Akai MPC 4000 Reference Manual page 160

• 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.
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.
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.

Function
Adjusts the delay time of delay 1.
Adjusts the delay time of delay 2.
Adjusts the delay time of delay 3.
Adjusts the amount of delay feedback.
Adjusts the frequency at which the high-frequency region of the
feedback sound will be cut.
Adjusts the panning of the effect sound.
Adjusts the balance of the effect sound and dry sound. (With a
setting of 100/0, only the effect sound is output.)
Switches the effect on/off.
Function
Adjusts the modulation speed (LFO) of the wah effect.
Adjusts the depth of the effect.
Adjusts the amount of resonance.
Enables (ON) or disables (BYPASS) the effect.
Specifies whether the effect will be enabled (ON) or bypassed
(BYPASS).
Function
Adjusts the level (threshold) at which the wah effect is applied.
Adjusts the depth of the effect.
Adjusts the amount of resonance.
Enables (ON) or disables (BYPASS) the effect.
Specifies whether the effect will be enabled (ON) or bypassed
(BYPASS).
