Happy Holidays Dietz,
I found the original version of MIR PRO to be very stable on the Mac Platform except for one thing..... I haven't written a support ticket on it because I haven't been able to nail it down to where I can repeat it everytime. What I'm seeing is while using MIR PRO as a stand-alone with Cubase 5, every once in a while when I go to save a channel preset then try to reload that preset into a new VI Pro Channel, the preset is corrupt, the screen go blank and VE-PRO/MIR PRO exits the screen. I have to reboot in order to get things back in shape.
I didn't have hardly any instruments loaded at the time and was using very little memory. I ended up rebuilding the preset and everything is fine. When using the same configuration with Pro Tools, I never experienced the issue, just with Cubase 5. I've ordered an update to Cubase 6 thinking that the issue may go away.
Considering that your are coming out with an update, thought I'd give you a heads-up on what I'm seeing. I was going to waite until I had Cubase 6, then if I still was experiencing the problem, write up a support ticket. Not sure if other's have had this issue.
Take care.....
