Sorry, Magica, but I'm NOT of the 'buy a new arranger every three years' school.
IF the arranger you purchase a) already sounds fantastic (and why buy one if it doesn't?), and b) is built like a tank (for durability), you don't really NEED to buy a new arranger for over ten years.
Sound-wise, there's very little that needs fixing on a G70, and only the reappearance of the Chord Sequencer, or a completely new, ground-up perfect design (unlikely from ANY manufacturer!) is likely to tempt me to spend big bucks AGAIN...
But in ten years time (or seven, actually, I've had it for three already), it will still be working perfectly... A computer-based instrument, especially at the pace that Dom likes to upgrade them, is going to be VERY unlikely to be able to run the latest OS and features that Dom comes out with. It's all well and good to say that you can upgrade the CPU, but in fairness, how many of us are trundling along trying to do cutting edge work on a ten year old computer?
Due to the complex subsystems, even if you CAN upgrade the CPU, the rest of the hardware dependent I/O (who knows if even USB2 won't be a 'legacy' interface ten years from now?) and other peripheral systems will likely be unsupported in ten years' time. In the meantime, of course, Dom will continue to tinker and change and improve the MS, but a lot of the new features will rely on systems that will not work on the original (circa 2008) versions of the MS. Linux itself will evolve, to use newer technology, and will be unlikely to run well on ten year old hardware (try running today's incarnation on a ten year old computer
)
So you have to factor in upgrading your computer components for as long as they will continue to work with the I/O, and just pray that that will not be outdated by the software and OS... Replacing the entire computer, I/O and all subsystems in the event of a complete shift by Dom to use newer technology is not going to be cheap.
In the meantime, I'm still plodding along on my G70, and probably have whatever the Receptor morphs into by then...!
I'd also like to point out that, yes, I'm still busy with gigs and recording schedule, but the few minutes it took to make those demos hardly made it impossible to do. OTOH, I didn't have to fight my arranger's built-in sound or styles to do it
That's kind of the point I've been trying to make for a long time. I didn't have to go out, buy a bunch of VSTi's, install them, troubleshoot them, integrate them into my workflow, develop styles for them, fine tune them, and THEN make a simple demo.
I simply turned on the G70, picked a style, and played... Basically what probably 95% of us here prefer to do, IF our machine is capable enough to do it. There are a FEW 'tweakers' here (I'm one, actually!), but I'm sure that, if the style and sounds are already spot on, no-one messes with it much IF IT JUST PLAIN SOUNDS GOOD...
So, don't worry about it. Turn on your MS, pick a style or two, and play something simple and beautiful. IF YOU CAN
My impression of the MS is that it rarely turns out to be that simple, and the fact that you claim time constraints in making a simple demo seems to bear that out. It's an arranger, dammit! It's not SUPPOSED to be hard work!
