Hi. I'm going to purchase the Komplete s88 Mk3. I used to own the s61 Mk2. I had the Mk2 on a Z-type stand and found that, over time, a slight dip was introduced in the middle of the keyboard because there was no support at the center. Is the frame for the s88 Mk3 much more solid to prevent this or is it preferable to get a stand that supports the whole keyboard?
