GM System Level 1
“GM System Level 1” is an addition to the MIDI standard which ensures that any GM-compatible music
data can be accurately played by any GM-compatible tone generator, regardless of manufacturer. The GM
mark is affixed to all software and hardware products that support GM System Level.
XGlite
As its name implies, “XGlite” is a simplified version of Yamaha’s high-quality XG tone generation format.
Naturally, you can play back any XG song data using an XGlite tone generator. However, keep in mind that
some songs may play back differently compared to the original data, due to the reduced set of control
parameters and effects.
USB
USB is an abbreviation for Universal Serial Bus. It is a serial interface for connecting a computer with
peripheral Devices. It allows “hot swapping” (connecting peripheral devices while the power to the computer
is on).
Stereo Sampled Piano
The instrument has a special Portable Grand Piano Voice—created by state-of-the-art stereo sampling technology
and using Yamaha’s sophisticated AWM (Advanced Wave memory) tone generation system.
Touch Response
The exceptionally natural Touch Response feature, with a convenient front panel on/off switch, gives you
maximum expressive level control over the voices. It also works in conjunction with the Dynamic Filter,
which dynamically adjusts the timbre or tone of a voice according to your playing strength—just a like a
real musical instrument!
STYLE FILE
The Style File Format is Yamaha’s original style file format which uses a unique conversion system to provide
high-quality automatic accompaniment based on a wide range of chord types.
