Cubasis 3 PDC broken

The Plugin Delay Compensation is unreliable in Cubasis 3, and several AUv3s are exhibiting latency.
To replicate:
Create 2 midi tracks with Classic Machines :1 kick 2 snare.
Add Toneboosters Reverb as a Send for the snare.
Then group the kick and the snare and insert Toneboosters Barricade on the Drum Group track.
Compress the sound and you get Huge latency causing phased sound. If you replace Barricade with Korvpressor even worse.
If you replace Toneboosters Reverb with Impulsation by Gospel Musicians you still get latency.
it is obviously a problem with Cubasis 3, as all the aforementioned work fine in Cubasis 2 and other hosts, and only exhibit latency in Cubasis 3.

Hi Simusic,

Thank you for your message.
As of yet, Cubasis does not offer plug-in delay compensation.


When do you plan on implementing it?
A DAW marketed as a professional product in 2020 without PDC :open_mouth: , do you realise how outrageous this is ? :imp:
And I don’t understand why those plugins work fine without any latency in Cubasis 2. Are you telling me Cubasis 2 has PDC , but Cubasis 3 doesn’t? This then is not an upgrade but a downgrade!

Hi Simusic,

If possible, please provide me with a short example (e.g. a Cubasis 2 and 3 project) that demonstrates the issue.
Please upload these via Dropbox or similar and let me have the download link via private message.

Thank you.

Best wishes,

I sent you all of the examples in private message as requested. Any feedback?

Thank you for providing us with the project files, which have been shared with the team.


Are there other iOS ‘DAWs’ which do PDC?


Any news? Will it be fixed?

Hi Simusic,

Thank you for your message.

As of yet, Cubasis does not offer PDC, which remains on our list for future updates.


So the latency issue with Toneboosters Barricade/Reverb is indeed lack of PDC? :cry:
Good to know it is planned, but you can’t advertise a DAW as professional without PDC. in Pro DAWs PDC is standard since early 2000.

There are things which can be done in “future updates”, and others really requiring an urgent quick fix.
This one belongs to the latter category for sure!

I have returned to Cubasis 2, for this and some other reasons, for the time being.
I like Cubasis 3 a lot - but it still has to become a full working product.

Hi jimknopf,

We are currently working on a maintenance update, which is planned to address several user issues.

Best wishes,

Cubasis 2 never had PDC either.

No matter if it is PDC or whatever: like the OP I have met more plugin problems, including latency issues, with Cubasis 3, than I ran into with Cubasis 2.

Looking forward to the first quick fix…

Hi jimknopf,

Is the Toneboosters Reverb/Barricade group lag issue fixed? Or does it need PDC? If you have it fixed then please release an update. I think as long as the most popular plugs work correctly you won’t have many complaints.
