Just some thoughts from someone who remembers the old days when synthesizers were first invented, hundreds of years ago....
In those days you had to set up every patch by hand, every time you wanted to use it. And if you had a patch from someone else it was on a sheet of paper and you had to set it up yourself before you could try it. Or sometimes it was on a photograph - people used to look at photographs in the music press using a microscope to find out what patches other musicians were using.
The modern way is elegant and simple and I wouldn't want to go back to the old way. In fact I find myself in agreement with Aymericf about using patches as a starting-point. I like to get ideas from other people's patches, then develop them into something new.
Although it isn't possible to transfer patches straight into the Origin, you do have the situation we used to have, where you have an instrument capable of handling the patches you'd like to use. Have a look at some Arturia patches and program them in by hand. If you don't have any other Arturia software, download the demo version, see how various patches were created and create Origin equivalents by simply selecting the equivalent modules. Then the fun really starts - try alternative modules and generally fiddle about. The Net's also full of patch charts for various classic synths you could explore.
It's not as quick and simple as just importing masses of patch banks, but it's still a lot easier than what people like me used to have to do in the early days, and it's a great learning process. You learn a lot about how patches are put together, and you familiarise yourself with your synth much more thoroughly.
