Hi Bachus
REPLY
The biggest surprise is that you did not get a reply from Helmut of Wersi Austria, (Almost unheard of) try again with a basic e-mail, just in case your original got destroyed by a Spam Filter. (Alternatively post on the forum)
CPU
Current instruments use AMD multi-core processors; however you will need to order the upgraded version to run Komplete 5, as well as the larger hard disk(s). The Windows version that Wersi use, can accept up to 4GB of Ram, however due to the way the 32bit Windows system operates you will probably only get about 3.5GB max for your own use.
KORE
The Kore 2 controller can be connected via USB or Midi (USB is probably the least painful)
VST
To get the best performance, I suggest you use all 4 VST slots
RECEPTOR
This can be connected via Midi to your Wersi instrument (The Wersi has 2 independent Midi outs, each with their own sound banks)
VOCALISER
I am not a singer, so can’t really help there, however I have heard players using it, and it seems OK. (Most singers tend to use the TC Helicon vocalizes though)
OAS 8
There is still loads of potential to develop OAS 7 much further (Current version is R (Revision) 31) so there is no point in bringing out an OAS 8 version. (R32 is expected in the not too distant future)
UPDATES
We are promised an 8 track Studio quality audio recorder in the future, (Which I assume will replace the current Hard Disk Recorder and CD Burn modules) and we are also overdue for a big update in the Open Art Arranger (Users have reported various buttons have appeared in the OAA which as yet serve no function)
88 NOTES
The only 88 note board that Wersi produce is the Giga Piano
Hope this helps

Bill
