Filter Section - Akai MPC Essentials User Manual

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
the Attack phase for the Amp envelope.
• V>Env (Velocity
envelope's effect on the cutoff frequency.
• V>Flt (Velocity
Attack) sets how much velocity is needed (for a triggered pad or key) to modulate
Envelope) enables velocity information to control the amount of the filter
Filter) uses the velocity of a pad or key to modulate the cutoff frequency directly.
