Panpot
Use this parameter to change the stereo placement
of the selected instrument. “0” means “no change”,
negative (–) values shift the instrument towards the
left and positive (+) values shift it towards the right.
NOTE
In the case of Drum Sets, this setting applies to all drum/
percussion instruments. There is also a parameter that can
be set for specific drum instruments. See page 53.
Octave (T)
Use this parameter to transpose the selected instru-
ment up or down by up to 4 octaves.
Velocity
This parameter allows you to modify the velocity
range of the instrument in question. “0” means that
the recorded velocity values are left untouched, neg-
ative values reduce all velocity values by the same
amount (leaving differences between notes intact),
while positive settings increase all velocity values.
Cut Off
This filter parameter allows you to make the selected
sound darker or brighter. Positive settings mean that
more overtones are allowed to pass, so that the
sound becomes brighter. The further this value is set
in the negative direction, the fewer overtones will be
allowed to pass and the sound will become softer
(darker).
NOTE
For some sounds, positive (+) “Cut Off” settings will cause
no noticeable change because the preprogrammed “Cut
Off” parameter is already set to its maximum value.
Resonance
This is a parameter one invariably associates with a
synthesizer. When the “Resonance” value is increased,
the overtones in the area of the cutoff frequency will
be emphasized, creating a sound with a strong char-
acter.
NOTE
For some sounds, negative (–) “Resonance” settings may
produce no noticeable change because the resonance is
already set to the minimum value.
The following parameters allow you to set the
sound’s “envelope”. The envelope parameters affect
both the volume (TVA) and the filter (TVF). The cutoff
frequency will rise as the envelope rises and fall as
the envelope falls.
Attack (T)
This parameter adjusts the onset of the sound. Nega-
tive values speed up the attack, so that the sound
becomes more aggressive.
Decay (T)
This parameter adjusts the time over which the
sound’s volume and cutoff frequency fall from the
highest point of the attack down to the sustain level.
NOTE
Percussive sounds usually have a sustain level of “0”. Piano
and guitar sounds are in this category. Holding the keys for
a long time will have little effect on the duration of the
notes you are playing, even if you select a high value here.
Release (T)
This parameter adjusts the time over which the sound
will decay after the note is released until it is no
longer heard. The cutoff frequency will also fall
according to this setting.
NOTE
Some sounds already contain natural (sampled) vibrato
whose depth or speed cannot be changed.
Use the following three parameters if you think the
instrument in question has too much (or could use a
little more) vibrato.
