Keywords for MDF3 operation
The terms defined below are used throughout the manual to describe functions pe-
culiar to the MDF3. The same words are frequently used in describing other MIDI
devices, as well; but keep in mind that in many cases the actual function in question
may differ considerably from that performed by the MDF3.
file A position on a disk where data is stored and
assigned a name. The MDF3 is capable of man-
aging up to 99 files on a single disk. The num-
ber of files that can be created on any given
disk is physically limited by the size of the files
and the disk's capacity of approximately 1,200
(MF2HD)/600 (MF2DD) kilobytes.
MDR mode The mode of operation in which the MDF3 is
used to receive and transmit MIDI bulk data.
MDR data The contents of the data file that is created
when the MDF3 receives bulk data from an-
other MIDI device.
reception Generally, the receiving by one MIDI device
of MIDI data from another. In this manual, "re-
ception" refers specifically to the MDF3's re-
ception of bulk data. The MDF3 automatically
writes the bulk data it receives to disk as an
MDR data file.
transmission Generally speaking, the sending of data from
one MIDI device to another. In this manual,
"transmission" means specifically the transmis-
sion of MDR data by the MDF3. When the
MDF3 transmits the contents of an MDR data
file, it simultaneously reads data from the disk
and outputs it via the MIDI OUT jack.
SEQ mode The mode of operation in which the MDF3 is
used to record and play back sequence data.
SEQ data The contents of the file that is created when
the MDF3 records sequence data. Such data is
often referred to as "song data". Strictly speak-
ing, however, such a file can contain as many
as several songs, or as little as a single phrase.
recording The reception of MIDI sequence data. Record-
ing is different from the reception of bulk data
in that the data is received in realtime. The
MDF3 automatically writes the sequence data
it receives to disk as a SEQ data file.
playback The transmission of sequence data from one
MIDI device to another. Playback differs from
the transmission of bulk data in that the se-
quence data is transmitted in realtime. When
the MDF3 plays back a SEQ data file, it simul-
taneously reads data from the disk and outputs
it via the MIDI OUT jack.
