Introduction
Welcome!
Congratulations, and thanks for purchasing a Kurzweil/Young Chang K2500 Series
instrument. Whether you’ve just gotten a K2500 (illustrated below), the 88-note K2500X, or the
rack-mountable K2500R, you’ve got your hands on an extremely capable musical instrument.
The K2500 Series instruments are packed with great acoustic, electric, and synth sounds—
combined with some of the most advanced synthesis features available, which you can use to
create almost any sound imaginable. If you liked the award-winning K2000, you’ll love the
K2500!
This manual and the accompanying
Reference Guide
, as well as the video tutorial, will get you
started with your new instrument. You’ll definitely want to keep the manuals handy as you
become an advanced user, too.
For K2500R Owners
Throughout the
Performance Guide
and
Reference Guide
we’ve simplified things by saying just
"K2500" any time we’re referring to features that are common to all instruments in the K2500
Series. Obviously, though, there are some differences between the rack and keyboard models;
we’ll point them out where they occur and mark them with a handy K2500R margin symbol
such as the one to the left of this paragraph.

Introduction
Overview of the K2500
1-2
Overview of the K2500
The K2500 has been designed to be a versatile instrument both for performance, and for multi-
timbral sequencing and recording. Its Variable Architecture Synthesis Technology lets you
build sounds from realistic instrumental samples and sampled synth waveforms—then modify
the nature of those sounds through a dazzling array of digital signal processing (DSP)
functions. The K2500 also generates its own synth waveforms, which can be combined with the
samples or used on their own. The K2500 packs 8 Megabytes of on-board sound ROM, and you
can load samples from disk into optional sample RAM.
Before we get into explaining Variable Architecture Synthesis, here are a few of the features that
by themselves make the K2500 an impressive stage and studio machine. It’s fully multi-
timbral—different programs can be played on each MIDI channel. It’s 48-note polyphonic, for a
full sound no matter how many chords you play. There’s an on-board digital effects processor,
providing up to four simultaneous effects, including realtime effects control, internally or via
MIDI.
In addition to the standard stereo audio output pair, there are eight separate outputs that can be
configured as stereo pairs, or as individual mono outputs. You can also use the separate outputs
as insert points for outboard gear.
The K2500 offers eight SIMM sockets (single, in-line memory modules) so you can add optional
sample RAM, where you can store samples that you’ve loaded from disk. You can add up to
128 megabytes of sample RAM! (Sample RAM is not battery-backed, so RAM samples are
erased from memory when you power down.)
For offline storage, there’s also a floppy drive and two
SCSI
ports, so you can store files on
floppies or on an external hard disk or load them from a CD-ROM drive. The two SCSI ports
make it easy to chain multiple SCSI devices together. There’s also provision for an internal SCSI
hard disk. You’ll find all this storage potential extremely useful for saving and loading samples,
which can be transferred to and from the K2500 using the standard MIDI sample transfer
format, or the new, faster, parallel SMDI sample transfer format (SCSI Musical Data
Interchange). See the
Reference Guide
for information about MIDI and SMDI sample transfers.
The K2500’s battery-backed RAM will store about 400 of your own programs, or 30,000 notes
recorded in the sequencer. This sequencer (Song mode) lets you play back MIDI type 0
sequences, record and play back your own songs, and record multi-timbral sequences received
via MIDI. For more onboard storage you can add the P/RAM option, which will increase your
battery-backed RAM to about 1250K, enough to store hundreds of additional programs, setups,
songs, and other
objects
.
The Local Keyboard Channel feature enables you to use the K2500’s tri-zone setups even if
your MIDI controller can transmit on only one channel. The K2500 will also rechannelize
incoming MIDI information and send it to its MIDI Out port, enabling you to control additional
synths on three different channels.
An optional sampling feature is available, allowing you to make your own mono or stereo
samples using analog or digital inputs.
And, of course, there’s the incomparable Kurzweil sound. The K2500 comes to you with 200
preset factory programs (called patches, presets, voices, etc. on other synths), as well as 100
multi-zone performance setups. Play them straight from the box, tweak them in any number of
ways, or develop your own programs from scratch—which brings us back to the powerful
programming capabilities of the K2500.

What is VAST?

What is VAST?
Variable Architecture Synthesis
gives the K2500 its unprecedented flexibility. While many other
synthesizers offer a fixed set of
DSP
tools (typically filtering, pitch, and amplitude modulation)
the K2500’s Variable Architecture lets you arrange a combination of any five DSP functions
from a long list of choices. The functions you choose define the type of synthesis you use.
Each layer of every program has its own DSP architecture, what we call an
algorithm
. Within
each algorithm, you can select from a variety of DSP functions. Each function can be
independently controlled by a variety of sources including LFOs, ASRs, envelopes, a set of
unique programmable functions (FUNs), as well as any MIDI control message. The many
different DSP functions and the wealth of independent control sources give you an extremely
flexible, truly vast collection of tools for sound creation and modification.
How the K2500 Works
The K2500 integrates two MIDI-driven components: a sound engine, and a global effects
processor. The sound engine responds to the MIDI events generated by your MIDI controller
and turns them into sounds that are processed within the variable architecture of the
algorithms. The resulting sound can then be routed through the effects processor and to the
MIX or separate audio outputs.

How to use this manual

How to use this manual
This manual includes the following:
•
how to connect and power up your K2500, getting around the front panel, and a brief
description of the operating modes.
•
basic editing, including the normal operations of each operating mode.
•
the advanced programming features that make the K2500 so powerful—a number of
familiar synthesis tools and quite a few new ones.
Even if you’re a complete techie, you should read Chapter 3, User Interface Basics. Here you’ll
get a tour of the K2500’s front panel and learn how to navigate through the major functions.
Chapter 4 describes the concept and operation of the K2500’s eight operating modes, with a
brief description of each. Chapters 6 through 13 describe each mode in detail, including the
editors contained within them. Chapters 14 through 17 discuss the advanced editing features.
Chapter 18 shows you how to use the multiple audio outputs to suit your needs. Chapter 19 is
a programming tutorial, giving you specific examples of many of the K2500’s programming
functions. Some are basic, some are advanced. By working through the tutorials, you’ll become
familiar with many synthesis techniques, and you’ll get a first-hand look at how to unleash the
power of the K2500.
When manual text appears in boldface italic (
like this
), you’ll find it described in the Glossary
in the
Reference Guide
. Only the first one or two occurrences of these words are highlighted.
The best way to read this manual is with your K2500 in front of you. By trying the examples we
give to illustrate various functions, you can get a quick understanding of the basics, then move
on to the more advanced features.
If you like to figure out your equipment for yourself, and normally use manuals only as
reference sources, you’ll probably get the most use out of the
Reference Guide
that accompanies
this manual, which contains brief descriptions of the K2500’s major operating features, and all
sorts of useful lists—
programs
,
keymaps
,
algorithms
, effects,
control sources
, and more. A
glossary and complete specifications for the K2500 are also included in the
Reference Guide.
