Hi, when I load the old project sometimes they says its missing plugins. I open the track and theys greyed out with the no way to auto-replace with the updated vst3 version. then I try to drag and drop updated vers vst3 over the vst2 it wont do its just adds it next to the missing plugin

 

good question. I recently had the same issue and never did find a "swap" solution

 

Not a swap as i know off . One of my big annoyance with ableton is vst , in general is crap compaired to cubase , scan takes for ever ,starts default on start up so you have to stop scan , used to be able to stop that but they removed that in a update and say if you got a hundreds / takes forver .

 

No and it sucks! There should be a vst2 -> vst3 tool in Ableton im not sure how other DAWs do this and some vst3s might not be exactly the same like their vst2 version but at least have a wizard that does try???? Should work without problem for 99% of the plugins anyway.

Loading time on my avarage PC with almost 400 plugins is excellent, takes a few seconds to open Ableton and scan is in background, but only if you install a new plugin anyways. What exactly is the problem with the scans?

 

It does sucks because I encounter these problem more now with so many updates I only can reinstall old vst2 version and try to copy over setting or save preset to rearrange to new folder so now need to keep 2 version for backup. Does the new Ableton 12 handle this different? I cant try the demo right now

 

For this reason I still keep a few of my essential plugins in vst2 installed as well, the synth I use almost exclusively and my favorite effects.

That way I have to dial in all eq and most stuff again but at least the basic synth and delay stays the same. Not ideal but what to do...

 

There is a way, but honestly it’s such a pain that I don’t think it’s worth it -- I'll share it here anyway.

.als files are basically gzipped XML. Inside that XML there are elements called <VstPluginInfo>, where Ableton stores all the info about a particular plugin in that project.

For example: let’s say I have an old project that’s missing the VST2 version of The Legend. I load the VST3 version into the project, then I open the .als file with 7-Zip, extract the XML, edit it in a text editor, and replace the relevant parts. After that, I drag the edited XML back into the 7-Zip window to overwrite the original.

Example:

VST2 (missing):
<VstPluginInfo>
<Path Value="C:/Program Files/Steinberg/VSTPlugins/Legend.dll" />
<PlugName Value="Legend" />
<UniqueId Value="1163154006" />
<Buffer> [BINARY PARAMETER DATA] </Buffer>
</VstPluginInfo>

VST3 (present):
<Vst3PluginInfo>
<Path Value="C:/Program Files/Common Files/VST3/The Legend.vst3" />
<Name Value="The Legend" />
<Uid> [4 FIELDS] </Uid>
<ProcessorState> [BINARY PARAMETER DATA] </ProcessorState>
</Vst3PluginInfo>

In this particular case, it’s easier because both versions of the plugin share the same UniqueId.

The key here is that the binary parameter data is actually compatible between the VST2 and VST3 versions of this plugin. So I just copied the <Buffer> data into the <ProcessorState> field.

So basically what I changed was:
- Plugin type: VstPluginInfo > Vst3PluginInfo
- Path: .dll > .vst3
- Preset type: VstPreset > Vst3Preset
- Added VST3-specific fields (Uid, DeviceType)
- Updated browser path and device ID

As I said, it's a pain, and kinda messy, but it works... "sometimes" lol

What about BlueCat´s Patchwork?

 

It can't retrieve a DAW projects' plugin saved state, if you had the plugin inserted directly in your project. Only if you started out with it loaded via Patchwork.

 

I wish I knew about the patchwork trick before. i have this same problem so often when revisit old projects then I need to find and download the old plugin formats reinstall and everything just to load it but then loses the settings and everything wtf. Its one thing I really dont like about Ableton. And also I wish they would allow using old version of stock plugins which in many cases were better than the new ones (ping pong delay im talking about you!). And the browser plugin scan thing is so f*&%&^$# annoying!!!!!! still its the best daw for the music I make so I put up with it.

 

An old studio saying goes: "If you're working on something, don't make updates."

I installed an old Studio One version 2 from 2014 for my 32-bit plugins.
I installed Studio One 7 for work and for all VST3/64 versions.
The idea is to adjust the folder structure beforehand and then install it in this folder.

 

I say it for years ... and Ableton fanboys always tell me they don't see the problem with Live "no real plugin manager" troubles.

OP : no, there is no way to auto replace VST2 by VST3 equivalent.
Open your old projects on older DAW, save VST2 presets and pray they are compatible with VST3.
Or just open old project on old DAW version and freeze the track (if you don't want to make adjustments).

 

Well, it actually wont do the trick in Ableton if that is what you´re saying...you´ll not get the preset loaded up with the BC PW.

FL Studio as far as i know will browse and find any of the plugin versions be it VTS2/VST3 and load it with the project preset.

Hi guys, I just released this tool (Ableton Plugin Fixer) that replaces VST2 plugins with their VST3 equivalents, and I was wondering if you could do some testing, especially with Blue Cat's PatchWork, which I’m curious to see if it works — If it doesn’t, please consider creating an issue on GitHub (or just report back here) so I can investigate and see if I can make it work.

It’s Windows-only for now, but I’m already working on adding macOS support, and a few other things.

EDIT: macOS support added

In order to avoid such a scenario I usually run a few tasks when a project is finished:
After finish, I render every single track in the project to audio with and without processing.
In Cubase this can be done very effectivly by saving naming schemes and other options as presets, that can be recalled every time again.
All these rendering tasks are put into a queue, that is processed in the background and meanwhile you can do some other things.
The whole bundle of exported tracks is then stored on a separat hard drive.

 

I opened the thread about it some time ago. It was about Melodyne after updating Windows 10 to 11. When v4 (VST2) stopped working and I had to use v5 (VST3). I tried to save presets in VST2 and open it in VST3 but formats of presets are different FXP and PRESETVST3 or so. I have found no way to swap plugins unfortunately.

 

That's another story, because here you are trying to open v4 in v5.
It is NOT related to VST2 to VST3 with the same version.

And you already created a thread about it, with a selected answer :
https://audiosex.pro/threads/celemony-melodyne-4-transfer-projects-to-v5.76241/

You need to save your v4 Melodyne PROJECT in each AL project.
Open AL, replace v4 VST2 by v5 VST3, and open Melodyne v4 in v5, and it works.

Of course you can't swap v4 VST2 by v5 VST3 ... because it is v4 and v5.
Totally different version.

 

@ItsFine Yes, partly, but I could updated v3 to v4 with no problems because they were both VST2. Even v4 VST2 and VST3 were not interchangeable.

 

this is another reason to name tracks with preset names and any info you might need.

 

Melodyne.5.4.2.006 = It functions as an Audio Units Plugin, a VST 3 Plugin, an AAX Plugin and a Standalone Application.

Welcome to the update case. A studio engineer once said that when you're working on a project, you don't do updates.

How great is the damage?
