Let me begin by saying I absolutely sympathise along with your predicament, however that your ‘easy’ request for one thing to have the ability to learn out the parameter units is admittedly not so simple as that.
I would begin by organising a VM with the final model of macOS that may run these older variations. VMWare Fusion is obtainable free for private use.
If it can save you out the settings as patches, then there’s a probability the following model can nonetheless not solely open that patch, but additionally make sense of it.
This is not assured. Opening does not imply they’re going to sound the identical, sadly.
In the event you can’t open the patches in newer variations, then even when the VM model limps like a three-legged donkey on a cobbled road, you’ll at the least be capable to ‘print’ the audio stems from every patch/Midi observe, then import to your present model.
I haven’t got expertise with all the particular synths you could have listed, however I can parallel this to an analogous challenge I confronted some years in the past.
Some deep background…
I have been a author/muso/engineer/producer because the late 70s/early 80s. Within the 90s I semi-retired & labored for one of many main multinational musical instrument corporations. As such I had contact with all the main software program makers of the time – to at the present time I nonetheless have mates at a few of them. That, I am conscious, makes me pretty privileged. Nevertheless…
Within the mid 2k’s I produced & recorded an album for a report firm. Ten years later they wished to do a full remix & remaster of it.
The unique was completed on WinXP, utilizing a model of Cubase & plugins that had lengthy gone out of help.
With the help of contacts at lots of the corporations accountable for this large number of software program, I managed to get the traditional Cubase information & lots of the plugins transferred to a contemporary Mac – utilizing a home windows VM initially – & transformed to a usable format.
That took care of the songs’ “overview” & all of the recorded audio. A number of the plugins, nonetheless, not solely not existed, the businesses not in enterprise, their authorisation servers have been gone, so we could not re-authorise. [One of the developers for one plug actually sent me a cracked version of his own software to bypass this;)) Fortunately, many of these were replaceable reverbs & echos, simple time-modulation fx etc, that I could replace by ear with modern versions by other manufacturers.
For many of the plugs I was given authorisation codes that were good for all versions from old to current & access to all those different versions… but with all the will in the world, we could not get all the plugins to export/import as we went through each subsequent release version.
Some plugins, even having working copies of every version, we could not get back the original sounds. Not only had the file formats changed [which we were usually able to work through even if some took 4 or 5 major incarnations of the plugs to achieve it], however the inside ‘wiring’ of the digital sonic parts had modified. Even utilizing known-good conversions, the brand new plugs sounded completely different to the outdated ones.
I ended up utilizing a mix of newly transformed plugs & some ‘printed’ stems from the unique.
Nevertheless, we finally didn’t get all the pieces throughout & needed to recreate a few of it from scratch. The report firm vowed that in future, a part of the organisational backup course of for a recording would come with cling-filming the pc it was recorded on & storing it with the venture. [I don’t actually know whether they ever implemented this or what became of the strategy.]
In the event you ask properly, I am sure the producers of every plug will provide you with entry to older variations – however you continue to want a working VM to run them, to be ready for lots of labor, and supreme disappointment.
