short sound reflections but lots of them to make
the sound smooth.
The CHORUS processor features time delays from
flanging, to chorusing/phasing and on out to
multiple repeats and echoes. We are talking much
larger than the distance
reflections because these
separate events. The CHORUS processor is more
than just chorus and delay effect types. You even
get additional Reverb algorithms for maximum
flexibility when mixing. There are also tempo
control delays that can be synchronized to the
BPM of the music.
There are six different main categories in the
CHORUS processor:
Reverbs (3 types) – 12 presets
Delays (7 types) – 41 presets
Chorus (5 types) – 28 presets
Flanger (3 Types) – 13 presets
Phaser (3 types) – 37 presets
Miscellaneous (1) – 5 presets
A Flanger is a time delay effect. If two identical
signals arrive at your ear-brain, you will not be
able to perceive them as two separate signals
until one is delayed slightly. Imagine 2 turntables
in perfect synchronization playing the same record
at exactly the same speed. You would perceive
the second one as just making the first signal
louder, until you delayed one of them a bit. If
one slips 1ms behind the other you will perceive
what we call flanging. The actual name comes
from two 2-track reel-to-reel tape decks playing
the same material. This was used as a real time
effect, "back in the day". You would have 2
identical 2-track decks running in sync (no, there
were no protocols to sync them – you pressed the
buttons at the same time!!!) The engineer would
slow one down by placing his thumb momentarily
on the flange (reel holder). The resulting swirling
sound is called flanging. And there were no
settings, no presets – it was all done by ear. It
was a short time later that a Flanger became a
rack mount device – and while the original Flanger
cost around $1500, it was still a lot cheaper than
two 2-track tape recorders!
Any delay between exact sync and 4ms is
considered flanging. Delays of 4ms-20ms are
considered chorusing and somewhere beyond
30ms the ear-brain
separate events, called doubling or echo. Among
the 'time-delay' algorithms

as Phasing is another category of effect – it is where
the two signals are basically the same but instead
of one being a wave that starts in the upward
direction, the second wave starts perhaps in a
different direction.
Each of these main algorithms has their own
"Presets". A Preset simply is a starting point.
Remember, only you can know what is working for
your particular composition. The Presets are
provided and they are meant to be tweaked by
you. They are "starting points". Saying you don't
like any of the presets is, well, if you find yourself
saying this, go stand in the corner and give
yourself a demerit (lol). You are saying that
somehow the original programmer did not know
what YOU like. You are correct, so DO something
about it, learn to tweak the effects!
The INSERTION EFFECT is made up of two
identical units (INSERTION A and INSERTION B).
The 53 effect types and scores of presets can be
the subjects of intense study. We will try and
introduce you to some of the more unusual and
unique ones in this article. Many of the recipes
(algorithms) are repeated in the Insertion Effects
simply to allow you more options when processing
your mixes. In addition to all the reverbs, delays,
echoes, cross delays, tempo delays, etc., you get
some that are available nowhere else. Insertion
Effects can be considered a part of the Voice
itself, and can be assigned real time controllers so
that you can manipulate them while performing.
The VCM (Virtual Circuit Modeling) Effects are
revolutionary
constructed by modeling the circuit components
(capacitors, resistors) of the classic gear they
emulate. The designer then could reconstruct the
products by creating virtual circuit boards. The
VCM Flanger is a simulation of the classic vintage
flanger devices.

Among the innovative effects from the Yamaha
Samplers A4000/5000 are the Lo-Fi, Noisy, Digital
Turntable, Auto Synth, Tech Modulation, Isolator,
Slice, Talking Modulator, Ring Modulator, Dynamic
