no KDFX Mods are being played.
Page 101 Studios and Songs in Master Mode When you are using KDFX in Master FX mode, the Studio does not get saved with the Song, since it is not a dependent object of the Song, or of anything in it. Therefore, if you want to...

Algorithms are 779 and 780, respectively. Using the Internal Effects The original Internal Effects processor on the K2500 is in the signal chain after the KDFX Studio. It is only connected to the ÒMixÓ analog physical outputs (not to be confused with KDFXÕs Mix bus output).
Page 103: Getting The Effects Onto The Aes/Ebu Digital Output
Special Topics Using the Internal Effects Getting the Effects onto the AES/EBU digital output Although normally the AES/EBU output does not carry the signal from the internal Effects processor, there is a way to get it to do so. This is useful when you want to record the K2500 digitally, and want to use the internal Effects.

Page 155: System Exclusive Control Of Kdfx Parameters
Appendix C System Exclusive Control of KDFX Parameters Any KDFX parameter that can be assigned to an FXMod can also be controlled by MIDI system exclusive ("Sysex") commands. Controlling KDFX parameters using Sysex can be more complicated than programming an FXMod, but allows more ßexibility. ItÕs especially useful when the K2500 is in Master effects mode, and it is also a way to use additional real-time control above the 18 FXMods that are allowed in a given Program or Setup.
Page 156: Parameters
The same example in decimal reads: 240, 7, 0, 120, 27, 42, 0, 0, 50, 247 Under Sysex control, KDFX parameter values are not mapped through display tables, but instead are handled as ÒrawÓ numbers. So while on the K2500Õs LCD you might set ÒRoomTypeÓ...

System Exclusive Control of KDFX Parameters Here are some examples of parameter values encoded into LSB and MSB: Parameter value hexadecimal (decimal) 00FF 00C8 0080 007F 0000 FFFF FFCE -128 FF80 While this may seem complex, if you are using a dedicated controller to generate Sysex, you may not need to worry about encoding parameter values, because the controller will do it for you.
