Midi instruments go out of tune?
The first posts about this were back in April, but it was only two days ago that I experienced this.
When the instrument is loaded as a Stand Alone, it seems to be in tune, however, when it is loaded within a normal Cubase project it is not in tune. It is flat but not by a consistent number of cents. Some patches are worse than others. As it is, the instrument is not usable in a Cubase Project.
Other instruments may also be out of tune, I have to check further. HSSE is one the most important instruments I use and to have it be out of tune is studio-crashing problem. I can deal with a myriad of issues, but an out of tune primary studio instrument is something I can not cope with.
