Thanks Gero, it worked with an old dusty sample.
@docshermsticks said:
would it be possible to add a box to enter the root note of your sample
that would feed into the ‘base_freq’ field.
would give more flexibility than just restricting to A
I guess this would work but since you need to edit the sample anyway to make it exactly 6 seconds long, I don’t really think it’s necessary. I’m a bit reluctant to do any manipulations to the chunk since I don’t really know what I’m doing 
There might be a buffer length info somewhere in there and changing it could screw up the file in a bad way, things like that.
My dusty old sample was around 4 secs. something. And it worked.

Have you tried holding the key (and have the adsr adjusted so it plays out) ? For me that played some other random samples until the 6 seconds were full.
Oh damn. That’s what is happening. I actually shortened the sound to get a guitar stab. And I thought I didn’t crop properly. I even deleted the sample for an even shorter one. And when I got back in the Z , still a long sample. So my first reflex was to think that there was a bug in deleting samples. That is so funny. Thanks for making that process clear Gero.
Thanks for doing the code work gero. I’m curious–does the sample playback loop or is it just oneshot?
I tried and am only getting Oneshot.
Cheers,
Hi Minch,
we figured out how to do looping, there’s another thread. However the controls are pretty strange and we haven’t been able to produce a perfect loop, always a nasty click at the loop point so it doesn’t really make sense to add it to the tool. I’ve given up on the subject (twice now). Thead is here: UPDATE: Perl script to convert sound files into OP-1 / OP-Z SYNTH or DRUM samples
Cheers,
Gero

Hmm. Have you tried asking Teenage Engineering?
Have another query–have we worked out what the P1 and P2 actually do?
P1 is bitcrushing, P2 does nothing. No way to change it.
I contacted TE sometime last year and it took over 2 months to get a reply in which they didn’t even address any of my questions. I won’t be contacting them again; the one thing I’d ask for is my money back (yes, I’m super pissed by now)
That’s some bad news right there gero, you got rid of it? Without your site I wouldn’t have any decent samples on my
OP-Z. I had an op1 since the early days and if you were to compare what the op1 was when it was first launched to what it has become I imagine a lot of people might not have bothered with it. It will get better and more features will get added but not sure about this looping issue as I contacted them about looping options on the op1 years ago and nothing changed so I won’t hold my breath for a looping option and if it does arrive it will be very basic. Surprised and worried TE didn’t give you a bit more respect tho gero since their product relies on your work.
Sorry to open old wounds. It’s funny, I assumed that TE would be good with it’s customers–but considering that they are shit at meeting product demand I don’t know why I thought that (especially with the OP-1). Just for good measure, I will email them and see what happens and respond to you in 2 months.
They must have a plan, surely…everything else seems well thought out. Perhaps they plan to monetize sample packs… but they do allow people to produce their own visuals… hmm
Bitcrushing sucks.
I used to own a Novation Circuit–that thing evolved overtime with many quality firmware updates that really changed the function of the device… here is to hoping the same thing will happen to the OP-Z. I will note one cool thing from the most recent patch update–you can now increase the sequence length to 16 times the original length.
But yeah–we need some synthesis control. Maybe we can ask Cuckoo to have some influence?
Thanks Gero
is this still working? it wont download anything for me after upload on any device i have from any browser. i see the 1.1.27 update fix some issues with ready aiff files with out metedata. but idk if i still need to do this to get chromotic samples or not. ive already tried your method with out the upload and download of the add time make freqency.
This site doesn’t seem to be working any more (chrome on a mac).

It’s a real shame, is there any other way to convert < 6 second one shot wav samples into an aiff that will work on import to a one shot sample slot on the opz?
i believe they updated the Z a while ago to handle import WAV and AIFF directly
either way pretty much any audio program will convert wav’s to aiff’s as well
edit yea 1.1.27 they added this functionality

Thanks but… Just tried dropping a 4 second 16bit 44.1 wav into the tenth folder of the lead instrument (6) any it’s not showing up in configurator. I guess I must be doing something wrong.
It’s a shame samples are all such hard work. I love the portability and the sequencer but the sounds in the opz are really boring to me.
Sorry, I realise I’m now being that guy on a forum who’s a bit annoyed about a thing and gets mean spirited about a whole device, but it is pretty opaque on sample transfer.
I put it in the folder, it doesn’t show up in configurator, and the next time I attach on USB it’s not there in the folder any more, it’s been deleted.
The device isn’t failing very informatively! What am I missing?
I tried using the op1 drum utility to prepare my single shot sample as suggested here, that didn’t work either.
The disk absolutely isn’t full.
When I add a short sample into any of the ten folders in the Lead folder, it disappears. The number button to select it doesn’t light up when the unit reboots, and when I put the opz back into usb mode there is nothing in the folder, the sample has been deleted. There is nothing in the Rejected folder, despite the how_to_import.txt file in the root directory of the OPZ stating:
5. if any content was rejected, it will end up in a folder named
'rejected' on this disk the next time content mode is entered.
This is pretty mystifying, any help or advice gratefully received!
what does your import.log file say?
maybe some insight in there?

Ah didn’t know that existed! Informative in the sense that it tells me the sample has failed, but not why.
Raw wav, and aiff (created by op1 drum creator, as someone in forum said one sample in that makes something compatible as an opz synth sample) both failed, no clue to why. Both mono, less than six seconds, 44.1, 16bit. Wonder if anyone has any ideas? I really don’t want to manually re-sample everything I want to transfer!

Ah, odd. “Get info” in Finder on Mac said they were 16 bit but actually in Audacity they were 32bit floating. Exporting and re-trying at 16bit and they work fine. Sorry to be a bore!
