Akai S950 Operator's Manual page 48

DEPTH: This sets the amount of LFO sweep. 0 = no effect with modulation depth
increasing with higher numeric values. With any value higher than 1, the LFO
effect will be n permanent part of the sound.
RATE: This sets the speed of the LFO pitch sweep. 0 = very slow and the LFO
rate gets faster as you increase the settings (note: the ranges of 30-45 are
recommended for typical vibrato effects).
DELAY: ,This sets the time it takes for the LFO to fade in with its effect.
This is particularly useful for natural vibrato effects if yuu are not able
to use the modulation wheel.
DESYNC: There are no less than 8 LFO's in the S950, one for each voice. When
DESYNC Is ON, these LFO's run slightly out of phase with each other allowing
you to create more natural ensemble vibrato effects. With DESYNC OFF, the
LFO's are phase locked and so produce LFO effects more like those found on
synthesizers that normally only have one LFO to affect all voices.
DESYNC is switched on or off using the ON and OFF buttons.
The next page, Page 14, is also to do with the LFO and looks like this:
where # is the current keygroup selection.
This page allows you to add vibrato and other LFO effects over and above
those set in the DEPTH field on Page 13 using aftertouch (if your keyboard
generates it, of course) and/or the modulation wheel. The display shown is
the default and so will not require much, if any editing. As you would
assume, higher values on either of these parameters increases the amount of
effect either aftertouch or the mod wheel will have on the introduction of
LFO effects.
The next page allows you to control tone over the keyboard range as well as
turn the keyboard off and looks like this:
where, once again, # !s the current keygroup selection.
KEY-FILTER is similar to the 'keyboard track' control available on every
analogue synthesizer and this allows you to vary the tonal balance across the
keyboard. This can be useful when using certain samples that 'screech' in the
upper reaches of their range or samples that are noisy when played a few
octaves down. By setting a higher key-filter setting, the sound will get
mellower further up the keyboard. A setting of 00 has no effect on the sound.
The default is 50 and can usually be left.
The CONST PITCH field allows you to effectively turn the keyboard off so that
it will have no effect on the pitch of the sample. This can be useful in a
number of ways. Far example, with a drum program, it is often desirable to
place certain drums over a small range of notes in order to play rolls and
fill more easily. Unfortunately, if you do this, the pitch of the drum
changes so by switching CONST PITCH to ON, the pitch of these drums will
remain constant regardless of what note you play.
