MPC 5000 OS 2.0 Bug Thread

Hi to all you 5K users,

I stumbled over an issue using patched phrases and have fixed the following steps to reproduce it:

1) Connect a synth to your 5k so that you may record a midi-sequence, play it and record the output of the synth with the 5k.
2) Chose a simple drum sound or synth tom or whatever on the connected synth.
3) Midi-Record a simple 2 bar drum pattern on the 5k with that synth sound and a time correction of 1/8th at a tempo of 120 bpm.
4) Start the sequence and record the output of the synth in record mode. Record the 2 bars with a little extra time before and after for better trimming.
5) Enter trim mode and trim the recorded 2 bar sample so that it loops smoothly and with correct timing.
6) Discard the the sample date outside the loop using the discard function. We now have a 2 bar loop that's running perfectly at 120 bpm. Now we want to convert it to a patched phrase in order to make it loop correctly at different tempos:
7) Still in trim mode you chose the chop function and tune it until we have a nicely chopped sample with one region for every drum hit. You probably get an useless first region, that's not much more than a short click of chopped silence (a bug?). You can merge it with the next region using the region edit functions. (I wanted to simply delete it, but I didn't find an way to do so ... a missing feature?)
8) Convert the chopped sample into a patched phrase using the default settings and a tempo of 120 bpm. You get a new patched phrase sample that probably sounds absolutely fine.
9) Create a new sample program and put the patched phrase sample we recorded on pad A01.
10) Select a new sequence, make sure it's 2 bars long and in loop mode, select the new program on track 1 and record the pad hit that's necessary to trigger the patched phrase and make it loop. Listen ...

FIRST POINT:

If you turn on the click you will hear that the patched phrase is running to fast. At 120 bpm it's running at something like 123 bpm. You may change the tempo and the patched phrase will follow the tempo change but it's always running to fast. Using the original sample we recorded, the timing is perfect. But this won't follow our tempo changes as we all know. I also tried it with bass lines and arpeggios. The patched phrases always run to fast.

SECOND POINT:

Ok, maybe we have done a mistake and the tempo settings of the patched phrase have to be adjusted. As the manual says we enter trim mode, select the patched phrase sample, select the sample field, press the window button and get a window screen that shows tempo and tune parameters of the patched phrase. But we don't! All I get on my MPC is the regular window with settings for tuning and root note. I have never seen that screen, even if it's printed in the manual. (As I have never found the spacey reverb in the effect mode ... )

Can anyone reproduce that behaviour? Did I misunderstand the patched phrases or did I make a mistake? If I'm wrong, great, tell me how to do better. If I'm right, this might be a bug ...

Sorry for the long and detailed description, but that's what Akai is asking for, for the known reasons. Hope it's helpful.

Cheers!

I uploaded a small Movie how my MPC reacts when scrolling through different Programs (with 64 samples each) while a sequence is running (only 30 MB of samples loaded, 192MB installed).
I just sequenced a 4x4 beat so it will be clear that the scrolling
1) locks up the Gui
2) timing/sync is completely lost !

This is behaviour in V2.0, 1.2 is reacting much better...but I want to be able to use V2.0 !!

The video does work for me

The file could not be found. Please check the download link.

wtf?

problem is that the video can only be downloaded 10 times, then rapidshare deletes it
too bad we cannot upload information up here...

Hey Seiko, this problem must really be annoying. Ive been following ur posts about this bug in the thread u made, and i plan on working like that too, loaded programs with fully loaded ram too. (Havent bought 5000 yet) But these problems are whats scaring me from buying the 5000. If i know 100% akai will fix this i will buy one tomorow. But i am abit scared they wont.
Could you try and find another host to post this video up, i really would like to see this.

Also, that REALLY slow loading of samples into Ram you mentioned, if there are many (1000+ samples), sounds annoying too..

U3, Once they do get these bugs fixed in this OS 2.0, i think this would definitely give this machine its cred.... at the moment though, its still not the greatest representation of the Akai MPC line up, but has the opportunity to be one.

I'm new to the MPC5000, so I'd appreciate if someone could check the following issue to see if they get the same results, or else tell me what I'm doing wrong:

I'm using the SOLO function in TRACK MUTE mode.

step1:
Go into TRACK MUTE, hit a few pads to mute the corresponding tracks, and leave some other tracks playing. Fine so far.

step2:
When I hold [F6](SOLO) and hit a pad, let's say pad A4, it goes into solo mode, so only Track-04 is playing and all the other tracks are mute. Just as it should.

step3a:
When I press [F6](SOLO) again, it goes out of solo mode. Just as it should.
Whichever tracks were playing before solo mode are playing now, and whichever tracks were muted before solo mode are muted.

But suppose instead of step 3a, I do this:

step 3b:
Hold [SHIFT] and press [F6](SOLO).
According to the OS 2.0 manual (p.81), I think it should take me out of solo mode, but leave all track mute settings unchanged. In other words, I expect Track-04 is still playing, all the other tracks are still muted, and I'm no longer in solo mode.

But that's not what I get. I get the same results using either step 3a or step 3b.
When I exit solo mode, with or without holding the [SHIFT] button, it always reverts to the same mute status as before I entered solo mode.

If I understand the manual correctly, I should be able to use SOLO function to cut back to the bare-bones beats on one track, then exit the solo mode holding the [SHIFT] key so nothing else changes, and then use the regular TRACK MUTE method of bring other tracks back one-by-one into the mix.

Anyone else get the same problem? Or am I misunderstanding the way it should work??

THIS O S IS JUNK. AKAI IS GETTING FLAMED FOR THIS IF ITS THE LAST THING I DO.



:angry

Editing a sample in TRIM MODE during an active sequence in which said sample is used produces a whining sound. (OS v.2)

Let's say we have a sample file assigned to PAD1 called "snare33". You make a loop that uses "snare33" (amongst other samples) and now while the loop is playing you enter TRIM MODE and rollback the "snare33" end point to make the sample shorter. What happens is the next time "snare33" note turns on in the loop (which is already playing/ in play) it will emit a whine instead of the newly edited version that won't go away even if you stop the loop. You have to restart the MP to get it to go away.

I tried the feature and yes it don't work. But, if you leave the the first track or what ever track you have solo in solo mode. Then press shift and select another track at the same time. You can stay in solo mode and bring other tracks back one-by-one into the mix.

was around at a friends house last night messing round with mpc5000 for a while....couldnt beleive it that you cannot purge unused samples....also some of the samples could not even be edited..wtf is that....man i am so happy i never got meself an mpc5000....is there any news from whAKAI about when a new O.S. is coming or should i tell my friend to sell it before word gets round about this crap o.s.

yes you can.

Not sure if this has been posted already but if you save something, a program or all sequences and songs more than once without altering them the machine comes up with an error that says "device not found ??" it's happened to me a couple times.
