Hi Dave, sorry I can’t. I haven’t had any luck yet connecting my P121 to Smart pianist yet. I’ve been meaning to ask what type of cable are you actually using?

I bought a lightning to USB camera adapter from eBay ( but its generic) so hoping it might be the problem.
Went to one of the local Apple product sellers and asked about one, he said won’t work. Didn’t want to pay $50 and find out wouldn’t work.
Hoping he is wrong.
