I've had my CLP115 for over twenty years and my biggest frustration with it has been the pathetic music stand. It has seriously reduced the amount of time I've spent playing because it just won't support anything but a very thin book of sheet music because there are no page retainers and it is not tall enough.
On several occasions over the years I've looked for an alternative stand but never found anything. I even considered buying a bigger Clavinova just to get a better stand.
Anyway I recently did a search again and for some reason found quite a few suitable looking desktop music stands. I bought a Theodore MUS53 and it is superb and does the job perfectly and has seriously reawakened my interest in playing as it supports my go-to book the Yamaha 50 Greats for the Piano.
Just thought I'd mention it in case anyone else has a similar problem.
Here it is on Amazon:
