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:

Vel>Sta (VelocityStart) sets how much velocity is needed (for a triggered pad) to modulate the sample startpoint.

Vel>Atk (VelocityAttack) sets how much velocity is needed (for a triggered pad) to modulate the Attack phase

for the Amp envelope.

Vel>Env (VelocityEnvelope) enables velocity information to control the amount of the filter envelope’s effect on

the cutoff frequency.

Vel>Flt (VelocityFilter) uses the velocity of a pad to modulate the cutoff frequency directly.

The Filter Envelope controls affect the filter frequency. Use the fields or tap and drag the “handles” of the envelope

to shape the envelope or time-variant modulation output. Adjust the envelope’s influence on the filter frequency with

the Env knob. See the later Anatomy of an Envelope section to learn about the envelope parameters.

The Amp Envelope controls affect level changes over time. Use the fields or tap and drag the “handles” of the

envelope to shape the envelope or time-variant modulation output. Adjust the envelope’s influence on the filter

frequency with the Env knob. See the later Anatomy of an Envelope section to learn about the envelope parameters.
