shap, you said a lot of fascinating things, but most of them are nice thoughts for the future of electronic music, and have nothing to do with the current state of affairs in regard to hardware synths. Just starting with this assertion:
shap wrote:When synthesis relies on custom hardware, it's impossibly expensive to upgrade or augment a synthesizer in the field (that is: after it ships). If an upgrade involves sending you (the user) a new card, and requiring you (with some % success insured by warranty costs) to install it, it's damned expensive. Conversely, if an upgrade requires a software install, the expense is much lower.
I'll address this again with specifics, because frankly, I'm baffled as to what you consider "impossibly expensive." I bought a number of synths over the years which offered expansion. My first real serious synth was an Ensoniq SD-1 workstation, and when it hit the market, it had the original limitation of the VFX of 21 voices. Shortly after they produced it, they offered an upgrade which increased the horsepower and which gave the unit 32 voices of polyphony and some nice new effects. This did require me to ship the thing off to Ensoniq with a $200-plus check. In fact, a similar upgrade was offered for VFX-SD owners for around $670 which turned it into an SD-1. Let's say mine was $275. Considering that mine increased the synth power of an $1850 workstation by 50% and then some, and essentially gave VFX-SD owners a new instrument, I'm not sure the cost was all that crazy. Inconvenient, yes, but then this was the early 90s.
Roland offered sample library cards for their synths as far back as the D-70. I think they were around $120 each, and had around 256K of new samples. With the advent of the XP-50, they upped the ante to SR-JV 8 megabyte boards that cost about $180. With the Fantom series, it became the SRX board that cost in the vicinity of $200 and could hold 32 megs. All were pretty easy to install.
Yamaha had similar cards for their synths since the SY77 days, I forget the price, but basically had one instrument like sax or drumkits. With the Motif, it became synth boards like the AN-150 which cost around $175 if I recall. The forward thinking EX synths had user installable SCSI and Flash ram expansions, though I forget what they cost, but weren't "impossibly expensive."
OASYS offered software expansion on CDs or DVDs for around $120 per instrument.
My M3 was provided with some 256 megs of orchestral samples and the original 4 meg piano for free, as well as some free vintage keys. The 256 meg memory board is a hassle to install and is a bit pricey at $120, but "impossible?" A good pizza party can cost more than that.
OASYS owners are bumming because they can't upgrade their Os to be a Kronos. Sad but true, computer hardware has increased in power and complexity over the six years since the OASYS was created. The team spend that time re-engineering the OASYS engine to work with the new hardware, as well as Seamless Sound Transition capability. The hardware is completely different. The engine is far too different. So if you own an OASYS and have to have the new power of a Kronos, you'll just have to get a Kronos.
But how is this any different from any other synth manufacturer? The XP engine of the late 90s is pretty similar to the Fantom engine. But I guarantee you that the hardware in the first Fantom is radically different from the XP, and I sincerely doubt if you could even get the Fantom engine to work with the old architecture, that would fit in the rom space provided.
How about the Motif? It's hardly changed much since the days of the S-90
in function, but I guarantee you that the engine has been redone way more than adding some effects and articulation functions, nor is the internal hardware very similar at all. Heck, Yamaha became so confident in going rompler only for the XF that it won't accept any expansions at all but flash ram, which has irritated those with expansion boards who wanted to migrate up. Which of course required you to, dare I say it, but a new MoXF. And those guys I might agree with you are approaching "impossible" in cost, but then I'm unaware of any other non-KORG workstation with so much sample rom on board. The flash expansions are pretty pricey, maybe "impossible," but Yamaha has sweetened the deal by making their expansion libraries... free? Cheap? I don't know because I'm just not interested in an XF right now.
Let me go to the most compatible music workstation to what you're discussing - and which I'm remotely familiar, the Lionstracs Grooves. These guys are basically shells which host music PCs with a Linux Ubuntu OS with a WINE shell for Windoze apps. You can have as massive a system you want, with 6-core AMD CPUs and 64gigs of ram, and SS drives. Yeah, this is nifty and all, but it's up to you to load the thing with what you want as far as synths and sample players, even DAWs. And I hate to say it, but I'm just not that into soft synths right now outside of the Arturia softies. And guess what? No ethernet, even though it's essentially a PC.
There's the nEko, but I don't think it's a bit different. And the same guys basically redid the nEko right with the StudioBlade workstation, but it seems to be in the foggy realms off the radar screen of the music market, with units made as soon as someone becomes aware of them. And evidently only synth action keyboards.
I have NO IDEA whatsoever what upgrading either one is like. Maybe you could find out, but I have better things to do.
So... what you want right now doesn't exist for
anybody. Great ideas for the next gen of music workstations though, or if you should decide to make the next nEko on your own. Good luck with any of that though.
As far as I can see, we're going to have The Great Divide between PC based and Big Three + One (Kurzweil) hardware guys, with oddballs like Lionstracs and StudioBlade hoping for some attention in-between. But I can live with this, and so far it seems to be working okay for most people.
