Hi,
I know, the following information is going to make you unhappy, but… In fact, it was a bug in some versions, where the Undo was working for the VST Instruments. Only the VST Effects should be listed in the Mixer History, by specification.
Therefore I would recommend to make a new feature-request thread.
Thanks for clarifying, Martin.
There are several things, this being one of them, that outweigh the benfits of C13 for me. So I will stick with C12 for now and keep my money.
I have the feeling it makes you unhappy as well…
How is an additional feature which works perfectly called a bug and is therefore removed again?
Thats really sad.
Thank you anyway for clarifying Martin!
Does that mean there is no undo stack for VST instruments according to these specifications?
Hi,
Exactly.
Well that’s not great, is it?
Well, there was apparently. lol
Hi,
Yes, there was the option. And it was a bug.
A bug?? It’s crazy that in 2024 it will be called a “bug”. It’s like saying that it’s a “bug” that Cubase emits sound. It is a common feature that any daw has, in all it would be that it was an undocumented operation. Ultimately I think that if it is a bug the developers should have a minimum of common sense, add documentation about the feature and leave it. It seems like bureaucratic thinking. It will make all users that use VST instruments unhappy.
This is easily the biggest issue plaguing cubase for me currently. It obliterates workflow having to basically A/b every instrument tweak 
I´m having the same problem, cant undo VSTs parameters change in CB13.0.20.
Is there any update on this? I’m experiencing the same undo bug with all VSTi’s using Cubase Pro 13.0.30 on Windows 10
Apparently Steinberg considered the ability to undo VST parameter changes as a “bug” and this ability has been removed in Cubase 13.
I’m confused, I don’t understand how such an extremely handy, useful, dependable and reliable feature could be a bug.
Will the vsti undo feature return to the program in another place/form?
Would it be futile to make a feature request thread for this to be implemented again?
Lol…the feature is a bug. No wonder there’s a mass exodus. Word in the industry is Steinberg has fumbled the bag with 13 and an inability to understand the needs of a shifting & increasingly younger customer base.
Sadly.
It is frankly embarrasing.
We better not have to wait for a paid upgrade for this functionality to be restored as a “feature request”…
A mass exodus? You mean the exodus TO Cubase, right? 
Really, do not let your personal social bubble fool you. There is no such thing like “a mass exodus”.
That being said, I agree that the VSTi history should be included into the mixing history. But there is not need to make a drama out of this omission 
Isn’t the underlying problem that UNDO for a Cubase project is not as simple as unwinding what you just did, but wanting granularity?
Scenario - I bounce a track, potter off and start doing some editing. Say it is a vocal track and I am editing a matching doubled track and I’m doing it by hand. 2 minutes in, I realise that a messed up a comp so I want to undo the bounce, redo the comp and re-bounce, leaving the 2 minutes of other matching in place. So here I want a track only undo.
In another instance, I am trying to balance a mix by altering several effects across several tracks. I realise I have gone down the wrong path and want to undo all the VSTi rack settings I’ve just changed.
As I am building a track, I might be editing MIDI. As I develop the track, I realise that I want to alter the instrument to audition the track and carry on editing. A bit later I realise that I preferred the original sound. I’d like to go back to the original setting in the VST instrument without altering the MIDI.
Basically, as I see it, there are defined units of work and each individual unit should have independent UNDO functions. So it should be possible to undo VST instrument changes (though this might be functionality driven by the VST stored within the track), it should be possible to undo Rack changes (should a track rack be an undo scope or just the individual rack instance), the track data has its undo scope. I suppose there could be a global UNDO that drives the UNDO of the individual changes, and any UNDOs applied independently have already been lost and cannot be reapplied by a re-do. Potentially, track data undo could be applied to multiple tracks in sync by selecting multiple tracks.
I’ve been using Cubase for several years, and my strategy has been track versioning, but then as far as VST settings, instrument and rack, I’ve not really had a strategy for experimentation aside from saving the project then reverting to the last saved version. Now, that’s not to say that there aren’t strategies I don’t know about or use (I find the AB in VSTs to clumsy as it is really easy to lose track alter the wrong version) but it is clear there isn’t an overall strategy for reversion so it is something I don’t use and occasionally wish was there (classic example, mixing up settings in similar racks on similar instruments where I daren’t try to use undo because I don’t know what it really is going to undo).
Currently, there are two “undo stacks” in Cubase/Nuendo: 1. project undo and 2. mixing undo. The problem is that the VSTi (instruments only) changes are not saved to either of those two stacks. So, either a third stack should be established for instrument changes, or those changes should be saved into the mixing stack. That is all 
Not social bubble. The largest Studio in the southern hemisphere 301 (Kanye recorded runaway there)
Sony music Aus
Universal music AU…I’m think that’s more appropriately the professional industry…Not a social bubble lol
If it is then my social bubbles are filled with highly influential people to the future of music.
And the consensus is Steinberg fumbled bad trying to release with everyone else.
Now they could jeopardise the entire future of Cubase.
