• When using control changes to switch speeds
Rate1 will be selected when a control change with a value of 0–63 is received, and
Rate2 will be selected when a value of 64–127 is received. The CtrlNo. field specifies
the control number, and the Accel field specifies the time over which the speed change
occurs.
TAPE ECHO
This delay effect simulates a three-head tape echo device. Three delays can be set inde-
pendently. The effect itself is mono-in/stereo-out, but you can adjust the panning of the
effect sound if you are playing in stereo.
WAH>AUTOWAH
This monaural effect produces a cyclically-modulating wah effect.
WAH>TOUCH WAH
This is a monaural effect that applies a wah effect when the signal level exceeds a spec-
ified threshold.
Note: To avoid confusion, we recommend that the MIDI channel used to control this effect be different
than the receive MIDI channels used for each of the MPC4000’s parts.
Parameter Range Function
Head 1 1ms–1500ms Adjusts the delay time of delay 1.
Head 2 1ms–1500ms Adjusts the delay time of delay 2.
Head 3 1ms–1500ms Adjusts the delay time of delay 3.
Feedback 0–127 Adjusts the amount of delay feedback.
HFdamp 20Hz–20kHz
Adjusts the frequency at which the high-frequency region of the
feedback sound will be cut.
Pan L63–MID–R63 Adjusts the panning of the effect sound.
Wet/Dry 100/0–0/100
Adjusts the balance of the effect sound and dry sound. (With a
setting of 100/0, only the effect sound is output.)
Effect ON/OFF Switches the effect on/off.
Parameter Range Function
Rate 0.1Hz–10.0Hz Adjusts the modulation speed (LFO) of the wah effect.
Depth 0–127 Adjusts the depth of the effect.
Resonance 0–127 Adjusts the amount of resonance.
Rate 0.1Hz–10.0Hz Enables (ON) or disables (BYPASS) the effect.
Effect ON/BYPASS
Specifies whether the effect will be enabled (ON) or bypassed
(BYPASS).
Parameter Range Function
Threshold –60dB–0dB Adjusts the level (threshold) at which the wah effect is applied.
Depth 0–127 Adjusts the depth of the effect.
Reso-
nance
0–127 Adjusts the amount of resonance.
Threshold –60dB–0dB Enables (ON) or disables (BYPASS) the effect.
Effect ON/BYPASS
Specifies whether the effect will be enabled (ON) or bypassed
(BYPASS).
