Filter Envelope
Use the
Type
field to select a filter for the selected pad. See
Appendix
>
Glossary
>
Filter
for an explanation of the
available filter types.
Use the
Cutoff knob to set the cutoff frequency for low-pass and high-pass filter types or the center frequency for
band-pass and band-stop filter types.
Use the
Reso knob to set the resonance/emphasis of the frequencies around the cutoff point.
Tip : Use values lower than 80 to give more brilliance to the sound. At values higher than 80 , the sound will result in a
strong audible boost around the cutoff frequency.
Use the
Env
to determine the amount of influence the filter envelope has on the cutoff frequency. Higher settings will
increase the modulation of the filter by the envelope; lower settings will result in only subtle changes of the filter
Cutoff over time.
Tip : To give a sound a more distinctive attack , increase the Env setting and set low Atk and Decay values as well
as a medium-low Sust value of the Filter Envelope . This will start a sound with the filter opened and close it shortly
afterward, giving it a bright start followed by a darker sustain. String sounds, on the other hand, can sound much
more “alive” with low
Env settings and a high Atk value, resulting in a slight fade-in of the higher frequencies.
Use the
Modulation Sources knobs to set how much velocity is required to modulate certain other parameters:
Kbd > Flt (Keyboard
x
Filter) sets how much aftertouch data (from a pad) is needed to modulate the cutoff frequency.
Vel
>
Atk
(Velocity x Attack) sets how much velocity is needed (for a triggered pad) to modulate the Attack phase
for the Amp envelope.
Vel > Env (Velocity
x
Envelope) enables velocity information to control the amount of the filter envelope’s effect on
the cutoff frequency.
Vel > Flt (Velocity x Filter) uses the velocity of a pad to modulate the cutoff frequency directly.
