So a while ago I discovered by accident that some of the plugins that are now on the Legacy menu, like Drums, Guitar, Tuned Percussion and other are actually like a simplified version of EXS24. Yesterday I found out that other plugins there like the Analog Mono, Analog Swirl, Digital Stepper and others are a simplified version of the ES2. There's also the Clav which is the Vintage Clav, the Electric Piano which is the Vintage Piano and the ToneWheel Organ which is the Vintage Organ.
The Church Organ, Hybrid Basic and Hybrid Morph seem to be unique, as I tried to find the synth that opens when I tried to replace them, but no success.
That being said, if you still have the presets for those legacy synths, you can use them. Here's the list of compatibility:Analog Basic = ES2Analog Mono = ES2Analog Pad = ES2Analog Swirl = ES2Analog Sync = ES2Bass = EXS 24Church OrganDigital Basic = ES2Digital Mono = ES2Digital Stepper = ES2Drum Kits = EXS 24Electric Clav = Vintage ClavElectric Piano = Vintage PianoGuitar = EXS 24Horns = EXS 24Hybrid BasicHybrid MorphPiano = EXS 24Sound Effects = EXS 24Strings = EXS 24ToneWheel Organ =Vintage B3 OrganTuned Percussion = EXS 24Voice = EXS 24Woodwind = EXS 24
What that means is that you just need to drag the presets, for example for Analog Basic into your ES2 folder and you will be able to use those presets. There are some cool sounds in all of them. And that also applies to Piano presets open with EXS24, etc. Just follow the list. Again, Those 3 red ones, I think they are unique and there's no way to replace them.
Even if you don't have those old presets, here they are (I renamed and created new folders to make it easier to find the replacement):
Hope it makes sense and that it's somehow useful. I loved having a few more presets for my good old ES2
