JJ OS128XL & OS3 Manual

This manual is written only about the function added by JJOS.
Please refer to the manual of AKAI for the basic function of MPC.

When you change OS, please switch on a power supply, pressing the ERASE button first.
Please press the ERASE button until a main screen is displayed.
If this operation is not performed, MPC may freeze or it may crash.

When the reaction of a DATA wheel is slow or cannot change the value of one step, please change the set of the "Wheel " field of OTHER.
Usually, MPC in which Ver.2.12 or less AKAI OS was installed selects "Old type".
MPC in which Ver.2.13 was installed selects "New type".
If OS is changed, this set will return to default setting"New type".

Refer to video of user offer.

Notes
The contrast of LCD should turn a DATA wheel, pressing the [STOP] button.

If a DATA wheel is turned pressing [SHIFT] or the [TAP TEMPO] button, change of a value will increase 10 times.

When [FULL LEVEL] button is ON (the LED is lit), the velocity of MIDI IN NOTE is also set to FULL LEVEL.

The sample of MPC cannot be sounded with NOTE from the outside when a note repeat is ON.
Therefore, the note repeat by NOTE from the outside does not work, either.

Q-link does not work to NOTE from the outside.

Since the specifications of OS differ, the sequence created by other OS's may not be played back normally.
For example, the data of Q-link and 16LEVELS is not reflected.
The value of the parameter which is not in the program of 128XL(OS3) is disregarded.

An audio track is skipped when a track is changed during the recording of a sequence.
The type of a track cannot be changed during playback or recording. (Also in a grid, it is the same)
