well it's been YEARS since i logged on my forum account... it's changed a lot :)
i found this and couldn't resist sharing it with you here...
remember how SONAR 8.5 / X1 (ana now X2) while running a 64bit installation on a 64bit Windows, can't rewire to Reason 5 (because it is 32bit ONLY) and could only rewire to Reason 6 & Newer because they had 64bit rewire ???
well i found some German Video on YouTube, which gave a Japanese Link to a program that BRIDGES that connection :)
