For me in Cubase 9.5.20
95 Slots (FLS VST3)
8.0 - 89
8.5 - 89
9.0 - 88
Sometimes values changes by -+1 (dont know why 
)
Thank you for this tool!
Thanks a bunch for this. Very kind and generous of you.
Cheers!
- Cubase 9.5.20 84
- Sonar Platinum 2017.10 114
- Ableton Live 10 110
- Reason 10 66
- Wavelab Elements 9.5.20 110
- Finale 25.5 100
This was on Windows 7 SP1 x64
Cubase AI 9, Win 8.1 = 97
Cubase 9.5.20, win7 110
After removing items not used from Steinberg Components folder. That gave approx. +10 FLS
That’s quite a difference from what I got! My measurement was in an empty project with just one FX track. I’m new to Cubase and haven’t explored what’s in the Components folder (and I’m on the train to work now); could you give an idea of some of what you were deleting, please? Effects, instruments, other? Thanks.
Cubase 9.0.40 → 69
Control Room off → +2
using Onboard Soundcard (actually turning off the hardware integration for the UR242 in the mixer I guess) → +8
Cubase 9.5.20 → 78
Control Room off → +2
using Onboard Soundcard → +8
Ableton Live 10.0.1 → 109
Quoting Fabio from an older post
"…For the time being, those who have the problem can lower the amount of loaded dlls by moving some of the components out of the folder C:\Program Files\Steinberg\Cubase 9\Components. Of course, this applies only to the dlls which are not needed during use (eucon if you don’t use such controllers, video files if you don’t need video support, hubservice, etc - make sure to not remove any core component like Baios, the exception dumper, mediaservice, SamplerTack, stepdesigner and the VST files). This will allow for more plug-ins… not much more, but could help some of you.
euconadapter (support for Euphonix / AVID controllers)
hubservice (Steinberg Hub, without this, you will only see the Project Assistant, the Hub on the left will be missing)
omffilter (you will be unable to import OMF files)
video (all files, of course all video features will be missing)
vstconnect
…"
Of course make sure you don’t use any of these features
Great. Thanks for the info. I can get rid of some of those that I’ll never use. I might keep the hub for now.
Cheers
It will only disable the internet part of the hub not the browsing projects and setup part
I’m sorry but what is fls mean? It’s not amount of CPU threads ,is it?
FLS = Fiber Local Storage. It’s not really necessary to know what it means (I don’t) but only to understand that in MS Windows there are a maximum of 128 FLS Slots per process, and with respect to this discussion, Cubase takes up some slots itself then each unique plugin (VSTi or FX) can take up one or more slots within the Cubase process as well. Therefore there is a hard limit to the number of unique plugins that you can utilise in Cubase. I say ‘unique’ plugins because only the first instance of any plugin takes up the slots, after that you can use that same plugin as many times as you like.
I have problems because I have quite a large collection of plugins which I like to use within all my project (e.g. UAD, Soundtoys bundle, Arturia bundle, etc.).
It’s not one plugin per slot because some plugins take more than one slot, and the worst one I’ve found is Arturia AnalogLab2 which will take up 28 slots. Waves is the best for me because it takes up only 2 slots ever no matter how many plugins I use.
The 128 limit was designed by MicroSoft and it’s been there for many years. It looks very unlikely it’ll change so it’s down to the software developers to find ways around the problem. I personally think it’s only really come to light recently because Steinberg have dropped the 32bit bridge and therefore all plugins now take up slots on the main Cubase process as opposed to say 1/2 the plugins taking slots in the 32bitBridge process (at least, that’s what I’m seeing in my setup).
It effects every DAW not just Steinberg, and Steinberg have recently reduced the number of slots Cubase takes for itself so they’re being pro-active in trying to help the situation. They say this is done by dynamically linking the DLLs instead of statically linking them. Plugin manufacturers can do this as well, and some are doing this faster than others.
Hopefully the more noise about this subject then the more the developers will streamline their software in future updates to help avoid the limit.

Interesting and educational thread. Thanks to the OP.
Got 93 on Win 7 Cubase 9.5.2 after removing all of the unnecessary services. Any idea on how to get to 110?
Excellent. Thanks vinark!
Thanks a lot for the app. Was it so difficult for steinberg to provide us at least with some little tool like this a while ago in order to at least no wonder about some weird disappearing plugins when re opening a project ??
Thanks for writing that article Lucas. In that article you are suggesting: “increasing the number of Windows processes to run plugins (why not offering 5 or 10 additional processes bringing each their additional FLS capacity, with either manual or automatic configuration per plugin - like a CPU can have 10 cores, a DAW could have 10 Windows processes to run plugins in and then the FLS issue would be totally gone)…”
I think that already exists if you are familiar with Vienna Ensemble Pro. Each new Vienna Ensemble Pro instance gives you a lot of new (free Slots for Plugins and Virtual Instruments). Like in your example, you could use Analog Lab (which occupies a lot) just in a new Vienna Ensemble Pro instances, without loosing available Slots (FLS) in the main daw…
Cheers, lokotus
PS: I thought Komplete Kontrol would also be beneficial to this issue, but it does not help for more slots like Vienna Ensemble Pro does.
JBridge can also be used to give you another 128 or slightly less slots.
Mike.
It seems that adding to everything this is also system dependent
Running a project by double click, through Cubase shortcult or pinned to taskbar shortcut adds +2FLS
This way hub (“stripped” hub - without internet part) is completely bypassed which apparently needs 2 slots to run
