They're in an xp P4 2.8ht pc, I had built by an audio pc specialist in 2003 ish. Still works, and I have core 2 duo unit with 3x PCI as a spare pc incase this one bites the dust.
I've always loved the scope system, the synths are top notch, I love the patch what you want to anything else way it works, I love the FX. Has always felt like a piece of multi use hardware, rather than vst's.
But it wasn't really viable to have a latest and greatest PC with cubase 11/12 and still be used.
Since I've started to treat it like a piece of outboard gear, it's been 10x better. I go in and out of scope via adat, aes and spdif. I have it setup as external FX in cubase on some adat channels, the rest I use for instruments.
It's works perfect, everything stays in the digital domain, no latency, no stuttering, comprehensive midi control with a novation SL MK3 makes each synth really feel like hardware. I swear I've still not heard better, hardware or software and I've got some very nice gear.
I'd be absolutely gutted if these cards packed in. Wish I could locate one of those word clock adapters to really lock in clock timings with my new interface, but one might turn up on eBay eventually for a realistic price.
I'm running scope 5.0. I wonder if anything has changed sonically with 5.1 or later.
I can't believe sonic core still supported these cards with software upgrades for this long, they deserve some serious kudos for that.
I'm glad I got to keep my scope system. Because I ain't got a spare 5k for an xite.
