FILTER & ENVELOPES SECTION
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. To give a sound a more distinctive attack, you may
try to increase the envelope amount value and set low ATK and DECAY values as well as a
medium-to-low SUST value of the Filter Envelope. This setting 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 of the Filter Envelope, 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 the amount of a pad or key velocity to modulate
the sample startpoint. KBD>FLT (for Keygroup Programs only) sets the amount of
aftertouch data from a pad or a MIDI-keyboard to modulate the cutoff frequency.
• V>ATK (Velocity>Attack) sets the amount of pad or key velocity to modulate the Attack
phase for the Amp envelope.
• V>ENV (Velocity>Envelope) enables velocity information to control the the amount of the
filter envelope's effect on the cutoff frequency.
• V>FLT (Velocity>Filter) finally uses the velocity of a pad or key to modulate the cutoff
frequency directly.
FILTER ENVELOPE Section
This Envelope is used to control the filter frequency. The four knobs control the Envelope shape
or time-variant modulation output. The influence of the Envelope on the filter frequency can be
adjusted with the ENV parameter.
AMP ENVELOPE Section
This Envelope is used to control level change over time. The four knobs control the Envelope
shape or time-variant modulation of a sound's level.
Select the pad you wish to filter by hitting it on your MPC hardware or
by selecting it in Main Mode of the MPC software.
To edit the FILTER, FILTER ENVELOPE & AMP ENVELOPE
parameters press the F4 button (Flt Env) on your MPC hardware.
Use the MPC hardware Q-Link knobs for direct access of all 16
parameters.
The Filter Type pop-up menu lets you choose a filter type. A
complete list of all filter types can be found in the Appendix of this
manual.
CUTOFF controls the cutoff frequency for the chosen filter types, the
center frequency for the band-pass and band-stop filter types.
RESO controls the resonance/emphasis of the frequencies around
the cutoff point. Use lower values in the range of 0-80 to give more
brilliance to the sound. At higher values than 80, the sound will result
