Sound Parameters – Filter
time. Sounds with a hard attack usually have a positive envelope amount that makes the start phase
bright and then closes the filter to get a darker sustain phase. On the other side string sounds usually
use a negative envelope amount that gives a slow and dark attack before the cutoff rises in the sustain
phase.
Velo
Determines the amount of influence the filter envelope has on the cutoff frequency, based on key
velocity. This parameter works similarly to the Env parameter with the difference that its strength is
velocity based. Use this feature to give a more expressive character to the sound. When you hit the
keys smoothly, only few modulation is applied. When you hit them harder, the modulation amount
also gets stronger. The following picture illustrates the functionality of this parameter:
Envelope Depth

Key Velocity = 1...127

Env Parameter = +32
Velocity Parameter = 0
The overall modulation applied to the filter's cutoff frequency is calculated as the sum of both
parameters Env and Velo. Therefore you should always bear in mind what the result is,
especially when the filter does not behave as you expect. You can also create interesting effects
by setting one parameter to a positive amount and the other to a negative.
Pan
Determines the position in the stereo panorama. When the setting is left 64, the sound is panned far
left, when the setting is right 63, it is panned far right. If you want to set the sound into the middle of
the stereo panorama, use the center setting. To give further movement to the sound, set this parameter
to a basic value and apply some modulation to it via the PanMod parameter.
Drive
Determines the amount of saturation that is added to the signal. If set to 0, no saturation will be added
or, in other words, the signal will remain clean. Lower values will add some harmonics to the signal,
resulting in a warm character. Increasing the value will bring in more and more distortion, suitable for
harder lead sounds and effects.
