Q:
Several Sounds are plays to high (tune up) in Audition.
After loading these sounds they are tuned down. You see that in the Sample list.
The Sounds are from the Original MPC Sound Library.

A:
The audition of a load mode is pronounced by "TUNE" 00:00.
Because, there is no column of "TUNE" in a standard WAV file.
"TUNE" works on the screen of TRIM.
"TUNE" which the sample has is the format of AKAI original.
Therefore, it works only inside MPC.
----------------------------------------------------------------------------------------------
Q:
Is there any possible way to get in more than 998 samples....i need this bad

A:
The file with more MPC than 998 does not read.
Moreover, more files to a load mode than 998 are not displayed.
----------------------------------------------------------------------------------------------
Q:
Several Sounds are plays to high (tune up) in Audition.

All auditions are the sound of a full level.
-----------------------------------------------------------------------------------------------------------
Q:
In 16 Levels, the Decay Mode does not work. (OS2)

A:
Please set the value of "SUS" to "0" on the screen of F2 (AMP) of GPE (MODE+PAD7) mode.
It will not be effective if the value of "SUS" is "100."
-------------------------------------------------------------------------------------------------------------------------------
Q:
I noticed that when i switch back and forth between os1 and os2 some some of the programs settings are totally changed and sound different

A:
That is because there is no ADSR in OS1.
---------------------------------------------------------------------------------------------------
Q:
Do You ever intend to implement multi-timbrality mode on MIDI IN?
Is the functional addition of the MIDI implementation of the internal parameter by "MIDI CC" possible?

A:
The addition of this function was tried.
However, many change was required, and since it became clear that OS had to be remade fundamentally, JJ said that an addition was
difficult.
For making this OS, JJ said that two years of time would be required.
Therefore, though regrettable, the MIDI implementation of the internal parameter by "MIDI CC" is actually difficult.
--------------------------------------------------------------------------------------------------
Q:
For exemple when slider are mapping to Tune in Real Time on all of pads of one track. If i move the slider to an other value
while the mpc is playing and i stop the mpc, it will not keep this value when i play sart again. The position of the slider will not
coincide (match) with the real value.

A:
It has united with the specification of AKAI there.
If it changes, a claim will come from the user who used until now.
Since a problem arises in others, it cannot change.
--------------------------------------------------------------------------------------------------
Q:
i was referring to the bug report below me. it was not an issue of my pads being defective, it has worked fine when
using the akai os, it seems to be a bug when using the 16 levels and tune at 13, it causes some pads to skip and
when moving fast between the 16 pads. when using the akai os i get no problems at all with this issue. ive also
wondered when the update is coming it said septemeber the 8 its now the 12?

A:
If Ver4.85 is the same, please report again.
----------------------------------------------------------------------------------------------------
Q:
1 main mode
2 keep pressing tap tempo + 1/16 (F3)
= Q 1 after + numeric button highlight
3 If pressing tap tempo + 1/16 + numeric = next seq mode
4 if pressing tap tempo + 1/16 + pad bank A = play
5 if pressing tap temo + 1/16 + pad bank B = 16 levels highlights.

A:
This is not a bug.
It is a problem of hardware.
OS of AKAI is also the same.
There is no problem functionally.

1. delete files from CF
2. mode save
3. hit window on "memory card" 4. free memory space does not change = BUG

It does not change, even if it deletes 99KB or less of file.
Probably, the place which does not change even if it deletes 100KB or more of file is a defect of CF card.
