its a bug. it started about 3 years ago with an os upgrade, documented on elektron-users. i have notified them a long time ago about it but elektron never replied or fixed it. its one reason i sold my mduw in the end. sad… i thought it would be fixed by now… best if you open a support ticket on elektron.se and help to get it fixed. cheers
So if the problem is the OS, it means that every user has this defect.
All users of the MD do this test and confirm the issue.
I will open a ticket, so I can direct the support to this thread.
After other tests,
any parameter applies a change the volume you have these crackle,
it happens even if you move:
Track Master Level
VOL
PAN
EQ GAIN
DYNAMIC GAIN
DELAY / ECHO Send and LEVEL
but does not happen, for example, on the parameters of the filters.
I’m really confused now,
I hope it is a bug and will be resolved soon by the Elektron,
I have already opened a ticket, but so far no response.
Otherwise, the second hypothesis is that my MD has something strange.
I would appreciate it if you do the test,
because I want to upgrade my MD with +DRIVE,
but if all the MD have this flaw, I do not know if it’s worth it.
gotta say your 2 sound examples sound pretty sweet to me!
make my speakers rumble and its probably the most surprising low end frequency i heared all day /7pm now here
i really do not know what I am supposed to hear … no pops, no crackles, sound stereo stuff…deep base… i really notice nothing strange from your recordings
yeah sweet if the sound intentionally has that upper frequency distortion…but on these settings it shouldn’t be there.
that’s the issue. all we should be hearing is a nice, deep ,smooth modulated sine.
I’m fairly certain this is not a bug that creeped into the O/S but has been a feature of the sound engine since conception.
The crackling is due to the low parameter resolution.
Edit:
It will be more noticeable on Low Frequency sounds. As the frequency becomes lower, the LFO (or simulated lfo by manually turning encoder) will be modulating the wave shape itself, rather than just the overall amplitude of the signal. By distorting the wave shape, you introduce artefacts in to the sound, such as clicking.
The octatrack has resolved most of these issues in the updated sound engine.
But you can still hear it, if you use the cross fader, which has a lower resolution (and no parameter value interpolation), from my observations.
If Justin’s theory is correct, then the Static LFO trick can be used to test the theory. I.e., the static LFO trick gives finer control of parameters. So “Static LFOing” the clicking parameters should lead to less clicking.
It’s a bit too late in the evening for me to try this out myself and I am kind of swamped in general but maybe some of you gents/ladies are up for it.
Can you provide the OS version and file does not have this defect?
So try it and communicate to Elektron to verify,
since I already have an open ticket,
where I hope they’ll give me explanations.
i think i have this, i mean i notice it just when lowering the volume. it sounds like low rez/quantized stepping to me, but also like dc offset maybe? i get the same effect on some 12 bit yamaha’s too…hasn’t really bothered me.
it’d be interesting to test if you can make the sound happen when the sound is completely filtered out, if both volumes cause it and if the individual volume levels make a different. it seems to me like it’s less if i turn the track level down, but i’m not sure.
I had another close listen today and have to agree.
You’ll notice that if your rotate the LEVEL encoder whilst it is pressed down the distortion occurs. This would be due to the LEVEL parameter jumping between values, in steps of 4, with no apparent interpolation in between.
hey, well i cant find the discussion after skimming through a few of the eu compiled pdfs its too exhausting. i can provide every os for the md dating back to around 2003 but i would not recommend loading some of the older ones as they are not entirely revertable according to elektrons advice. rest assured it is an issue that appeared in an early revision and was not fixed and is a bug. weather its repairable now, i dont know but if they havn’t fixed it yet there must be a good reason. sorry i can not prove my statement now as i sold my md a few years ago
