Alhtough STEAM is on my fastest SSD Drive. A last gen M2 running at 2gb per second... Omnisphere 3 is taking age to switch from one library to another.
Even worse, switch from one category of presets (BPM and ARPS) to another (PADS) takes the same exact amount of time.
I have parted my third parties libraries between the Share folder and the User folder but no luck so far.
Anyone has the same issue?

 

Don't run your DAW in admin mode

 

Really? I'm gonna try it...

 

Not sure why. I have the legit on Mac and crack on windows. No issues with switching. Is your SSD external? If so, what model/enclosure/cable?

 

No change

 

SSD is internal. M2

 

check folder read and write priviledges, give full disk permission to omni.app and daw. try.

 

Can also do a check on ur hard drives in diskutility

 

the switch is instant here. something wrang their. ok drive is gen4 but still.something is eating up resources. run this : https://go.microsoft.com/fwlink/?LinkId=212732 -
Microsoft Safety Scanner. also the latest vc redist x64

I have done every suggestion and
Now this happens

 

Same here! I wonder what may cause it. I've had the legit Omnisphere 2 installed before and everything ran smoothly. When I made the switch to v3, I instantly noticed a massive slow down. Doesn't make a difference whether it's used in a DAW, or sthe standalone version.

 

O3 takes a bit longer to open for me as well. I get the UI square filled in white for a few seconds then it catches and appears. O2 never did that. No biggie. I figured it will be something fixed in future updates and I've still really enjoyed using it. Analog Lab used to do the same thing.

 

The lag is a common issue when you use certain Omni 2 libraries with Omni 3.

 

It's not the opening that is the issue. It's the loading and browsing librairies and categories inside those libraries.

 

10 seconds between librairies?

EDIT : Just tested with Omni 3 librairies... same 10-12 seconds lag.

 

You still have your Omni 2 libraries installed

 

All third parties yes

 

Try removing everything that is 3rd party and legacy. Just start with a fresh Omni 3. Test, then gradually add extra stuff.

 

When anything cannot be loaded while it's clearly installed, you should check the health of your SSD!

If it's a Samung SSD, you can check it with Samsung Magician [free],
but I recommend Hard Disk Sentinel Pro which works for all manufacturers [shareware...
or free if you know where to look at ;) ]

I once found out that one of my drives is almost dying after getting several file reading errors
and long loading times for games. I ran Hard Disk Sentinel Pro and it showed me a health
of only a couple % and an estimated remaining lifetime of about 7 days.



On that same day I bought a new SSD and transfered everything with TeraCopy as it shows
all the possible file errors that can appear when reading fails. I lost like 2% of my files from the broken drive
but saved 98% of them and after everything was done, all the files were loading perfectly fast again.

 

1. STEAM Database Indexing: Omnisphere's core engine relies on a database that scans and catalogs your entire library (including third-party stuff). If it's corrupted, outdated, or overwhelmed by folder splits, switches between libraries/categories (e.g., BPM/ARPS to PADS) trigger full rescans, causing delays. This explains why category hops feel identical to full library swaps—it's not sample loading but browser refresh.

2. Third-Party Library Integration: Splitting between Share (official add-ons) and User (custom/third-party) can confuse the index if paths aren't optimized or if there are permission issues.

3. System Resources: Even with your SSD, low RAM allocation, background processes, or antivirus scanning could bottleneck it. Omnisphere 3 is RAM-hungry for caching.

Rebuild the STEAM Database:

• Close Omnisphere and any DAWs.
• Go to your STEAM folder (likely ~/Library/Application Support/Spectrasonics/STEAM on Mac or C:\Users\[YourName]\AppData\Local\Spectrasonics\STEAM on Windows).
• Delete the STEAM.db file (or the entire Database folder if you're bold—back it up first).
• Relaunch Omnisphere standalone. It’ll prompt a full rescan (this takes 5-15 mins initially but should speed up switches afterward).
• Test library/category switches immediately after.
