Clicking in sine bass/sub bass on the Electribe 2

KnowingWhatTheButtonDoes · Sat Feb 14, 2015 2:51 am

Im pretty new to synthesis and cant figure out if this is a general issue with making very low sine bass or if it is particular to the Electribe 2. Its like the phase is out (not starting at 0) and playing with the envelope only makes the issue MUCH worse.
Ive tried filtering but it doesnt make much difference (I guess cos it never will on sine waves)
Basically, anyone got tips on making loud, warm, very very deep bass tones? Think of the kind you can barely hear that hold up/glue together underground deep-house/tech-house tracks.
The Dapayk Solo demo has some nice examples in it.

I think it has something to do with the wave cycle not having enough time per note to finish a whole number of hertz. But what do i know?

I don't have the E2 yet, but it sounds like a typical case of a low frequency wave being cut off too suddenly (e.g. when immediately succeeded by a new note with no time for a decay to zero). Do you hear it at the attack or end of the sound?

Both. I realised its from trying to overlap notes, so yeah the new (overlaping) note is causing it. Solved, thanks.

It happens with a lot of sounds on the emx2 and is from the re triggering of the amp envelope, in my experiments, anyway. It's the weakest thing about the synth engine in this unit, for me.

Same here. It comes back to the glide issue, tie issue, filter/envelope re-trigger issues that Ive posted about before on here.
For those thinking about getting one, be warned, these issues can be pretty limiting.

Read my thread on it. It comes down to being in poly mode and having long release tails.

That said, although its annoying there are some ways around it.

Even playing legato in Mono mode can give you the same issue.
The Volca keys suffers the same problems, from having a single amp envelope working on polyphonic sounds.

I disagree. The clicking you can get on the electribe2 is nowhere near the volca keys. On the e2 is it very high pitched and completely noticeable. Also, the clicking on the keys is not due to retriggering, but from having a zero or short attack. That is of course standard across most synths. I think on the electribe it is due to the cpu load or possibly some digital glitch that could be remedied.

You may well be right.

One workaround I've been using for the clicks on subby basses is to use more than one track to let the note decay longer, you don't tend to get a click on the first note you play.

When I noticed that problem gets worse with the filter on/IFX/Amp EG, it made me wonder if it was CPU load issue.
Also its better in mono but that seems to be since its not playing the overlaping notes.
And thanks Roblabs for pointing me to your other thread, if I had seen it I wouldnt have started this one, its pretty conclusive i think.

Just got a second hand Electribe 2 last week, cracking piece of kit except for the pops and clicks! Definitely not related to the envelope as they occur even with a slow attack. And they occur on monophonic mode too for me. I can filter a bass sound out almost completely but can hear the clicks at the same volume, so annoying. Can't even see it being a CPU issue as I can reproduce it with a single kick drum sequence.

Korg really need to fix this in an update.

Hi Ghostly! Are you certain it's not an internal headroom issue? Is the volume of the part in question at a reasonable level, I use 75 ad a start point, same for pattern level...
Best to check these things as you say it's second hand so everything may have been meddled with!

Sadly not wasstof. I have just tried reducing the pattern level and part level to 75. Have increased the attack to 100 and still the popping remains. It's there irrespective of filter cutoff, filter type, etc. FYI the particular oscillator I am currently using is Subsonic (number 015) but have noticed this on other ones too.

And I would also like to state that this isn't limited to sub-heavy patches, I can even hear the clicks on simple saw waves too. Is my unit maybe defective? Is there a way of posting patterns so someone else can test?
