MIDI
An acronym for Musical Instrument Digital
Interface. MIDI allows electronic musical
instruments to communicate with each other.
Modem
A device which connects and allows data transfer
between a conventional telephone line and a
computer. It converts the digital signals from the
computer to analog audio for sending over the
phone line, and vice versa.
Piano Parts
Refer to the left- and right-hand piano parts of a
song. The left-hand piano part is recorded onto
track 1 and the right-hand piano part is recorded

Provider
A communications business that offers Internet
connection services. In order to connect to the
Internet, it is necessary to contract to a provider.
Proxy
A proxy server is a server that all computers on a
local network have to go through before accessing
information on the Internet. It intercepts all or
designated requests to the real server to see if it
can fulfill the requests itself. If not, it forwards the
request to the real server. Proxy servers are used
to improve performance and speed, and to filter
requests, usually for security and to prevent
unauthorized access to an internal network.
Router
A device for connecting multiple computer
networks. For example, a router is necessary when
connecting several computers in a house or office,
to allow all of them access the Internet and share
data. A router is usually connected between a
modem and a computer, although some modems
have a built-in router.
Sequencer
A sequencer can be used with the Disklavier to play
back and record MIDI data.
Server
A hardware system or computer used as a central
point for a network, providing access to files and
services.

SMF Song Format

Song
Normally, a short piece of music with lyrics.
However, for clarity in Disklavier manuals, the term
is used to refer to any piece of music of any genre.

number of different MIDI devices and computers.
Subnet Mask
A setting used to divide a large-scale network into
