I was intent on using my BK7M with my Privia 350. Bk7M sits perfectly on the end of the piano but I kept it on the second shelf of my keyboard stand. Did it for one job and then fell into the BK9. Now its s neat practice and backup set but I do miss the real piano feel of the Privia..

One thing I didnt like was the extra wires needed, especially those AC Adaptors.
