2nd mp1000 stutters as hell + sequencing off timing

I bought a 2nd hand mpc1000 and it works like shit, the pads stutter as hell, and also when i record patterns, the sequencer just throws the timing off beat. I have jjos1 installed. Factory reset didnt help either
I tap the kick right on the click of the metronome and when i play it back its off timing.

What can i do about this? Should i go back to the seller or try some reset things??

is the timing always off by the same amount? check the "Timing Correct" (TC) screen, there's a Shift Timing setting which offsets the notes from when you play them

I don't know about the stuttering pads, they might be knackered - is it a red & blue model with the old pads?

Weird it turned out to be Jj OS1, i reainstalled the akai official os and everything was ok.
Is this a familiar problem with jjos?

no.

and you never mentioned if you checked the TC settings... i think it's all in your mind.

he didn't say if it's red & blue either.

Mohammed, if you're going to ask for help, at least read the replies and supply the info needed for someone to help you!

gotta love how newbies try to blame everything on JJOS...

i don t think so...

i had a red/blue mpc what didn t work with jj os!! ( weak cpu?)

now i have a bk one and everything is fine...

it happens because the jj os pushes the cpu harder than akai os....

TC was ON (16th note) and the problem WAS JJOS.
Maybe a new ram expansion will help, try it next week.

but what about the Shift Timing field?

see those words I wrote up there, "Shift" and "Timing"? I didn't do it just to exercise my fingers.

is the timing off for all notes by the same amount, or some more than others? maybe you've got a swing setting on. try holding down ERASE when you install JJOS to make sure you clear out any settings that might be the problem, because it could be a feature of JJOS that you don't know about, rather than a bug

I had problems after install JJOS1 as well. My data wheel only worked after 3 spins and my left cursor was slow. My beats stuttered like crazy. I put back the Akai OS and now all is normal.

I hope my new RAM comes in tomorrow.
