Using The Lfo - Akai S950 Operator's Manual

For example, with a simple string program with gust one keygroup, to thicken
the sound, simply make a copy of that keygroup in Page 03 and then detune it
in Page 06. In a more complicated mufti-sample program that has, for example,
four keygroups, copy KG1 to create a new keygroup, KGS, copy KG2 so the you
create another new keygroup, KG6, copy KG3 so that you create another
keygroup, KG7 and copy KG4 to create KGB. Now detune keygroups 5-8 slightly.
Of course, you are not limited to gust detuning them slightly as you can use
the TRANSPOSE field in Page 06 to split them in octaves or fifths or any
other interval.
This layering technique can be extended even further to layer, for example,
strings on top of brass. To do this, copy a strings program to create another
program such as STR-BRASS .or whatever. Now, using the PUT and GET functions
in Page 03, place the various keygroups from a brass program into STR-BRASS -
the original string sound is now layered with the brass program. Of course,
after that, you may choose to detune them slightly or split them in octaves.
It is also possible to layer three sounds on top of each other for an even
greater range of possibilities but please note: LAYERING KEYGROUPS REDUCES
POLYPHONY. WITH TWO KEYGROUPS LAYERED, THE 5950 WILL ONLY BE ABLE TO 'PLAY A
MAXIMUM OF FOUR
POLYPHONY EVEN MORE, Of course, if the sound you are creating is a solo
sound, this needn't be a problem - it's only when you wish to play chords
that you may notice some notes missing if the number of notes played exceeds
4.
One interesting layering technique uses the WARP facility on Page 12. Try
this.
Using a simple vocal program that has gust one keygroup with an 'aaah' vocal
sample in it, copy the keygroup and detune one of them so that you now have a
richer 'aanah' sound. Now go to Page 12 and on gust one of the keygroups, set
the display to read:
and play a note. You will notice that keygroup 1 slides up to the note whilst
the other remains in tune during the attack. This creates an Interesting
detune effect during the attack portion of the sound. This technique is very
useful on vocal sounds as it is normal for there to be a slight pitch slide
on 'the real thing'. It is also useful on brass sounds which sometimes have a
tendency to slide up into a note. Of course, the settings given above are
only an example so please feel free to experiment. You could, for example set
longer or shorter warp times or have the pitch sliding down - you could even
have one keygroup sliding down and the other sliding up and at different warp
times!! You could also use velocity to control the slide. Again, endless
possibilities.

USING THE LFO

The low frequency oscillator found on Page 14 is a most useful device. Its
prime use is to add vibrato and other pitch sweep effects to a sample in e
keygroup but it can have other uses as well.
