Awesome! Thanks for those high-quality recreations, I'm looking forward to testing them out!
Samples doesn't have to be in public domain for me to work them, I'm fine with it as long as I can use them, also commercially, without getting sued. I've been making tunes for personal use for decades, but I'm toying with the idea of trying to get some of my latest work published, which is why I've gotten more concerned about these types of issues. Those pianos are an integral part of many of my tunes, and as such of particular concern and importance, so thanks again! If I do manage to get a release eventually I'll make sure to give you credit. I'll also credit the WaveWorld sample pack, since many of the samples I've used for years, which I was also a bit concerned about, were included in the pack.
My main concern, as far as getting things published, is the voice samples I've used. Not sure if Purple Motion got the sample from Batman cleared, but my personal versions of the tracks have a lot of samples with similar concern. I'm working on recrating them with other samples, which I've officially licesensed, and I'm going to try to create own samples where I can't find samples in the licensed packs I've got that fit the tunes' theme enough to work.
Apart from that there are still a couple of instrument samples I need to rework or replace, but I'm getting closer now, and will get closer still thanks to the help on this site, so thanks again!
