When this came out, about a decade ago at the time of writing,
it was revolutionary.
At this point, it's a small, dead end of evolution -
principally due to the developers inability to keep developing it.
With the advent of dual-core, 4-core, 8-core CPUs, and the support in audio hosts for these new developments, the money that was spent on (an extremely expensive) connectivity solution was better spent on new CPUs,
and FX-teleport, to an extent, became redundant.
Despite the developers continued insistence that they WERE working on a version 2, with support for multicore processors etc,
this never eventuated, leaving the frustrated users with a dead-end product that could only utilise a quarter of their slave machine's processing power.
In addition, many host developers, such as cockos (who developed REAPER) came up with their own proprietary solutions that Did support newer technologies, and supported them flawlessly.
In the end, the concept is great - the delivery dated, and now, 100% redundant, due to the developer's lack of delivery on their, decades-old, promises.
Avoid, and buy a better CPU - or a better host - instead.
I think the descibcion here is rather poor. What this does is, it loads your vsts on a second PC, so your Main PC is freed from the work and can run much easier and therefore more stable. You copy-install the vsts on your slave PC. Then you have a new folder in your DAW with the outsouced vsts, which you can use as if they were run from your main PC.
Not mentioned here : this is now freeware. So I installed it and well. I doesn't work with all plugins. But those who do work, work fine. It takes some time to get used to it. After that you can go crazy.. Load all the CPU guzzler you want (depending of your slave PC of course). You just want to ignore your electricity bill.
