Disk Contents
Your SD Piano option kit comes with four floppy disks, from which you’ll install operating system
software, base ROM object files (for the standard factory programs), and SD Piano ROM object files.
Depending on the other ROM options you have (if any), you may also need to install other ROM object
files—one for each option that you have.
All of these object files are included with this kit, for your convenience. There are also two files that
contain customized programs and demo songs using the SD Piano. If you like, you can load these files
into RAM, using Disk mode (the other files are to be installed in ROM using the boot loader, as described
in the installation instructions that came with your SD Piano option kit).
The following table lists the four disks that come with the SD Piano option, and describes the contents of
each disk.

SD Piano Option Information
Sympathetic Vibrations
Sympathetic Vibrations
When you play a chord on an acoustic piano and hold down the keys while the notes decay, the dampers
on the corresponding strings remain up, and you hear a particular set of harmonics that evolve from the
undamped strings. You don’t hear any significant harmonics from the other strings.
If you play the same chord and hold it with the sustain pedal, you’ll hear a much different, richer set of
harmonics as the notes decay. That’s because all the strings are undamped, and each string gradually
begins to vibrate at its resonant frequency, in response to the vibrations of the strings struck by the
hammers.
This phenomenon is called sympathetic vibration, and is an important component of the sound of an
acoustic piano. The most noticeable of these sympathetic vibrations come from the strings whose
fundamental pitches match the harmonics of the strings that were struck by the hammers.
To create a more realistic acoustic piano sound for the SD Piano option, Kurzweil sound engineers have
developed special effects settings that imitate sympathetic vibrations. When you’re playing one of the
SD Piano programs with ID 700–713, and you’re not using the sustain pedal, the K2600’s audio signal
passes through FXBus 1, then to the AuxBus, which applies a typical room or hall reverb.
When you use the sustain pedal, the signal passes FXBus 1 and FXBus 2 before going to the AuxBus.
FXBus 2 applies a chain of reverbs programmed to resemble an acoustic piano’s sympathetic vibrations.
You can use the Data slider (or any physical controller sending MIDI 6) to adjust the level the
sympathetic vibration effect.
Modifying SD Piano Programs
If you want to change the room ambiance on an SD Piano program without losing the sympathetic
vibration effect, use the Studio Editor to assign a different effect on the AuxBus of the studio used by that
program. If you want to remove the sympathetic vibrations, remove the effect from FXBus 2.
Changes in This Revision
This is Revision B, which includes two changes relative to the previous revision (Revision A).
Page 1 In the table listing the contents of the disks that come with the SD Piano option, the name
of the file containing SD Piano program and setup information is now OBJSD101.K26 ,
reflecting an update to the contents of the file. The previous name of this file was
OBJSD100.K26 .
Page 1 The description of the file OBJSD101.K26 now instructs you to install the file in ROM . In
the previous revision, it instructed you merely to install the file.
