Hello. I'm really not expecting to solve this but since I know there are a few Akaiexperts here I'm curious if this strange phenomenon can be explained:
I have a few of the old Hollowsun S5000 programs; Stringmachines.
Using an app called Blue Box I could sucessfully convert some of them to MPC1000 program format. However, there are huge problems with the loop points. Almost none of them sounds good on the MPC. I'm sure they didn't sound like that on the S5000 (I don't have it around anymore to test) and I also have those libraries converted to EXS24 where they sound perfect.
A few details I find very strange:
- Fine tuning loop points doesn't help. Not much anyway.
- Loop may sound great on C3 but C#3 sounds awful. Then D2 might sound better and so on. Very inconsistent.
- Clicks and pops in the loop come and go while key is pressed. Often in a repeating pattern.
Note: Samplerate is 44100 and the wav files are not altered in any way prior to transfer to the MPC1000.
How can this be explained?
Could it be that the samplerate conversion/oversampling is poor in the MPC1000?

Hi Torsig,
What is 'Blue Box'? I've not heard of that.
The MPC1000 uses a VERY different sample engine to the S5000 and is not as sample accurate in the playback of loops as the 5000. It's fine for rhythmic loops, etc., where a playback slip of +/- a few samples here or there is likely to go unnoticed (and it uses a simpler interpolation than the S5000's which is a high quality Le Grange as I recall with dedicated hardware to handle it all) but the MPC1k wasn't really designed for this kind of über-accurate sample playback so I suspect it might not be up to the task.
Cheers,
Steve

OK, that means that there's nothing wrong with those Hollowsun libaries or my technique of converting them to MPC. Guess there's nothing much to do about this.
Do you have any idea what the situation is with MPC2000XL, which also reads wav. Did they use a more accurate scheme for looping or is it the same problem?
Thanks for the info anyway.

By the way. Is there any application (for Mac preferably but PC also) available to edit the note information parameters on Akai-wav files from S5000? There are three parameters on the S5000: "original note", "semitone tune" and "fine tune". On MPC1000 there's only one; "tune" and sometimes tuning gets messed up. The relations between these is not quite clear to me.

Small little app that seems to do what it's supposed to. I'm able to run it on my Mac using CrossOver.

I don't know but it wouldn't surprise me if it's much the same - these things are not really designed for playing back loops with absolute sample accuracy. The MPC4000 and MPC5000 are the only ones for that I think.torsig1967 wrote:Do you have any idea what the situation is with MPC2000XL, which also reads wav.

If you want an MPC editor for Mac, try Pad 187torsig1967 wrote: Blue Box:

Yes, that's a nice app but it can't convert S5000 programs though.hollowsun wrote: If you want an MPC editor for Mac, try Pad 187
Anyway, thanks for clearing up this whole loop situation for me. I know now that it's a bad idea to use the MPC1000 for looped sounds like stringmachines, organs and such. Maybe it's a good thing since Akai S5000 programs are more complex than MPC1000 can handle in many aspects and I would be disappointed anyway.
