Postby mevla; Thu Dec 21, 2017 1:20 pm OB-Xd and loud pops

Hello,

After a few times I can attribute loud pops in the audio due to OB-Xd. For some reason, it starts to emit those. The current Bitwig (Linux) session had two OB-Xd instances (tracks) and everything was all right when suddenly one instance emitted loud pops that seems to bypass the audio system and go straight to the loudest sound that can be made. This also was reflected in Bitwig's VU meter for that track. As such, it makes OB-Xd unusable. System is Linux Mint 18. Bitwig 2.2.3. OB-Xd recently taken from DiscoDSP, 32 bit. The 64 bit version is not seen, not listed, by Bitwig.

I may add that I do use the system, with up to approx. 120 improvisations this year (about 100 for 2016), all multi-tracks, plus a few more serious projects. So when I add OB-Xd and there are loud pops, I can basically tell what is causing that since nothing has changed from the regular workflow of synths and plugins, which are after all, a limited choice in Linux. That the Bitwig VU meter also shows it just confirm the events.

Cheers.

Strange. Anyone else can confirm this? Does it work fine in Renoise?

I have the same problem in Bitwig 2.2.3 as well. I'm on Ubuntu Studio.
OB-X is the only plugin that does this for me as well.

P.S. I am using the 32bit version. I have not been able to get the 64bit version to work.

Ok, does this happen in Renoise too?

Well, I do not use Renoise.

No idea why the loud pops happen yet, sorry.

Maybe the 64-bit version does not behave like this, if it could run, that is. At the moment Bitwig cannot see the 64-bit version.

64-bit version works well here in BWS 2.2.3.

Haven't noticed any degraded sound.

Banks and skins load without trouble.

Local build from source code.

Best,

Did not build it from source.

Got it from DiscoDSP.

64-bit version returns error code 255 as reported by Bitwig.

I have Renoise. Only used it once to make a piece.

Using it now to verify the problem is pointless, as hours will be spent just for that, notwhitstanding relearning part of the workflow.

Hence, dropping OB-Xd for the time being.

OTOH, Repro-5 works nicely since the beginning.

P.S. Are there clear instructions out there on how to build OB-Xd ?

Cheers.

It ought to be simple as cloning the repo, run the JUCE Projucer on the OB-Xd.jucer file, cd to the Builds/LinuxMakefile directory, and running make there. Alas, now it doesn't work, I get a slew of errors. Maybe it's the JUCE5 I'm using now, I don't know, but like yourself, I've better things to do than track down the problem at this time.

However, if you're willing to check it out, here's the binary I built last year, which does work in BWS 2.2.3 here.

Let me know if it works for you, thanks.

Edit: Just a note to let you know I love those Waverazor sounds in your demo.

Best,

Our OB-Xd was built using JUCE 4. Upgrading to 5 is pending.

Unfortunately it does not show up in both Bitwig and Mixbus32C.

Waverazor is all right although it's darn easy at a twitch of a knob to seriously go into chaos. Serious taming to be done.

I have problems with other discodsp products in Bitwig. The popping with OB-Xd and random crashing with the Vertigo demo(was hoping to purchase during the sale period.).
Discoverypro is still quite usable, but I am unable to save presets. Luckily Bitwig saves the settings in the song, so not a big deal.

I suspect this will all change in the near future. I've heard rumors Bitwig are working on some/most of these issues.

Vertigo works fine here. Never seen it crashing and I used it for long periods. Linux Mint 18. It has some pretty good sounds on its own as part of the default soundset, especially in the pads section. It retains a certain simplicity while offering complex layering, which makes it easier to integrate in mixes. Some other synth pads are extremely nice when played on their own but require a lot of attention in mixing in order to keep what was awesome. And sometimes that's simply not possible or at least it asks for a reorganization of all the other tracks to go along with. With Vertigo the intricate layering is carried over in a simple and clear way I find. I'm mixing a session from 1 1/2 year ago now in which Vertigo has an absolutely distinctive sound. I don't know which one, as it shows '000 Memory' but it's very nice.

One drawback is that it will not communicate the patch name to the DAW (Bitwig).

The other drawback would be the lack of a scalable UI. If it could only be scalable to 150% or better 200% it would make it much more inviting to explore as this is the kind of synth that's not usual and needs some time to get into. A nice accessible UI facilitates that.

If these two drawbacks could be dealt with, it'd be great ! And maybe it could help getting new customers. Some HOWTO user guide on additive synthesis could be nice also, as this is not common. And of course, fixing any crashing issues.

Cheers.
