Akai MPC 4000 User Manual

Effect mode
150
REVERB>THEATER
Stereo reverb that simulates the reverberation of a theater.
REVERB>VOCAL PLATE
Simulates the reverberation of a plate reverb device suitable for vocals.
REVERB>WAREHOUSE
Simulates the reverberation of a warehouse.
REVERB>NON LINEAR
This is a special type of stereo reverb that abruptly cuts the reverb after a certain length
of time has elapsed. The parameters of this reverb differ from those of other reverbs.
REVERB>REVERSE
This is a special type of stereo reverb that plays the reverberation backward. The param-
eters of this reverb differ from those of other reverbs.
ROTARY SPEAKER
This is a stereo-output effect that simulates the rotary speaker often used with organs. You
can use the [F4] key (MANUAL) or control change messages received from the MPC4000’s
MIDI IN connector to switch between the two speeds of rotation (Rate1/Rate2).
• When using the [F4] (MANUAL) key to switch speeds
Each time you press the [F4] (MANUAL) key, Rate1 and Rate2 will alternate. The
Accel field specifies the time over which the speed change occurs.
Parameter Range Function
Pre - delay 1ms –100ms Adjusts the delay time of the early reflections.
Hold 0 –127 Adjusts the time until the reverb is cut off.
Diffuse 0 –127 Adjusts the density of the reverberation.
Width 0 –127 Adjusts the stereo spread.
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
Pre - delay 1ms –100ms Adjusts the delay time of the early reflections.
Time 0 –127 Adjusts the reverberation time.
Diffuse 0 –127 Adjusts the density of the reverberation.
Width 0 –127 Adjust the stereo spread.
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
Rate1 0.1Hz–10.0Hz Adjusts the speaker rotation speed (Rate1).
Rate2 0.1Hz–10.0Hz Adjusts the speaker rotation speed (Rate2).
Accel 0.1sec–10sec Adjusts the time required to switch from Rate1 to Rate2.
Init R1/R2
Specifies the rotation speed (Rate1 or Rate2) that will be used
initially.
MIDIch 1–16
Specifies the MIDI channel on which control changes will be
received.
CtrlNo. 0–127 Specifies the control change number that will be received.
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.
