A lot of clicks after sampling [fixed* for next release]

Today I had a bigger sampling session with my DT, over USB from the iPad, but also analog from an external synth. In every 2nd or 3rd sample I get nasty clicks at the beginning. The input levels are okay. I fear that this is related to the threshold function, resulting in samples that begins away from zero crossings.

Why on earth doesn’t the DT have any simple sample editing functions (fade in / fade out / crossfades) that allow me to fix my recorded samples? The DT is actually a great and well thought-out device. But the sampling section is a piece of crap.

You are aware that after recording a sample you can trim it and can zoom in very deep to locate the start / end on a zero crossing ?

Yes, of course.

Even the highest zoom level is too coarse to identify and repair peaks or to find proper zero crossings. This all reminds me of the SRC page, where the resolution of the start and loop parameters is far too coarse to find a click-free sustain loop.

'Digital drum computer and sampler '.

Its a drum machine first, secondary function is sampler. Drum sounds tend not to need much in the way of sustained loops. Its really disigned as a one shot player. Although it can be bent to do other things, there’s bound to be a trade off.
Sample cross fades, fade in fade out, are not in its feature set.

Also be mindful of your source sound, digitakt is mono only, so if you’re sampling stereo sounds, finding zero crossings is going to be a pain

If your generating audio on you iPad you’d be better off recoding on your iPad and editing on iPad … ignore the digitakt until you fix everything and then dump it.
Digitakt can do a few basic things but it can’t compete with many iPad sample editors

For fade in / out I’d just use the amp envelope

Your fear is, unfortunately, correct. It will also happen at the end of a long sample if you use the fixed recording length and the audio hasn’t finished tailing off before DT truncates the recording. only real way to fix it is export the audio back out and use a proper sound editor to soft fade the end of your recording.

All that and I still love DT! So convenient except for the few things which aren’t, but I can live with that.

Since the new engines and the option to set the duration of the sampling, the DT is much more than a drum sampler. Unfortunately, the sample editor has not been adapted to these new possibilities.

The DT records in mono anyway.

Tell me a way to transfer samples from iPad to DT and I will do it so. :wink:

Then the question comes up as to whether I should do the rest on the computer. :wink: Elektron should automatically add microfades at the beginning and the end of a fixed-length-recorded sample. Problem solved. I think it’s time to send a feature request.

Should always be optional. I don’t want auto fades in every situation.
But yeah it would be a nice option like on octatrack.

Yup, maybe it was once marketed like that but it’s no longer just a one-shot machine. It’s about one update away from being the perfect version of itself I think. We live in hope!

this is actually my biggest gripe with the dt

micro / crossfading would improve the workflow tremendously

Probably the same on any sampler where each track is monophonic / single voice … they will all instantly cut off the voice to start playing another

I assume new akai are polyphonic and priced similarly , more fx, synth plugins etc so if it gets super annoying there are other options.
I don’t think 1 note per track will ever change, I wouldn’t wait for it . Even basic micro fade would need 2 notes poly per track

I have been dabbling with DN inputs and wanted to sample for some exploration … what was throwing me was that the captured samples all seemed to have an artefact close to the beginning, but at what appears to be a uniform position … irrespective of the RLEN i chose - it’s like a short echo length following the capture start point

My simplification was to drone a simple waveform, filtered to low harmonics and i sustained it - it sustains without any change or any modulation and it’s fed (microfreak mono left) into DT which has no usb or midi connections

Afaict every sample i capture has this artefact not long after Fn+ Yes is used to sample

The preview makes it clear, zooming doesn’t quite show it consistently, but there is a small pixel clue in the samples waveform on DT - anyway, exporting it reveals that it is dropping two samples and this is the click that i experience (easier to hear on a low harmonic sustaining tone)

Can anyone compare this method to see if it’s a bug

this is time stamped at the place it keeps appearing when i sample with RLEN at 16 or longer 120bpm

i haven’t counted, but it could be spurious additional samples or just zeroed samples which were absolutely not present at the source

I have reported this now … I’m fairly confident this is a bug - there are other users discussing clicks and i tried my steps on a new project

It’s not every time, but the majority and always in the same location afaict

somewhere just under 176 ms … it is not extra samples, it is nulled samples in two positions

Thanks for reporting. I have a feeling that the clicking issue has something to do with a bug I found (and reported) shortly after 1.50 was released. The bug is bpm-related and does only occur when the RLEN parameter is in use.

click here too, at same position of 0.176

yeah - it’s already been fixed, it was related to the new ux settings which i speculatively called out only a minute before it was confirmed on the DT bugs topic, just a few minutes ago btw

Awesome detective work all - so it’s been fixed but the firmware update has not yet been released?

no idea of a date as of yet, but if they are not expecting too many bugs from a minimal update they might put it out sooner than normal, or may test other areas potentially affected - either way, the issue is fixed but there is no guarantee of a quick patch - with it affecting the core purpose of the device one might expect it could get released sooner rather than later tho

I would like to sample a few things directly to my DT and there they are, those clicks.
Is there any method you detected where this bug does not occur and one could sample just fine?

Unfortunately not. Sometimes you hear it, sometimes not. I think it depends on the audio material you’re sampling.
