• TRANSPOSE - Some
of
the better arpeggiators will play the pattern, then transpose it
by an amount you specify, then play the pattern again and transpose it and
so
on.
• SOURCE - While much
of
the time you will hold notes to be arpeggiated on the
keyboard, sometimes you will want to play some pattern without actually holding
the keys. Some units will let you hold a set
of
notes to be arpeggiated in their
"memory". You then need to select the "source" for the arpeggiator:
Do
you want
to arpeggiate what you are playing from the keyboard
or
what
is
being held in the
memory?
Cloning
Beyond that, not too much is standard. The picture above shows what this basic structure
looks like. There
is
a clock generator (a metronome
of
sorts) which allows you to control
the rate at which the notes are played. This drives a function which we call
Clone
which
makes copies
of
the notes you play and alters them by parameters such as the mode, order,
and rhythm.
What
does the clone function do? Let's start out with what happens in a
simple arpeggiator. The figure above shows the two main parts
of
simple cloning:
Deciding when to play the next note, and deciding what pitch it should be.
The
clonc
function keeps track
of
when the next note should play and for how long it
should play. For example
if
you wanled to have new notes
be
generated on quarter notes,
the
clone function would
be
waiting for the clock to reach the first beat, then the second
beat, then the third beat and so on, just like a sequencer would. When the clock reaches the
next "Start" time ,clone creates a "gate". That is, clone says
"We
should start playing a
note now and it should
last for an eighth note."
Ordcr
Note that the previous sentence did not say what pitch should be played, it only said that
something should be played and that it should last for a certain length
of
time.
The
order
function looks at the sources that are active (memory, the keyboard,
or
both) and picks
which pilch to play for each gate. Which one
is
picked depends on whether you want play
back the notes from lowest to highest, highest to lowest, random,
or
whatever.
Auto-
Transpose
After the clone function generates new notes, they can
be
transposed automatically by the
Auto-Transpose function. Remember, clone generates a pattern
of
notes based on what
you play and what is in memory. Auto-Transpose changes the pattern into a new key after
each time the pattern is played.
That
is
about all that most arpeggialors do. In the Cyclone there are a lots
of
other things
going on as well. We'll get to most
of
those later in the manuaL There are a few other
relevant things that are important
in
understanding how the CyClone works.
