I'm using mine for Soundtoys and PSP stuff. I've been using Decapitator on the drum bus at 0x realtime and 4x mixdown OS and I'm not having any issues like that. Cubase 11.0.1 on an M1 MBP in Big Sur.
If anything crashes Cubase though it's definitely Metaplugin on my system. When it's open and playback I have to be careful to not close any plugin windows or it freezes and I have to force quit. If I stop playback I don't seem to have any problems. Also, it's pretty laggy on the controls when PSP Infinistrip for instance is open and the meters will actually glitch to static off and on during playback. Doing any type of 2x realtime OS is such a crapshoot I just have to leave it at 0x for playback. It'll be nice when all of the developers get on M1 native and stuff functions the way it's supposed to.

Thanks for the feedback.
It seems the issues are not only because of Big Sur/Apple Silicon, because I've got some (different ones) on Mojave.
I had more crashes recently too, so it may be because of Metaplugin (I didn't find the cause yet).

I'll try to run it without oversampling in realtime and see what it brings, but Decapitator doesn't sound the same at different sample rates, so it's not the best solution.
It should be better to have it working smoothly without being obliged to trick it...

Just in case anyone has missed it, Metaplugin is up to v3.8.3, which fixed some error with the OS algo if I remember correctly.

Also, someone sent me a PM believing I’m a representative for DDMF

Well, nope, I’m just someone who’s very enthusiastic about experimenting with OS and asked for these expanded OS features and greatly appreciate them.

I’m sure these features have ballooned the DDMF support inbox, but I am thankful that they created them for us.

I'm using the 3.8.3 version, but still has the issues I'm describing.

I sent an email to the support (and Christian already answered a previous email) but so far I didn't solved this problem.

It may be a problem with Soundtoys plugins rather than with Metaplugin, because I don't think I've got any issue with oversampling HG2 Black Box for exemple. If it's the case, I'm quite pissed off because I bought Metaplugin almost entirely for oversampling Soundtoys stuff (and more precisely Decapitator - and SPL Iron too, from Plugin Alliance)...

I can confirm that i have the same problems with Soundtoys and Metaplugin 3.8.3 on Catalina. Also Cubase 11 is freezing with Metaplugin i haven't properly tested it on Studio One yet.

Only Soundtoys plugins, or some other brands ?

EDIT : The funny thing is that it's not behaving badly all the time. I just opened a new Live set to test the behavior of Metaplugin comparing Decapitator with other plugins (PA SPL Iron, PA HG-2 BlackBox, PSP Twin-L), setting different sample rates online and offline.
I dropped a drum loop on a track, and threw it each 2 bars into a different oversampled instance of the above mentionned plugins.
I could set Metaplugin the way I wanted (OSX0, OSX2, OSX4, online and offline, IIR or FIR, set the latency), then save and open the session multiples times, without getting the issue mentionned above with Decapitator. Everything was running fine online, and the exports were ok.
So it's actually a very strange issue...

Logic is behaving oddly here too. When opening an instance of Metaplugin I get a short freeze of a couple of seconds or 5 and when saving Logic the whole thing goes weird and freezes for up to a minute before it gets its bearings and lets me even click on things and do stuff again. Not sure whether the saving bit is Meta (or my hackintosh needing a new buildup, which is definitely due), but it started after installing the new version and the plug freezes every time I open one which the old version never did.

Yes it happens mostly with Soundtoys but had a few crashes/freezes with other plugins as well.

I can confirm it’s not very consistent, sometimes it works without any issues and others it crashes immediately.

I had/have the same problem with Studio One (not regarding Metaplugin) where Soundtoys can crash it with adding/removing one instance and other times it seems to work fine, but it’s like playing Russian roulette.

I don't like current drop down menu of 2x 4x 8x 16x.

I much prefer older version's toggle menu.
It was not only faster to change OS rate, but I could have done blind comparison which is not possible any more.

Has anyone noticed that metaplugin seems to initialize plugin settings after an offline bounce or session close/open? I’ve tried contacting Christian about this and have gotten no response. So far this has happened with Uhe Repro 5 and Unfiltered Audio BYOME.

If you click on Set UI Colours and adjust the bottom left colour box to the same colour as the middle colour box, the logo will completely disappear.

oh I'm going to check that out ! Thanks !

Ahhhhhhhhhh! Thank you! That was so annoying. I wonder if DDMF can be convinced to set the text to at least something approximating the background by default.

To the serious users of Metaplugin, I've got some questions regarding the filtering choice after oversampling.

- Are you using IIR or FIR ?
- What are the pros and cons of each ?
- If I already use a plugin like TDR Ultrasonic Filter inside Metaplugin, what should be theoretically the best choice (most transparent) of built-in Metaplugin filter ?

I must admit I didn't test deeply theses options.
To me, quickly swapping IIR and FIR didn't sound much different (when using Ultrasonic Filter inside Metaplugin), but maybe I didn't spent the good amount of time and effort testing it.
And maybe I don't know exactly what to listen to when testing...

