ABOUT EFFECTS
Ensemble - an overview.
This effect is designed to simulate the “Ensemble” effects found in classic “String Ensemble” keyboards like the Solina or the
Roland SE101. This is similar to Chorus in the sense that Ensemble provides an effect that fattens up sounds & provides a stereo
image but without the swirling sensation. It could in actual fact be thought of as 4 independent Choruses all running at different
speeds, thus masking the “wobbly” sensation that Chorus can produce. This is particularly suitable for string sounds as it sounds
smoother than Chorus for this purpose.
Chorus - an overview.
This is an effect originally designed to simulate the effect when many people sing together as opposed to one person or the sound
of a 12 string guitar as opposed to a 6 string guitar. Chorus is an effect that is produced by detuning the signal slightly & mixing it
back together with the original signal. The characteristic Chorus swirling effect is produced by an LFO that controls the amount of
detuning the chorus performs.
Quad Chorus.
This is a effectively 4 Choruses running at once from one LFO but in different phases. This creates a particularly “thick” Chorus
effect suitable for String Ensemble & other “Lush” sounds.
Chorus/Flanger.
.
Normal Chorus & Flanger effects are quite similar. Using this effect as a Chorus provides a Stereo effect with a smooth swirling
sensation that fattens up sounds & provides a stereo image. This type of Chorus differs from the Quad Chorus in the sense that
although not as “thick” sounding, this Chorus retains the “definition” of the effected sound making it more suitable for basses,
organs & percussive sounds. The Flanger effect is similar to a chorus but tends to use more detuning & feedback to produce an
effect with a pronounced swirling sensation that emphasises the harmonics in the sound as it sweeps through them.
Phaser.
This effect is almost the reverse of a Flanger. A small amount of phase shift is applied to the signal via an LFO. When this is added
back together with the original signal, a pronounced swirling effect is produced that cancels out harmonics in a sound as it sweeps
through them.
Chorus Speed. This parameter controls how fast the LFO for this effect is going. Generally a fairly slow speed is used. Higher
speeds tend to induce a vibrato like quality to the sound.
Mod Depth controls the amount of detuning or phase shift that the effects LFO produces. Again large amounts of modulation from
this parameter will produce a more noticeable effect. Generally moderate amounts are used but you will find that bass sounds ben-
efit with more Mod Depth than normal. Feedback controls how much of the treated signal is fed back into the input. Subtle effects
like chorus benefit from low levels of feedback. Flangers & Phasers on the other hand sound better with more feedback. Feedback
emphasises the harmonics in a Flanger & emphasises the cancellation of harmonics in a Phaser.
The Type parameter determines if this effect is going to be a Chorus or a Flanger or a Phaser. Select the one you want.
The effects LFO should not be confused with the front panel Program LFOs.
Delay.
This effect is normally a single acoustic reflection of a sound. This is commonly called Echo. This effect can be heard naturally any-
where where there is a large flat surface, like a concrete wall. A “Stereo” version can be considered to be two concrete walls & this
is the type that the Supernova II Rack uses. The distance from the walls determines the delay time & in the example below the dis-
tance between the left wall & left ear of the listener is different to the distance between the right wall & the right ear of the listener.
This creates a Stereo “staggering” effect of the echoes & is normally referred to as “Multi Tap Delay” or “Tap Delay”.
