Forum to discuss all matters relating to the MPC1000 and MPC2500 operating systems created by 'JJ' (all versions).

Hi guys,

Couple strange, glitchy things happening. Which I've only noticed now, because in 5 years I have never really used the Q-link sliders! P.S. I bought the MPC2500 second hand, with "JJ-OS XL version 1.23" already on it.

My questions:

1) When I turn one of the Q-link knobs (Q4), it alters it's own 'value', as well as the value for one of the sliders (Q1)

2) When I slide Q-link slider (Q1), sometimes it's value changes (between 80-127); other times it doesn't react at all.

3) My hunch is that this is a non-mechanical issue, and has to do with some kind of bug? I sprayed some electric cleaner in the Q1 slider but that hasn't helped.

4) I thought I'd look on the net for someone who has the same OS as me. But as far as I can tell, I'm about the only person in the world with this particular version of JJOS (JJOS-XL version 1.23 is what is says on load up). Or does this particular version go by some other name? For instance, on the JJ-OS comparison page, I can't see "JJOS-XL version 1.23" listed anywhere. But I do see OS-XL there. Is JJOS-XL version 1.23 the same as OS-XL?

5) Does this look like a bug issue to you guys? And suggestions for a solution? I see that at least one other person has noticed "crosstalk" between Q-link controls... viewtopic.php?f=21&t=141325.

Do I need to update my JJ-OS perhaps? Ideally I would like to use the Q-links to control aspects of Ableton live.

Any help is much appreciated!

Dude, you need to upgrade your JJ OS .. You're running 1.23 but 3.49 is the current revision now. :/

Cables, joints :smoker: inside and slider malfunction itself (dirt, sand or some crystals , high humidity (spilled milk), fried... etc.

make sure you are make good moves by reading Akai manual about sliders, and than jjos manual about sliders for your OS

(every OS has way it diffrent)
