So is this a different issue the the multi channel problem the guys on the software forum are saying was fixed by the update or are there some system specific issues?
There was an issue with changing to multichannel mode in something other than 44.1 khz. This was an EZDrummer bug and happened across all of the platforms.
The other is where SONAR seems to not be prepared handle the 16 stereo outputs that EZdrummer2 has now when it is present in a project that originally had the original EZdrummer in it. I have not seen a report from users from any other DAW host where suddenly the host reassigns other softsynth inputs present in a project to EZdrummer outputs. I think it's fair to say that both companies are looking at this in order to fix the issue.
Personally, I only have one project where this issue manifests itself and I haven't changed anything in it so that I can check it to see if works as expected whenever a fixed is worked out by either company.
(Edit: I changed my first sentence because I had misunderstood the issue and I wanted to clear that up. Hopefully, I've got it corrected. I only use 44.1 khz in my projects so it was never an issue for me.)
