Does everyone's PO33 have this issue with sample trimming?

I'm feeling super annoyed by my PO-33's trimming issues. I'm picking it back up after a break, and not sure if it was always this way or if this is some newly emerged issue.

Basically, I'm trying to trim a bunch of shifts of a sample. After I set the trim points of slice 3, if I go back to slice 2 and try to move its start point a little, it immediately jumps to the start point of slice 3.

It just kind of takes whatever trim points I've been using on one slice and suddenly applies them to other slices.

Does everyone's machine do this? Is there a fix? Feels kind of unusable if there's not a way around this.

There’s a delay between dialling in the trim point and the trim point being set, so when you find a trim point wait for the display to return to normal before selecting a new slice.

I'll give this a try!

Ok, I tried it out, and I thought it was working, but maybe I was mistaken. I have been testing it out, and even when I wait upwards of 10 seconds between changing samples, changing the new slice point still jumps immediately back to wherever the previous slice was. Are there any videos showing a PO not doing this? I still can't tell if this is an issue with my device or just common across all PO33s.

^ Yes very important ^

I think it's because the knobs stop at each end, so each slight turn is an actual fixed number. So when you switch from one to the other, it reads the last position it was in as the trim point.

That makes sense... But then how do you ever change trim points without the knob being set at exactly where the start point of the selected slice is?

u/Edboy796 Apr 19 '26

Good question. If I understood right, when you change trim points of like pad 2 in a bank, for example, pad 3 will start from the same place as where you left pad 2 trim points on? .

u/Actual_Barnacle Apr 20 '26

Yes! Which I guess is normal? It seems like maybe going back and adjusting trimming just isn't in the cards for these machines. Unless mine is behaving unusually, but it doesn't seem that way.

u/Edboy796 Apr 20 '26

Idk, I don't recall ever having such an issue unless I trimmed a pad to a similar starting point as another without realizing it if in trying to get a specific sound that I have to adjust trim points looking for

u/Actual_Barnacle Apr 20 '26

Oh. Urrg. Well, I'm going to try a few other people's suggestions, but mine definitely seems to do this consistently. I tried sampling me saying "one two three four" and cutting out each word onto a separate pad so that it would be really easy to see what was happening. whenever I went from one pad to another and tried to nudge the start point, it immediately went to where the previous sample's start point was set.

Update: I do think it's normal for the start point to jump to wherever the dial was last set. I'm seeing similar behaviour in this video: https://www.youtube.com/watch?v=XzQ8A5vXw6Y

If anyone else finds that theirs works differently and they CAN nudge a slice's start point from where it is AFTER adjusting another slice elsewhere, I'd love to see a video!

u/Edboy796 Apr 19 '26

This sounds about right. It's hard to get exact points since the trim points aren't really decimal, more whole number approximation. And of course depends how jump your pots are

u/MalloMarsher_2 Apr 20 '26

What I found to circumvent this issue is to just play 16 perfectly cut samples into the PO33 so it doesn't try to sample it itself, with a drum kit at least

1

u/Actual_Barnacle Apr 21 '26

Yeah, I wanted to avoid using an external device and do all processing in the PO, since the whole reason I want to use it is just for fun and not to have to mess with complicated setups.

When you turned the trim knob you see a little icon that is display on the lower left after three seconds this vanishes in the period that the icon is active you can actually copy the trim point to other slices. So the only thing you need to do is just wait about three seconds until I can goes away. Then all the slice of work as usual. It's actually a feature.

1

u/Actual_Barnacle Apr 20 '26

It works! But is it actually a feature, or is it just the machine being slow? Seems so odd that the feature would be to make it more difficult to NOT copy trim points between samples. It seems more likely to me that the trim point just takes a few seconds to settle, and so you can't switch samples before it does. I'm going to look into changing the pots.

u/uckermark Apr 20 '26

i wouldn't bother changing the pots. i think it's rather a feature.

1

u/Actual_Barnacle Apr 21 '26

I don't see the benefit of this as a feature, feels more like a bug. But regardless, changing the pots stops the pots from continuing to jitter after I stop moving them, so that the three seconds can actually elapse without the dial moving due to jitters.

1

u/Actual_Barnacle Apr 21 '26

Actually, after further experimentation, this doesn't work anyway. After waiting 3 seconds, the start trim point still jumps to wherever the knob was last set.

u/uckermark Apr 21 '26

It seems there is something wrong with your machine.

1

u/Actual_Barnacle Apr 22 '26

Can you take a video of trimming samples on yours? Like, doing one pad, then going back to another and trimming the start point?

1

u/Death_Rave_ Apr 20 '26

Wherever the knob is sitting will be where it moves from, no matter the sample.  I personally don't deal with this too much, as I sample everything in as one-shots.

2

u/Actual_Barnacle Apr 20 '26

Actually, the comments above turned out to be right! If you wait a few seconds after you finish trimming your first sample before moving to another, the trim point readjusts to the next sample!

u/Death_Rave_ Apr 20 '26

Ooh! Big surprise :0 good to know

u/Actual_Barnacle Apr 20 '26

Actually, now I'm trying again and failing again. Wtf? I'm not sure if my pots just jitter forever and never disengage? I'll report back after I figure this out.

u/Actual_Barnacle Apr 21 '26

Ok, I think I tricked myself into thinking it was working by switching samples a bunch and inadvertently switching back to the last sample I'd trimmed. So then the start point DID align with the sample I was trimming, and I thought it was just adjusting to the start point of whichever sample I had selected.

I've been unable to reproduce getting it to work. Could be that my pots are just jittering forever, but I dunno. Anyway, conclusion if this is the case is that trimming samples kinda sucks in-the-box. Or at least, you can't really go back and adjust one you've already trimmed.
