JJ OS Bug Reports (ARCHIVE)

BUGS REPORTED LAST WEEK

MPC1000 0S2 Ver 1.27 (also occurs on 1.26)
1. SONG MODE: Record sequences containing an AUDIO TRACK. After recording SONG TO SAMPLE, AUDIO TRACK changes the original sample that was recorded to that track with another sample that's loaded in memory.

2. AUDIO TRACK bug on MPC1000 OS2 ver 1.27 AND OS2XL ver 1.24
When AUDIO TRACK is not selected on main screen to the corresponding track number, the recorded audio in that track will truncate after the first bar. However, this only happens at the beginning and does not repeat when the loop returns to the first bar. This is still very annoying when recording in song mode and recording SONG TO SAMPLE.
I found a workaround.... No matter how many audio tracks I have recorded, if the first AUDIO TRACK on the main screen the main screen is selected for all sequences, all of the audio tracks will play out properly without truncating.

If anyone can verify these bugs, respond here and report it to JJ as well. So far, I havent heard anything from them, and I'm not looking to try and find the earlier OS versions where the problems never occurred. It's not worth it to downgrade and deal with previous bugs that also may prevent my workflow.

MPC2500 JJ OS-XL:

[1]



note can be writen in - before fat line and thin line.

Bug - Users shouldn't be forced out of a MODE until the Main Key or MODE + PAD is pressed.

While in SEQ EDIT MODE, if your press F6 (Do It) after changing various perimeters, you are returned to the Main Screen. This is annoying because you have to re-enter SEQ EDIT MODE numerous times if you need to make additional edits. However, if you are in STEP EDIT MODE and you INSERT EVENT, you remain in STEP EDIT MODE even after you Press F5 (Do It). SEQ EDIT MODE should behave the same way.

I believe this has been an issue with ALL Akai and JJ OS for the MPC 2500/1000 for years but never addressed until the MPC 5000 OS2.

OS2XL 1.25

LOOP EDIT BUG:

Loop edit does not work properly on banks B,C,D
1. select bank B
2.hit pads - no notes are inputted on bank B
3.select bank a - notes have been inputted to bank A

note:
1.select bank b, move cursor to choose pad e.g.(bank B, pad 5)
2.press bank a
3.hit pads - no notes are inputted
4.select bank b : notes have been inputted on the original chosen pad.e.g.(bank B pad 5)

OS2XL 1.25 for 2500

Loop Edit: I can hit the pads to place drum hits (x0x-style), but only bar 1 allows them to be deleted by hitting the pad a second time. Bars 2+ can add the hits, but not delete them.

1000 2XL 1.27:
Crash:

Did nothing special, loaded 2 samples, chopped one, the other set to xfade loop (but didnt play when the crash occured). Crashed while playing the pads...

Strange Loop screen in Loop Edit:

Power on
Mode GRID EDIT
LOOP EDIT on
Play Start
Push BAR >> to bar 2
Push BAR >> to bar 3
Push BAR >> to bar 4
Loop screen is strange.



Anyone confirm?

Peace!

OS-XL 1.29: Sample direction bug

1. Program mode
2. Goto "DIR." where it says "FORWD"
3. Press "+" button on MPC 10 times and it says "REVRS"
4. To make it say "FORWD" again you must press "-" 10 times

Already reported.

confirmed but maybe it's not real time and we have to wait till the sample is entirely played.

[MODE]+[MIXER]+[PAN] DOES NOT WORK CORRECTLY. SOUND ALWAYS PAN TO LEFT OR RIGHT WHEN CENTERED.

JJ OS2XL 1.30.

Horrible distortion when using EQ as "Input Thru Pitch Shift" Insert FX. This happens even when you set the FX level to O.

EDIT- I determined it was a feedback look between my MPC and Fantom since they are connected to each other digitally via both inputs and outputs. But the problem only occurs using the MPCs EQ as an FX.

XL 1.33
16 LEVELS - VELOCITY - not work

Yes it does.
Read: http://www7a.biglobe.ne.jp/~mpc1000/mpc2500/bug/ near the top.
16 LEVELS - VELOCITY relies on what your VELO setting is in PROGRAM.
It works fine for me on JJOS2XL 1.33.
