Hello there, I am relatively new to chopping samples and have a hard time with it atm

When trying to chop up a song I always end up with chops which are a little mistimed, meaning the timing of the sample kick and my drum program kick are bad and you can hear both hitting after another.

Yesterday I wanted to sample a song which has 154BPM. When I load it into sample edit, the sample edit page displays a BPM of 154.16. Is this relevant since its slightly off? If its relevant, where do I change it preferably? Via process and then time stretch back to 154 and from there time stretch it to the Project BPM which in this case was 124 BPM?
I mainly wanna do sample based house music and sample old disco, blues and soul records. So I wanna end up with my sample being chopped 1 bar per row, so all snares and kicks line up perfectly on the 4x4 grid.

Can you guys maybe explain your best practice in chopping samples for me? Like there are several ways to change BPM and pitch it/time stretch it and I am getting slightly confused by it which to use when.

I hope I explained my Issue well!

I always check and lot of times manually adjust the startpoints of each chop. Startingpoint of each sample must be very precise and must not have any space before the transient of the kick, hat or snare that’s in the sample. When you convert the sample into a Non-destructive program you can also adjust the startpoints in program mode when things are still off.

What the edit page shows for bpm isnt really relevant as it’s not 100% precise. Loop the sample in sequencer at 154 and if it sounds good you know 154 is correct

But if it wasn’t you don’t need to convert to 154 to then time stretch to a different tempo. Just stretch it from its current bpm to what ever you want it to be

100%

Heavily relying on numbers :Sigh:
Forgetting they have ears. :Sigh:

Yeah I also adjusted the start points of the chops, but it didnt get me the desired result for like 2-3 times. Now I tried another sample and it worked great and improved the timing.

Ok thank you. First I thought the fact that it shows 154.16 is the reason why my chops dont exactly line up with the transients when I chop it via "region".

So you're telling me you hear the difference between 154 and 154.16? I thought the fact that the transients dont line up is due to the sample being slightly off its original BPM. I am still learning.
But thanks for your very constructive comment!






I wrote the first post bc I thought it has to be easier to chop and time stretch a sample to a desired bpm especially when I knew the original BPM of the sample.
But then I thought the fact that the transients didnt line up exactly may be also due to the fact that the drums where played live

Yes, if you’re chopping a break per bar and then replaying that to a locked grid it likely won’t loop perfectly for the reason you stated

Are you trying to layer other drum hits over a break? If that’s the case, chop your break up at every transient (kick, snare, hat etc) and create a new program with EVENTS. This will create a track with the break played out in the grid with each separate hit (kick snare hat) on their own pad. You can then easily layer each hit with other drums

Yes, I can, at the end of the loop/bar it won't line up and you'll hear it to.

Samples from music made without quantize (like Soul music) will not stay on beat perfectly, That BPM 154.16 or whatever is the best estimate & that's if the sample was chopped well at the start & end. If your just chopping by 1 bar you can chop each bar to the start of the downbeat of the next bar.

One way I used to do it is take a 1 bar sample into to seq & adjust the tempo until it loops nicely.

I suggest watch more videos on youtube of people making sample based house music; it sounds like u over complicating thing, you dont need to know the bpm of a sample for it to fit ur existing drum loop.

use ur ears and just play the samples over ur beat until u find something that fits, u dont dont need to be concerned with the sounds being perfectly chopped, just vibe until u find a groove

I notice when i do house i tend to only need 3 chops; but when i do hip hop i mostly need 4 chops; but i like longer sample so I can take advantage of the groove that already exits within the sample, and just redirect it to fit the context/tempo of the beat i am making.

Will try that! Thank you

So you chop 1 Bar into 3 chops?
Yeah, I tend to overcomplicate it, but I am also new and have ADHD so its naturaly that I overcomplicate it lmao. But all the posts in here were really helpful so far. I just need to practice more I guess.

Yeah thats what I already do. I am watching a lot of Malobeats, Tubedigga, Ricky Tinez and Ryan Makes Beats. Even though the first 2 are more into Hip Hop Beats.

Like to mainly chop each bar into 8 pieces then come up with as many different patterns as I can. This is also a good way to time-stretch the sample:



Nice, where do I know the sample from. I feel like I listened to a track with the exact sample just some days ago. But thanks for the Video will watch it completely later.

so not chopping 1 bar into 3

I was just saying thst if had a 10 second sample; I would copy the same sound to 3 pads and change the start points to different parts of the sample; then i will just play around triggering the sample over the drum pattern till i get something that fits.

and for house i tend to often end up with 3 pads of the same sample with diff start points.

while with hip hop i tend to end up with 4 pads, with the same sample at different start points but obviously that just a stylistic choice cos i dont like my sample flips to sound too choppy and rigid.

but like jaymack said i never look at the bpm of the sample as i would just pitch it and chop it and play by ear
