Thanks for chipping in Noel. And Brando :)
Erm... it works.
But, not in my original X2 Test project.
When I first installed X2 I created my test project and I used that to make sure that all of my soft synths and effects plug-ins functioned okay. There are now over twenty soft synth instances including most of the bundled Sonar synths plus Absynth, Battery, Tassman, UltraAnalog, Chromaphone, BFD Eco and so on.
I've also been trying out my upgraded Breverb plug-in. And not forgetting TH2 vs Guitar Rig 5.
I've still not tested everything yet, but I just thought I'd give R-MIX a go in this test project, and this is when I found it wasn't working.
I then tried it in X1 and found that it did work, despite the message that it was only licensed for X2.
What I then tried was opening my X2 Test project in X1. I got the usual message telling me that it might not sound the same. When I opened the R-MIX interface it didn't work.
I then went back into X2 and created a brand new project called R-MIX Test. I inserted just one instance of Chromaphone and placed some quarter notes for a couple of bars and then set some loop points so that I now have a constant sound source.
I then placed R-MIX into the FX bin of the Master bus. The interface opened and it worked.
So, I suppose that is good news, although I am still a little concerned that it appears to be broken in my original test project. If it has broken once it make break again.
When I have time I will copy my test project and then delete things one at a time to see if that "fixes" R-MIX.
In the meantime, hang fire, because I don't expect anyone to be able to emulate this on their system simply because of all the bits and pieces that are in my current test project. I'll carry on testing and see how it goes.
And to be honest, until I can think of an expressive and creative way of using R-MIX I may or may not miss it.
thanks again
