IMO there's one big difference when comparing Arturia and Access, which both make great sounding instruments. Well, there are problems with both, but sound is great and that's why we use them, don't we?
Both are quite small companies (at least if you compare them to Roland, Yamaha etc.). But the main difference is that Access have just one product (well, put into few packages) when Arturia has all those softs, hybrids and digitals and real analogs. I must say I've always felt that Arturia is so busy to do new things that their products remain half-finished. Origin included. I am not sure that this is finaly the most wise business strategy. Of course, releasing new products keeps Arturia in the headlines but there's a downside too: there's also growing amount of people that say "I'll never buy another Arturia product". Personally I am NOT saying that but I've read it many many times on this forum and elsewhere too. And as we say (at least in my country) bad news spread much faster than good news. I too have my doubts when thinking about purchasing some new Arturia product: is it buggy like others? Do they support it? How about hardware build quality? etc.
I agree with goldenanalog that with Access I have a feeling of continuity: their product(s) are made to last quite much longer. They aren't gonna release one product today and tomorrow the next one. Their business philosophy is Less Is More.
But time will tell what's the feeling of this small group of people here, Origin users. Are we left alone with dead product which is one unit after another getting more and more hardware problems and finaly we are told that there's no way to fix them. This is my biggest fear. I can live with my Origin(s), with these functions and features they now have, but it's the build quality which I am most worried about. Another thing is that I've seen how difficult it is to repair anything in a normal way. If an encoder gets broken you probably have to replace the whole board...
Well, after all these rather pessimistic thoughts, let's hope that Arturia will brings us some good news about Origin...
