Where can you report all defects found?

Where can you report all defects found in Cubase to be solved by the company? I personally found the midi with an external instrument (Yamaha Motif XF). In track editing midi notes are quantized but is poor playback (play delayed or anticipated). For this reason we have to continue working with them C7.5 because one project that needs to give it to completion. I think I discover many more editing software defects. Unfortunately I was disappointed by the market launch we tested enough by the company. We observed that users are those who test software.
