I would like to create some single cycle and longer loop sample chains for the Digitakt 2. I created all the cycles correctly (exactly the same length and pitch) and loaded the joined samples into the DT2. The problem is that if I want to loop the slices, I can hear that the length is not exactly right so there are some artefacts and pops with longer samples (for example there is a buzz hearable with the sine wave because the loop is not correct). The strange thing is that when I load these as one shots, and loop those one shots they sound perfect. Every one of them. Any ideas why the GRID machine is creating a different sized loop?
You should ask @brian3kb in the digichain thread if you haven’t already. He’s very knowledgeable about troubleshooting sample chain / loop point issues but he’s busy, so he might not see this thread during the workday.
I think the first thing anyone will ask is what sample rate you’re using.
In my experience, single cycle waveforms work best when the source files sample rate has not had to change (or has ever been changed previously).
In DigiChain, ensure the working sample rate is set to 48kHz, and that your source waveforms are also 48kHz, as changing from 44.1kHz up to 48kHz means sample rate interpolation needs to happen to create samples that don’t exist in the 44.1kHz rate - this is generally where the clicks/pops come from.
Also, when preparing short/single cycle waveforms, turn off the de-click option in the settings panel, this ensures the waveforms don’t change their size due to declicking op, as its crucial all are exactly the same length in samples in this usecase, otherwise, again, there’s the chance of a sample changing length which means all the other samples get padded to match the length to ensure the chain fits the grid exactly.
Hey thanks for answering (and also huge thank you for the editor!). The sample rate was already the same (48), and the de-click option was turned off. I’ll experiment some more to see what changes would help. Thanks!
Also worth noting that Elekron says the Grid machine slices into similarly sized segments, rather than exact slices, which to me seems to throw off single cycles that don’t start/end on a zero crossing.
Hmm still no luck. I tried everything I could, even editing single sample points in Audacity to ensure they start at zero crossings. The Triangle and Sine waveforms keep buzzing, no matter what I do. Anybody with more experience who can help with this? You can find the SCW’s I would love to put into the GRID machine here: https://we.tl/t-DnWBYDiQ1m These are just 8 basic waveforms.
I realize this doesn’t solve your problem, but the factory wavetable WT Morph Classic is a 64-wave wavetable interpolating between the basic waveforms that you linked to (Morph Sweet and Entertainment are similar).
Also, I’m pretty sure these files created from the Adventure Kid collection in DigiChain work (though they’re in like D4 +10c) on DT2 if you’re looking for a basis for comparison…
You can get around the tail of the sample getting mixed with the next slice by creating a doubled slice, so for 8 slices that have been doubled, set the grid to 16 and choose odd numbers.
e.g.
However, this doesn’t fix the bug of the DT2 that has so far kept me using the DT1 until we get a firmware update to fix, and that is the sample trigger click on every damn trig of a sample, it happens on most of the stock samples too, its an audible pop, most noticeable when using the slice grid, but its on one shots too. (If you put that WT Morph Classic into a slice grid, you’ll hear the click at the start of each trig on that too).
My DT2 is still shelved until the next firmware update, I’m feeling that if the next update doesn’t fix the audio issues and bring overbridge support then I’ll be selling it on and sticking with the OT.
I’ve been working on something other than digichain the past month or so, and I have young kids, so the summer gets taken up with keeping them entertained around work!
Elekton please fix this. its makes impossible to use digitakt 2.
Almost all time i have this clicks in grid machine. cuting atack not helping, and its clicking even when i set volume on 0. couple of my friends have same issues.
Anyone know if elektron know about this problem? Shuld we made more tickets?
I’m pretty sure they know about this problem. They solved it on DT1 (by splitting at zero crossings) but they didn’t bring it to DT2 for probably a couple of reasons
it has unwanted side effects like pitch changes (because the timing is no longer accurate)
simplistic zero-crossing search wont work for stereo (in general, both tracks won’t cross zero at the same time)
What they’re intending to do about it, though, I don’t know. However there was this comment recently
My comment about the livestream wasn’t related to snapping, clicking or zero crossing. It was about the global setting for send effects.
AFAIK Elektron have been totally silent on all the issues with slices and looping samples. I think they know they’ve got a serious problem on their hands
No. Here is a 64 slices sample with sine wave. You can download it and make tests with Digitakt 2, 64 slices grid : you can loop and change slices without clicks.
BUT there is a click at the begining that also happen with One Shot mode, using a single cycle sine. THIS is an issue.
GRID doesn’t seem the culprit if sample is properly made. Check by yourself with my sample.
But, most samples aren’t just sine waves or specially prepared for use on the DT2.
Being able to cleanly loop arbitrary sections of audio samples regardless of their source or preparation isn’t a big ask for a £900 sampler in 2024, my Amiga 500 could do it back in 1992
