What a relief!
Not that it’s ever likely to happen again, but there’s something about this new generation of ultra lightweight keyboards we are blessed with nowadays (or at least our backs are!) that can be a problem…
You just found out how easy they are to knock over, and also you might have noticed how much more they tend to move when you play them hard (normal piano or B3 weight). This is only exacerbated by those x-stand type keyboard stands. They used to work decently enough when loaded with enough weight to stabilize them (like my old 45lbs G70!) but these 20lbs or so arrangers are so easy to move, knock over, bounce…
This is why I prefer the ‘leg at each corner’ type keyboard stands nowadays. No matter how hard I play my BK-9 it doesn’t move an inch. And an elephant could jump off it (lol) and it would stay right there. I can’t say that for x-stands and column type stands.
Many of us grew up playing pianos and home organs, behemoths that you could pound with a sledgehammer and they never moved. Maybe it’s worth moving to a type of stand that, although the keyboard is light as a feather, it is supported so sturdily it FEELS like those old behemoths!
Just in case you keep an elephant as a pet!
This is what I use…
