Program Mode and the Program Editor
Program mode is the heart of the K2500, where you select programs for performance and
editing. The K2500 is packed with great sounds, but it's also a synthesizer of truly amazing
depth and flexibility. When you're ready to start tweaking sounds, the Program Editor is the
place to start. But first there's a bit more general information about Program mode that wasn't
covered in Chapter 2. Refer to the illustration below as you read the sections that follow.

Page 2: The Program Mode Page
Program Mode and the Program Editor K2500 Program Structure K2500 Program Structure Programs are the K2500’s performance-level sound objects. They’re preset sounds that can be played on any of the 16 MIDI channels. Other synths refer to them as patches, presets, voices, multis, etc. -
Page 3: What Are These Programs In Parentheses
Program Mode and the Program Editor The Program Mode Page What are these programs in parentheses? While you are scrolling through different programs on various MIDI channels, you may occasionally see a program that is in parentheses and doesn’t make any sound. The parentheses tell you that you have selected a drum program without being on one of the drum channels. -

Page 6: Common Dsp Control Parameters
Program Mode and the Program Editor Common DSP Control Parameters Editor. (Algorithms 26-31, which use hard sync oscillation, have only four inputs; you can read about hard sync functions on page 14-51.) Each of these pages has several parameters that can modulate its related DSP function. - Page 7 Program Mode and the Program Editor Common DSP Control Parameters we mentioned above (PITCH, and F1–F4). All of the DSP functions have at least one control input, but many of them have two or even three inputs. The parameters on the various control input pages are very similar; in fact, there are six parameters that appear on almost every page.
- Page 8 Program Mode and the Program Editor Common DSP Control Parameters upward in large amounts. The oscillator waveforms can be pitched higher. Any sound can be pitched downward without limit. The primary use of the Adjust parameters (Coarse and Fine) is to offset the cumulative effects of the other parameters on the control input pages.
- Page 9 Program Mode and the Program Editor Common DSP Control Parameters Source 1 This parameter takes its value from a long list of control sources (you can find it in the Reference Guide—it’s called the Control Source list) including every MIDI control number, a host of LFOs, ASRs, envelopes and other programmable sources.
- Page 10 Program Mode and the Program Editor Program Editor—Algorithm (ALG) Page Program Editor—Algorithm (ALG) Page The ALG page is the first page you see when you enter the Program Editor. It enables you to select from among the 31 possible algorithms, and assign the DSP functions within the current algorithm.

- Page 11 Program Mode and the Program Editor Program Editor—LAYER Page Program Editor—LAYER Page Press the LAYER soft button to call up the LAYER page. Here you’ll set a number of parameters that affect the current layer’s keyboard range, attack and release characteristics, and response to various controls.
- Page 12 Program Mode and the Program Editor Program Editor—LAYER Page Pitch Bend Mode (PBMode) This determines how Pitch bend control messages will affect the current layer. A value of “All” bends all notes that are on when the Pitch bend message is generated. A value of “Key” bends only those notes whose triggers are physically on when the Pitch bend message is generated (notes held with the sustain pedal, for example, won’t bend).
- Page 13 Program Mode and the Program Editor Program Editor—LAYER Page Maximum values for the Enable parameter. .The range for each is -128-127. When the controller is at a value between the Minimum and Maximum amount, the layer will be activated or deactivated, (depending on the setting of the Enable Sense parameter).

- Page 15 Program Mode and the Program Editor Program Editor— KEYMAP Page Sample Skipping (SmpSkp) Sample skipping is a new feature in V2 K2500 software that allows for increased upward transposition of samples. By using a new sample playback algorithm, the K2500 increases the maximum playback rate of a sample from 96 Khz to a maximum of 192 Khz.
- Page 16 Program Mode and the Program Editor Program Editor— KEYMAP Page sound characteristics). The nature of the change depends on the timbre itself, so this parameter calls for experimentation. Basically, timbre shifting changes a note’s timbre by imposing different harmonic qualities onto the note. A timbre-shifted note retains its original pitch, but its harmonics are those of the same timbre at a higher or lower pitch.
- Page 17 Program Mode and the Program Editor Program Editor— PITCH Page Program Editor— PITCH Page Press the PITCH soft button, and the PITCH page will appear. These parameters adjust the pitch (playback rate) of the samples after the root has been selected by the keymap.

- Page 18 Program Mode and the Program Editor Program Editor—F1–F3 Pages Program Editor—F1–F3 Pages These pages are reached by pressing the F1, F2, and F3 soft buttons, respectively. They contain the parameters governing the three variable DSP functions in each algorithm. The pages vary depending on the DSP functions selected for the three middle DSP control inputs, represented by the downward-pointing arrows on the ALG page.
- Page 19 Program Mode and the Program Editor Program Editor—F4 AMP Page Program Editor—F4 AMP Page Press the F4 AMP soft button to call up this page, which features five of the six common DSP control parameters, in this case controlling the final amplitude of the current layer before it reaches the audio outputs.
- Page 20 Program Mode and the Program Editor Program Editor—F4 AMP Page amplitude, so with a large positive value, the amplitude will be low when you play softly. Small values decrease the range between min and max, so with a small positive value, you’ll get nearly full amplitude even with light attack velocities.
- Page 21 Program Mode and the Program Editor Program Editor—OUTPUT Page Program Editor—OUTPUT Page This page is reached by pressing the OUTPUT soft button. This is where you route the signal to the eight separate outs, and to the MIX outputs, with or without passing through the effects processor on the way.
- Page 22 Program Mode and the Program Editor Program Editor—OUTPUT Page Pair This parameter defines the Output Group of the current layer—that is, which group of audio outputs the layer uses. If the layer is assigned to Pair A, for example, its audio signal will appear at the Group A outputs.
- Page 23 Program Mode and the Program Editor Program Editor—OUTPUT Page Other OUTPUT Page Configurations The following page is for a layer with one keymap and a double-output algorithm. The U and L stand for the upper and lower wires (signal paths). You have independent control of the output parameters for each wire.
- Page 24 Program Mode and the Program Editor Program Editor—EFFECT Page Program Editor—EFFECT Page On the EFFECT page you’ll adjust the parameters that control the preset effect that the global effects processor applies to the currently selected program. Whether or not you will hear the effect that you assign on this page is determined by the settings of the FX Mode and FX Chan parameters, found in the Effects Mode;...
- Page 25 Program Mode and the Program Editor Program Editor—COMMON Page Program Editor—COMMON Page Here’s where you find six frequently-used parameters that affect the entire current program, not just the current layer. The COMMON page is reached by pressing the COMMON soft button in the Program Editor.
- Page 26 Program Mode and the Program Editor Program Editor—COMMON Page Legato Play When Legato Play is on, a note will play its attack only when all other notes have been released. This is useful for realistic instrumental sounds. Portamento This parameter is either on or off. The default value of Off means that portamento is disabled for the current program.
- Page 27 Program Mode and the Program Editor Program Editor—COMMON Page Globals This is another toggle, which affects LFO2, ASR2, and FUNs 2 and 4. When off, these four control sources are local; they affect each individual note in the layers that use them as a control source.
- Page 28 Program Mode and the Program Editor Program Editor—Amplitude Envelope (AMPENV) Page Program Editor—Amplitude Envelope (AMPENV) Page Amplitude envelopes have three sections: attack, decay, and release. The attack section determines how long each note takes to reach its assigned amplitude level after you trigger a Note On event.
- Page 29 Program Mode and the Program Editor Program Editor—Amplitude Envelope (AMPENV) Page graphic shrinks in scale as the segment times get longer. This auto-zoom feature maximizes the available display space. Try lengthening one of the segment times. The envelope graphic will stretch to fill the display from left to right.
- Page 30 Program Mode and the Program Editor Program Editor—Amplitude Envelope (AMPENV) Page you see a parameter that lets you toggle between User envelopes and the sound’s preprogrammed “natural” envelope. Loop Type There are seven different values for Loop type. A value of Off disables looping for the current layer’s amplitude envelope. Values of seg1F, seg2F, and seg3F are forward loops.
- Page 31 Program Mode and the Program Editor Program Editor—Envelopes 2 and 3 Program Editor—Envelopes 2 and 3 The K2500 offers two envelopes in addition to the amplitude envelope. Like the amplitude envelope, Envelopes 2 and 3 can be assigned like any other control source. The only difference between these two envelopes and the amplitude envelope is that Envelopes 2 and 3 can be bipolar.
- Page 32 Program Mode and the Program Editor Program Editor—Envelope Control (ENVCTL) Page Program Editor—Envelope Control (ENVCTL) Page Envelopes are control sources with outputs that evolve over time without repeating (unless you want them to). You can make the envelopes even more powerful by using envelope control. This gives you realtime control over the rates of each section of the envelopes.
- Page 33 Program Mode and the Program Editor Program Editor—Envelope Control (ENVCTL) Page you realtime control over the envelope. It is, however, a good way to adjust the natural envelopes without switching to a User envelope and trying to approximate the Natural envelope. Key Tracking This uses the MIDI note number of each key as the control input for the current layer’s corresponding envelope section.
- Page 34 Program Mode and the Program Editor Program Editor—LFO Page Program Editor—LFO Page These are low-frequency oscillators. You’ll use the LFO page to define the behavior of the two LFOs available to each layer. LFOs are periodic (repeating) control sources. The basic elements are the rate and shape, which define how frequently the LFO repeats, and the waveform of the modulation signal it generates.
- Page 35 Program Mode and the Program Editor Program Editor—LFO Page gives you an easy way to increase the vibrato rate in realtime, as you can on many acoustic instruments. LFO Shape The shape of the LFO waveform determines the nature of its effect on the signal its modulating. There are diagrams of each LFO shape in the Reference Guide;...
- Page 36 Program Mode and the Program Editor Program Editor—ASR Page Program Editor—ASR Page ASRs are three-section unipolar envelopes—attack, sustain, and release. The K2500’s ASRs can be triggered by a programmable control source, and can be delayed. ASR1 is always a local control.
- Page 37 Program Mode and the Program Editor Program Editor—FUN Page Program Editor—FUN Page “FUN” is short for “function.” The K2500’s four FUNs greatly extend the flexibility of the control sources. Each FUN accepts input from any two control sources, performs a selectable function on the two input signals, and sends the result as its output, which can be assigned like any other control source.
- Page 38 Program Mode and the Program Editor Program Editor—VTRIG Page Program Editor—VTRIG Page The velocity triggers base their operation on the attack velocity of each note you play. To use a VTRIG, you simply set its velocity level (threshold), then set it to switch on or off when your attack velocities exceed that threshold.
