Sample BPM`

when i sample from my TT
my mpc doesnt seem to know the bpm of the sample
i go to the trim menu and hit edit
and when i scroll to time stretch area and hit the BPM button
it says my samples around 10


why is this happening?
and how do i time stretch a record sample from a TT

Guess in which document you can read about it in chapter 6...

I know you have it! I hope it helped you to understand how to auto load files few days ago..

If you can't find it in there, maybe your PDF readers search function can.

Edited: Information was wrong, but the 2 below corrected me so post edited.

When it comes to the MPC reading the BPM, I do not think it is a solid method or a foil proof way of doing so (the auto-bpm detect method through the trim function). I've noticed when I sample too low, and the waveform isn't well defined the BMP reads different then if I record the sample hot and the waveform is well defined.

I disagree with this 100%. The function is based on two things: the amount of "samples" in the loop and the number of beats in the loop. It makes absolutely no sense that the volume of the sample has something to do with it. If the length of the sample is the same, it will give you the same BPM regardless of whether the sample is clipping or completely silent (try it out with "silence section" if you have doubts).

The method is "fool proof" like mathematics is fool proof.

true.

The method is this

samples / samplerate = time in seconds (of the sample)

time in seconds / beats of the sample = length of 1 beat in sec

60 sec (1min cause we want bpm) / length of 1 beat = BPM



So lets say you have sampled a drumloop and it has 8 beats. After trimming the sample to these 8 beats the sample got 229320 samples and you want to know the bpm.

229320 samples / 44100 samplerate = 5,2 sec

5,2 sec / 8 beats in this drumloop = 0,65 sec

60 sec / 0,65 sec = 92,3 bpm

peace

ah ok, my apologies then.

Thanks everyone
let me ask yall this
when sampling what do you guys look for?
do you look for just instrumental riffs or chords
or maybe vocals that may be tuned up ?

stool samples r the 5HIT!






nah, jokes aside
I'm sampling now since about 2 to 3 years. so ther's def. a lotta people on here with a lot more experience than my humble self. However heres my ... um.. "advice"?
I used to mainly search for clean samples . (meaning: just drums, or just a guittar ,or just whatever and nuthn else). this mighta been a single shot, or a couple of bars worth..
BUT, if you don't have a lot of records you probably won't find that many "clean" samples. And its not allways possible to filter certain things.( like if you just want them horns, but you don't want the drums and all that other shit). So it CAN get kinda annoying sometimes..
Well NOWadays I see/ hear things kinda diffrent.
I listen to the "sound" of the whole thing, not so much the individual instruments but the overall sound and rythm of the sample. like when u was a kid and couldn't really tell the diffrence. know what I mean?
Then go from there. Go digging. use ur imagination. Use ur machine. . repeat..

-Nin is more advanced then me, im barely 5 months into learning the art of sampling. and like he use to do, I still find myself looking for clean samples, but when i can't find a clean sample, i end up taking sections that loop good to me, end up with about 10-15 chops, throw em on the 500 mute group em all and just play around with them till i get them sounding nice with the drums,

Last night (early this morning), I was on my balcony with a pack of new ports, head-phones and my 500 from like 1am - 4am tinkering around with drums and this sample, and STILL didn't get it sounding the way I wanted. so once I get off of work, I'll be at home tonight messing with it till I get a good rhythm

@Ronin
yeah some samples can be a pain inthe ass. others work easier.
I mostly chop anything into 8ths. that way even if it's a weird ass time sig (like 11/8 ... I really had that a while ago) you can easily make it work as a 4/4.. as you probably will, i asume...

PS:
likin ur choice of "workspace". sounds real relaxed

lol yea they can, the current sample im working with has some really decent parts but they arent clean, just when you about to get a clean loop here comes a violin, or vocals, or drums, lol im still learning so forgive me if i say i dont fully understand time signatures yet *throws up flame deflection shield* but i'll get there lol.

and yea, im a night owl, and felt like my room was cramping me so i stepped out on the balcony with some kool to mild air, my head-phone and the good ol 500. lol

time sigs are actually quite easy to understand. It's just counting really. and simple dividing.
in a nutshell:

4/4 means one bar devided by four. think of the metronom.

click click click click = one bare

now usually you have the Snares on two and four:

click snare click snare


8/8 means one bar devided by , you guesed it, 8
the hihats usually are on the 8th notes: H=hihat S=snare K=kick

H_H_H_H_H_H_H_H_
_____S________S___
K_K______K_K______


so in a 4/4 time sig you have 4 4th notes and 8 8th notes ( 16 16th notes and so on...)
in this case;
the H's are counting the 8th notes, the S's are on the 2nd and 4th, 4th note/ 3rd and 7th, 8th note
and the K's are on the 1st and 2nd and on the 5th and 6th, 8th note
the 5th, 8th note being the 3rd 4th note
that would be a boom boom bap. Get the picture?




now if you have a time sig like 3/4, that means that one bar is devided by 3. like a waltz..

In this case you can still just chop it into 4th/or 8th notes and make it a 4/4..


get it??

preciate it man! makes sense. lol it just shows u my level of n00bness.

@ -niN:

@ rraderbeats

did you get your BPM problem sorted??
