Does anyone use the mpc to record sys. ex. ?

I trying to record sys. ex. messages from my triton keyboard as well as other sound modules, onto my mpc 4000 ( so that I can load specific presets, effect parameters, ect. onto these sound modules with only pressing play on the mpc ). It works fine until I save the sequence to the mpc and turn it off, when I turn it back on and load the sequence containing the sys. ex. messages and push play on the mpc I get a message saying "midi buffer full" and I am unable to load sys. ex. messages from the mpc to my sound modules.
Does anyone know how to resolve this problem?

dunno ... but maybe your sending midimessages to your soundmodule and simultaneously back into your mpc .... causing a midicrash

have you midi cables connected from your mpc to your module and backwards again? is so disconnect the one goin back to your 4k! ... also check some midisettings in your module (softthrue for example)!

hth

if not ... tell a lil bit more

sorry .... double post ...

Thanks, but it's still doing it. I called akai and they said it might be too long of a sys. ex. message for the mpc to handle. I also called korg and they said they'll check it out and give me a call tomorrow.
But thanks anyway.

np - ... wasn't of help anyways

apropo large sysex files ... largest uploads i do from my mpc to my module are os uploads - they're over 1 mb - no problem! also for patch and whole bank uploads (they are smaller) i always use the 4k and it always worked fine ... (never did it with the new 4k os though - but also don't think that 1.60 has a problem with it!)

other possible things: its recommended to set the tempo of the sequencer very low when dumping sysex from and to modules - i normally set it under 60 bpm - but i often forget about it - already uploaded succesfully at 150 bpm too ... however some softseq guys using my module even recommend to set it under 5 bpm!!! ... so slow tempo ... and make sure that sequence doesn't loop

... and good luck

Hey, what's up altopiano? Thanks for your response. I was wondering what sound modules do you use, and do these modules send sys. ex. messages all in one line (linear) or in a list, because I noticed the triton sends it all on one line, while my roland xv-5050 sends it like a list each line at slightly different time locations, I think the linear approach that korg uses is the problem, but what I can't understand is why does everything work fine until I save the sys. ex. sequence and then reload it, and that's when I get the " midi buffer full " message from the triton.

and that's when I get the " midi buffer full " message from the triton.

I'm sorry, not the triton but the mpc.

Did the sequencer run when you recorded the data dump? (overdub or play+record/overdub?)

I can imagine that this would happen if you have recorded all data into one sequencer clock tick, because you inserted the data in step edit instead of recording it with play+record.

The MPC would than be forced to send out a relative large amount of data in a very short period of time resulting in a buffer overflow.

cheers!

Yes I recorded the sys. ex. messages by pressing record\play start.

i use a virus kb


and do these modules send sys. ex. messages all in one line (linear) or in a list,

the kb sends sys.ex - what i understand in a list! they're displayed in seq edit on the 4k! but what it sends depends on what i dump from the virus (single, multi, buffer, arrangement ...)

just checked - usually i dump arrangement - which contains 17 sysex rows - streams (dunno in english). i guess it are the 16 single programs (patches) + 1 multi pgm. they are all recorded at slightly different time ... so in a list

... are you saying that its workin fine on the roland? whilst the problems is only on the korg? ...from what i understand from your explanation the 5050 dumps similar as the virus does here ...

what i would do is
1. check all midi options on the korg ... and see what is there ... imo your problem sounds as if it was a korg-midi-problem ... maybe just one setting ... (.. dunno, maybe you must just enable the korg to receive/send dumps ... or dump them the correct way)
2. disconnect unnedded midcables when dumping - so when dumping from korg to mpc dump mpc to korg cable - whilst when sending data to the korg disconnect the one goin back from the korg to the mpc
3. slow tempo when dumping
4 set loop off on the 4k both times when dumping and sending the data
5. dunno whether this is relevant ... but when overdubbing-dumping and you have a count in on the 4k ... wait til the sequence is running - save is saver ...
6. same here dunno whether relevant - set synch off (midiclock,...) when dumping ...

can't think of anything elxe ...

good luck

damn, ... over 300 posts and still can't quote ... is there a way to quote better???

yes the roland works fine.

I tried all of this but it still doesn't work right, the only thing I can think of is that it must be something wrong with the way the mpc saves it's sequencer files, because I can get it to work fine until I save the sequence file.

You have to put a quote mark at the beginning and at the end of a quote for it to quote properly, ex. [/quote] blah blah blah.............. [/quote]
