mpc user question

Does anyone know how many quickly mpcs can handle midi in
data? for example i'm making max software that causes more
than 128 retrigs in a beat at fast tempos. Could an MPC 1000
handle this many sample triggers? Is there an upper most
tempo that these units have? Some of my other gear has been
reseting when i try this.

Cheers anyone.

you might be better asking this question here
because i'm not sure there are many mpc users on here

Actually in response the the original question I found that
the midi output timing in MAX left a lot to be desired. I'm
no expert in these things but the only time I got the
results I was after was when doing the sound synthesis in
MSP.

indeed i'm aware of the timing issues but sequencing will be
running at signal rate so it's ok. cheers tho, and yes it
looks like i should have proof read that one=] ta all.

that company i forget the name that makes those brilliant
sync/midi timing boxes that cost a lot and can shift timing
clocks, dunno if they are still in business, brilliant
product but costly (tho worth it)
well anyway, he did some mental tests with an oscilloscope
etc and found mpc 2000/xl came out one of the very best. i
think old atari or amiga was the best coz its totally
dedicated to the task as opposed to windows and all that
nonsense.
sounds like you are being very ambitious, good luck

What are you trying to do?
128 retrigs at fast tempo = ???? why only specify one
number, which is meaningless without the tempo?

I've got a mpc1000 and have never tried to do what you're on
about.
It may depend on the OS you're using. Basic akai OS is
pretty rubbish, I use JJOS1, but there is a newer JJOS2. I
don't know how these would affect it.

I have had a problem where the mpc "soft thru" strips sysex
messages, but sounds like this is irrelevant.

I will be using the mpc later today so I might have a play
if I can be bothered to work out what you're trying to do.
You might wanna try asking on the mpc-forums.com website.
There are some good people there (unfortunately a huge
amounts of dickhead hip hop bwoys too)

basically it's like a graphic interface for rhythm that
isn't based on step sequencing. i've got the interface done
& using max objects for the sample playback, however i'm not
keen on the sound quality of msp. I was curious what the
limits of hardware samplers would be to replace play~ and
groove~. the upper limit on the patch at the minute would
permit the equivalent of 128 notes played at 350-400 bpm at
which point other conditionals in the program are met. I've
had a peep in mpc-forums.com but there certainly is a lot of
bwoys there. does the JJOS has a maximum tempo? am i right
in thinking the step seq in JJOS is at 64th resolution?

thanks for your time.

128th*

sorry don't understand.
(a) Are you trying to trigger samples on a hardware sampler
from the computer via midi?

(b) Are you trying to use a hardware sequencer to trigger
samples on a hardware sampler?

(c) Are you trying to use a hardware sequencer to trigger
samples on a computer?

When you say step seq in JJOS, do you mean the grid editor?
There is a step editor, which is a textual interface with
each note denoted by the time it was triggered and then a
list of parameters.
The JJOS has a grid editor, which has 1/32 triplets max
resolution. You can tweak notes by more but not on grid
editor. In the step editor you can control it to 0.00.00,
i.e. 1.02.99 would be just before the 3rd beat on the first
bar. Hope that makes sense. Max tempo on my JJOS1 is 300BPM.

the actual sound of/with/from mpc's is not at all great

that's cool. I'm triggering via midi but i was keen to find
out the manufacturer limits. Some kit you can play beyond
what the user interface on the machine allows using sysex
etc but you can get bugs, I've had some things freeze and
reset. I know the mpc's are less than perfect machines but
they'd be an improvement on msp's sound quality
(personally). thanks for your help.
