Filter Section

The Filter Type drop-down menu lets you select a filter for the selected

pad. See the Filter definition in the Glossary for an explanation of the

available filter types.

Cutoff controls the cutoff frequency for low-pass and high-pass filter

types or the center frequency for band-pass and band-stop filter types.

Reso controls 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.

Env determines 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.

The Modulation Sources set the amount for different modulation. The following modulation sources are

available:

• V>Start (for Drum Programs only) sets how much velocity is needed (for a triggered pad or key) to

modulate the sample startpoint.

• Kbd>Flt (for Keygroup Programs only) sets how much aftertouch data (from a pad or a MIDI-

keyboard) is needed to modulate the cutoff frequency.

• V>Atk (Velocity x Attack) sets how much velocity is needed (for a triggered pad or key) to modulate

the Attack phase for the Amp envelope.

• V>Env (Velocity x Envelope) enables velocity information to control the amount of the filter

envelope's effect on the cutoff frequency.

• V>Flt (Velocity x Filter) uses the velocity of a pad or key to modulate the cutoff frequency directly.
