FLOPPY DISK DRIVE
The floppy disk drive (mounted on the left-front of the unit), allows you to transfer
sounds and sequences in and out of the Emax II and allows you to “back-up” your
precious work permanently.
HARD DISK DRIVE
Why hard disks? There are two big advantages to using a hard disk over floppy disks.
■ Greater storage. The hard disk can hold many banks; the floppy, half a bank or less.
■ Faster access time. A 1 Megabyte bank can be saved from the Emax II to the hard disk
in 12 seconds (as opposed to 2 minutes for saving to floppy), or loaded from the hard disk
to the Emax in 6 seconds (as opposed to 50 seconds from a floppy). In most cases, you
can treat the hard disk like a super-floppy; transferring data to and from the Emax II is
straightforward.
SCSI
SCSI (pronounced skuzzy) stands for Small Computer System Interface. SCSI is an
industry standard hardware and software specification that allows high-speed data
transfers between different pieces of equipment. SCSI devices can include hard disks,
tape drives, optical disks and other types of digital equipment. Why use SCSI? SCSI is
FAST! SCSI is a parallel interface which transmits 8-bits of information at a time at high
speed. MIDI in comparison, is a serial interface which can only transmit 1-bit at a time.
■ Each device on the SCSI bus has its own ID number so that it can distinguish its data
from data meant for another device. Each SCSI device must have its own unique ID
number. Most SCSI devices have hardware defined ID numbers. This means that there
is a little switch somewhere on the device to change the ID number.
■ Keep SCSI cable lengths as short as possible. Data errors may occur with long cables.
VELOCITY-SENSITIVE KEYBOARD
A velocity-sensitive keyboard measures how long it takes for a key to go from the key
up to key down position, and uses this data to control dynamics. If it takes a long time
for the key to reach the key down position, it is assumed you are playing that key less
forcefully (minimum dynamics). If the key goes to the key down position almost
instantaneously, it is assumed that you are playing the key more forcefully (maximum
dynamics). In this manual, we will refer to playing the keyboard “harder” or “softer,”
even though technically speaking the keyboard is reacting to speed of key position
change, not force.
PRESSURE-SENSITIVE KEYBOARD
A pressure-sensitive (also called aftertouch) keyboard responds to pressure applied to
a key after it is down. This pressure data is typically used to control vibrato amount,
pitch-bending, and so on after the key is down. Emax II can respond to pressure when
an external keyboard with pressure sensitivity is controlling the Emax II via MIDI.
