why is it that when sequencing in 16 beats per bar (4/4) that there is weird numbers?

say i want a sample to run for a whole bar, i gotta make its duration end at say 384 =((24x4) x 4)) instead of 400, which i originally thought the duration time was a percent. then i realised for some reason the 1000 if you overlap samples it doesn't play the 2nd one that comes in (why is this) to fix this, i had to reduce its duration to fit the end of the time signature. and then i realised it wasn't a percent % but actually another fraction.

does anyone know what im talking about, i cant really explain myself well.

-> Manual, page 10

But,

MPC Resolution = 96 ppq (parts per quarter note)
4 quarter notes/bar

(96 parts/quarter note) * (4 quarter notes / bar) = 384 parts / bar

Yep, like Stephen said. Think of each beat (quarter note) being divided up into 96 "parts." (Or, 48 per half-beat.)

Don't confuse yourself by getting too mathematical! :)

Hope all this helps--Peace... :)

oohh
i see

i have to get mathematical, cause if i dont end a sample at the end of a beat, or bar and repeat the same sample in the next, the 2nd one doesn't play, does anyone know why?

Use your ears, not your eyes nor your calculator.
Don't be a robotic calculator, FEEL THE MUSIC.

Also try messing with the sequence's tempo to get the loop to fit.

ppq stands for pulse per quarter note i think...

Actually it stands for "parts per quarter note" but pulse works to.

I'm pretty sure it's pulses, it being an electrical signal consisting of (you guessed it!) Pulses!

Pulses works but it does stand for "parts per quarter note". It was a term refering to the musical parts and the musical community does not care about electrical signals. What ever works for you is what you should work with. Peace

What musical use is ppqn? It is only involved in sequencers, and sequencers count pulses. If anything, the parts came in to the non technical musicians, unless Brahms indicated how many parts his quarternotes had?

check all your settings regarding poly groups, and the sample ending with seq ending...(don't worry, it's not magic, but it is in the manual)

Manual, page 91:
    Sequencer:
    Maximum events - 100,000 notes
    Resolution - 96 parts per 1/4-note

At least, when dealing with the MPC's sequencer, it is parts per quarter note.

well I'll be, I still think the language shifted away from the early technical explanation.,

Google PPQN and see what the top searches say when they break it down.

Going as far back as Roland Din Sync (1978) it's pulses, but Both Roger Linn and Dave smith use "Divisions per 1/4 Note" and since between them they invented the digital sequencer as we know it, I guess it doesn't matter that much.

Even the actual midi spec calls it "midi clocks per quarter note" (24 being the standard then, same as din Sync. And Clocks are Pulses,

So as far as what it actually means, it means Pulses, or midi clocks, but Parts means nothing without reference to something, parts of what?

Parts of a pulse!!

My searches confirm that Parts is just what came into use for technophobe musicians. as the earlier you go back it all but disappears.

if you cut your samples properly to 384 yada yada does that get rid of the sample dropping problem or am i just dreaming??
