Stereo Piano ROM
The Stereo Piano ROM option adds 4 Megabytes of Stereo Piano samples to your K2500, and also enables you
to upgrade your sounds further with the 8 Megabyte Orchestral ROM and the 8 Megabyte Contemporary
ROM. The Stereo Piano Option adds objects in the 700s bank. There you will find new programs, keymaps,
samples, and a new effect - “709 Soundboard/Rvb”.
Monaural Piano Programs
Most of the new piano programs are set to play in stereo, though “780 MonoStudioGrand,” as well
as a number of programs on the accessory disk are designed for mono use. If the pianos are to be
played through a mono sound system, the best results will come from these mono programs, not
the stereo programs mixed to mono.
StretchTuning
Unless otherwise noted, piano programs are “stretch” tuned, like an acoustic piano. Since the
higher harmonics of a stretched string tend to be sharper than those of the real harmonic series,
stretch tuning ensures that the piano remains in tune with itself harmonically. Stretch tuning is
sometimes referred to as “solo” or “beat” tuning.
Keymaps with “440” as part of their name - such as “776 Mono Piano 440” offer straight (non-
stretch) tuning, where the fundamental of each note is tuned to A440. Programs that use these
keymaps (e.g., “777 Piano for Layers”) will mix better with other acoustic and electronic
instruments. This type of tuning, therefore, is sometimes known as “ensemble” tuning.
Stereo Piano ROM Programs
As shown below, the number of programs added to the 700s bank will depend on whether you
have also added the Orchestral and/or Contemporary ROM options. Contact your Young Chang
/ Kurzweil dealer if you are interested in these additional upgrades.

770 Stereo Piano Both sides of stereo image can be edited at the same time to preserve image stability.
771 Piano Left These two keymaps are the same as 770, but either side of the stereo image may be edited in-
dependently.
772 Piano Right
773 Pno440 Left
These two keymaps are non-stretched 440 tuned, for use when layering with other non-piano
keymaps so that the upper notes are in tune.
774 Pno440 Right
775 Mono Piano
This is a stretch tuned mono keymap consisting of the best quality samples from either left or
right portions of the stereo samples.
776 Mono Piano 440 This is a non-stretch tuned mono keymap consisting of the best quality samples from either
left or right portions of the stereo samples.
777 Hybrid Piano 1 This is a mono keymap consisting of samples not used in 775.
778 Way Dull Piano This keymap is specifically designed for program 786 “Way Dark Piano”.

Stereo Piano ROM Programs with Controller Assignments
This list describes how each of the Stereo Piano ROM programs can be modulated or altered by the various MIDI
controls. Only those controls which may not be immediately evident are listed. Controls such as attack velocity
and keynumber are understood to be assigned to most programs.

770 Concert Piano 1 General purpose stereo piano for solo play-
ing. Uses several layers, providing specific
filter settings and curves for different key
ranges and strike levels. Soft pedal replaces
all layers with layer 1 - voiced to emulate una
corda (u.c.) sound.
771 Studio Grand Dynamics and brightness compressed
for easy control and mixing with other
instruments. Soft pedal emulates una
corda (u.c.) sound.
772 Brt Grand & Str String Balance String Brightness
773 Stereo Solo Pno Specifically for classical solo piano, us-
ing wider dynamic range and more sus-
tained envelope. Soft pedal emulates
una corda (u.c.) sound.
774 Brt Concert Pno Similar to Concert Piano 1, but filter ve-
locity curves exaggerated for easy dy-
namics; Hard strikes very bright. Soft
pedal emulates una corda (u.c.) sound.
775 Concert Piano 2 Suitable for solo playing. Easily edited, and
may be played on a non-drum channel.
776 Soft Piano
777 Piano for Layers Import this template to other programs to
create piano combinations. Its 440 tuning
controls beating in the upper range when lay-
ered with other waveforms.
778 Rok Piano Wet/Dry Mix
779 RandomPan Grand Wet/Dry Mix The two sides of the stereo sample are
played by independent layers. Since the
layers are not synchronized, slight vari-
ations in note starts between them create
an unstable stereo image.
780 MonoStudioGrand Treble Boost Monaural sample; a hybrid of the left and
right channels of the stereo recording. Use
mono programs such as this in live perfor-
mance with mono PA systems. Soft pedal
emulates una corda (u.c.) sound.