So I choose by default the IIR minimum phase filter so theoretically I'm saving latency and CPU processing.
But maybe I'm wrong and there are some artifacts I'm not conscious of...
I would be happy to have any feedback about that...

I prefer x4 oversampling, IIR and the Ultrafilter set depending on what sounds best on that source. Most often either light or that knarly curve. Just going by feel, as always. I just listen to where the thing lands in 3D space especially with the mids. FIR feels a bit less distinct for me. Bit soupy.

I think Ultrafiler of TDR(or Airwindows) works well when it's placed between two non-linear processor(inside metaplugin higher samplerate) rather than placed it last of chian. It would become obvious effect when these processors have more nonlinearlity.(e.g. overdrive pedal to ultrafiler to crunch amp).

It seems you're right : applying Ultrafilter last in the chain inside Metaplugin doubles the built-in Metaplugin filtering.
So it doesn't make sense to use it if you've got only one plugin loaded.
But it makes sense if you've got 2 non linear plugins (compressors or saturation units) loaded into Metaplugin to apply Ultrafilter in between.

Any opinion on the quality of the built-in OS filtering in Metaplugin ?
I don't know what to listen for in order to judge its quality. To me, it seems quite transparent (it doesn't alter the tone) but because anyway the oversampling is modifying the tone of the plugin I load into it, I don't know exactly if my feeling is right...

And I still don't know if the FIR is a better choice than the IIR. I don't hear any difference between them but I'm still on the testing phase and never used it in a real mix.
The linear filtering is supposed to keep the phase integrity, unlike the IIR, but does it come with side effects ?
Usually (depending on the source) I almost always prefer the sound of a minimum phase EQ compared to linear phase one... But if it's only a high-cut, I guess it's not the same...

DDMF metaplugin 3.9.2 fixed crash in ProTools when freezing/committing a track. Added plugin I/O configuration option.

I/O configuration so people can run mono version of a plugin and many more

Crashing a lot when im trying to scan au nd vst ?‍?

Fixed everything, im crazy hearing what i was missing wo/ this plugin on my vocal chains ?

Have a question, cla 76 its supported until 192, i work on 44.1, if i use x8 its on 392, theres a problem with that? I like how it sound ?

I never got a straight answer, but if it already internally OS's x2 (which many plugins do) then at 192 it's working at 384.
All I know is if I set the OS too high on render on some plugins it just gives me a blank track. I've tried it with amps as well and there can be a sweet spot as I was getting some nasty artifacts on Neural DSP Plini set at 8x render.

Updated the list with new information on oversampling.

Note: Most ADC chip will use an internal sample rate (fs) of 768 kHz 32 bit for sampling
when using outboard gears, then converted back to 96 or 192 kHz based on your DAW chosen sample rate.

Here are the maximum OS settings based on your CPU benchmark which also can be used
to record through plugins before fully reaching your CPU limits.

48 kHz (Mixing) SR:
2,500 = 1 x16 OS Plugin
5,000 = 2 x16 OS Plugins
7,500 = 3 x16 OS Plugins
10,000 = 4 x16 OS Plugins
12,500 = 5 x16 OS Plugins
15,000 = 6 x16 OS Plugins
17,250 = 7 x16 OS Plugins
20,000 = 8 x16 OS Plugins

96 kHz (Tracking) SR:

5,000 = 2 x8 OS Plugins
7,500 = 3 x8 OS Plugins
10,000 = 4 x8 OS Plugins
12,500 = 5 x8 OS Plugins
15,000 = 6 x8 OS Plugins
17,250 = 7 x8 OS Plugins

Attention!: Also don't forget to gain stage, as properly gain staging your plugin can prevent aliasing.

No matter how i tryit, ik multimedia amplitube 5 will not load into metaplugin. It will load amplitube 4 though. anyone experienced this?

No. I've been running Neural DSP and Amplitube 5 in meta plugin with no issues. The only thing I've encountered is that a few NDSP amps will distort unpleasantly if the OS is too high.

i finallly got it to work by opening folder location and drag and drop it in. for some reason it doesnt load under the scan

I tried it and it was crashing too often. What a pity that there is no alternative for oversampling plugin hosts.

There is definitely a gap in the market for just that one function (oversampling an FX chain).

Personally I think DAWs should do it natively... for example in your DAW channel mixer there could be Options > "Oversample Effects in this Channel" - and then have deeper realtime/offline oversampling settings in the main audio settings (IIR/FIR, 8x, 16x etc). They could get fancy and have send/return plugins but probably just as a mixer channel option would be seamless.

Ofcourse it'd take a lot of work for the dev to maintain because over-oversampling plugins that can't handle the higher samplerates can cause crashes.

For now, just like with Plugindoctor, DDMF are ahead of the game. Though they have their quirks...
