I wouldn?t make a big deal out of it. Yes they will come out with updates that will address these issues. in the meanwhile, its best to report these "bugs" directly through Access Support, so they can start addressing these issues immediately, if they haven't already started.
Ben already posted a thread suggesting to report your issues through:

Also, remember that just about every synth manufacture usually follows up with series of OS updates that address these little knacks and bugs.
Part reason for that being that it?s almost impossible to test something in a real world environment, with every configuration and setup. Certain issues are sometimes compatibility issues with different hardware/software setups, but sometimes not... whether it be the midi interface or a USB chipset and drivers. There are just so many possibilities and sometimes impossible to test something under every possible situation. Being it's Access, you can rely on them responding with updates, as they have shown they are not shabby on the support end of things. If they still support their discontinued products (i.e. virus b), you can most definitely depend on them fully supporting the TI.
