No, this is really not true. You cannot copy all your keyboards into it as stated. The process of "copy and learn" is far over-hyped, and rather untrue. Allow me to explain:
When I bought Oberheim and Moog patches for my Kurzweil (when I was younger and naive), I did not really understand, but thought that those patches would be replicated on my Kurzweil. Well, it's a bit of a misnomer. What I got was a sampled waveform from an Oberheim or Moog, with various settings on my Kurzweil to sound like the particular patch they were selling.
You cannot manipulate the sound in the Kurzweil the same way you could with the original Oberheim or Moog synthesizer. What I got was one (1) distinct, particular sound which I could then use the technology in my Kurzweil to play around with. I did not get
an Oberheim Matrix-12 or a Moog inside my Kurzweil.
Likewise, Open Labs does the same thing, albeit a little more exhaustively with regard to keymaps. The "copy and learn" program will copy the waveform on your keyboard, and then also copy the keymap and strike points of that same specific sampled patch. You're still stuck with a single sound that you then have to use the Open Labs technology to manipulate that sound - Not a replica of menus and architecture of your original keyboard.
Another example to illustrate: Let's say you have a Roland synth with a morphing feature, where you slide a slider and the sound of a flute morphs into a guitar. Open Labs is not going to get that for you. You will have to program all the same desires of the sound morphing using the Open Labs menu structures. Makes sense? Just think about it.
Copying a sound is the same thing as a snapshot photo of a motion movie. An instance of a sound. It (the snapshot of sound, i.e. a waveform) has become the starting point of your new synth process.
Now, there are companies out there who have in fact recreated vintage synths with strictly software. But now we are talking about something completely different. You can buy a software version of the original
Sequential Circuits Prophet 5, for example. But this is not what Open Labs is selling you. Don't be confused.
