Amiga Computing - Commodore Is Awesome

)0-
recording normal performance data,
Pro-24 has an extra supervisory track
called Master Track.
This cannot store music data, but
instead is used to hold time signature
and tempo information, therefore
allowing both the tempo and time
signature to be changed many times
within a piece.
Amiga sequencers have always been
rather weak where composing
percussion parts is concerned: Even
MusicX failed to address this problem.
But now Pro-24 comes to the rescue
with a unique drum editor that is sure
to win it favour among many
musicians. In truth, the drum editor
isn't really that much different from
the grid editor, so most musicians
have probably been getting along fine

with what they already have.
Songs are built up by pulling
together several sequences using a
reference track. To make this task
somewhat easier, Pro-24 offers an
Arrange window that does just that —
it arranges songs.
Just like the Master Track ,this
reference track does not include actual
music data. Instead, it contains cue
points that specify when Pro-24
should play particular patterns.
For the experienced MIDI musician,
this system will more than adequately
handle the task of song arrangement,
but I couldn't help feeling that many
others could easily be overwhelmed
by what is undoubtedly a rather
unfriendly system.
Steinberg have put a lot of work into

COVER STORY
MUSIC MATTERS
MIDI Musicial Instrument Digital
Interface — the protocol that allows
you to connect your musical keyboard
to your computer. Physically it looks
like a 5 pin DIN plug.
SYSTEM EXCLUSIVE — Also known as
Sysa. SysEx is the "loophole" in the
MIDI protocol that was deliberately
included to allow individual
instrument manufacturers to design
their own extensions to the MIDI
language. This enables instruments of
the same type to talk to each other
through MIDI even when there are
other incompatible instruments
connected to the same MIDI network.
SMPTE (Pronounced "SIM-TEE") —
The full name is actually SMIYrE/EBU
(which stands for "Society of Motion
Picture and Television
Engineers/European Broadcasting
Union"). SMPTE is a system which
allows music to be synchronised to
film.
MIDI TIME CODE — Yet another
synchronising system that is used
specifically to synchronise MIDI
instruments. Pro-24 offers support for
both these synch'ing systems.
OUANTISATION Most music assumes
an underlying regular pulse on which
the timing of each note is based. A
quantiser corrects any timing errors
within a sequence by aligning notes
with this pulse, therefore giving the
sequence a smoother and more
regular feel.
TRANSPOSITION — Transposing a
sequence allows it to be played in a
different key from that of which it was
recorded in. For example, transposing
a sequence by +12 knocks it up an
octave.
MIDI CONTROLLERS — MIDI
Controllers are a bit like SysEx
messages, but instead of only being
able to be understood by instruments
of the same make and model, they
can be understood by all MIDI
instruments. They allow you to
control such properties as the volume
or modulation of an instrument and
the ability to pitch bend notes.
PPON — Stands for Pulses Per
Quarter Note. All sequencers use a
very high resolution clock that times
each MIDI event as and when it
happens. A single PPON is the
smallest possible unit of sequencer
time. In general, the higher the PPON,
the more realistic the recording.
