Hello,
I've been looking for a music stand to attach to my accordion for a long time. Having never found one, I finally cobbled one together. I can attach an iPad Mini (7.9") or an iPad (10.2"), but it's heavier.
To use Piascore (or other software), it's really handy with a page-turner on the foot.
Can't figure out how to add photos to illustrate, sorry about that.
