Hi folks, I‘m new here and I‘m a great fan of the OP-Z, it‘s a marvelous device. Maybe I can help you further with the photomatic save pix prob. I‘ve got the same bug. I did different options, like the same way how eyescream54 and always the pix are not saved. And than, I simply uninstalled the op-z app and installed new and than — it works, like from ghost hands;-) all photos on my ipad device is still saved when I add it to the rolls and after closing the app they stay, too. It‘s a little buggy. Hope, TE will fixed soon. The same with your own samples import in a synth engine with a chromatic scale:-) (I think, this prob they must fix asap). Hope, I could help you further and maybe, it works the same way as mine, to uninstall and install the app new will fix the prob!
Best regards ?
