I'm always happy to say to new or potential new upgraders, that the water is fine - jump on in.
You certainly can make any piano sound much different with all the tools in Standard and Pro (or save up for Studio for ultimate value, if you suspect you will want to collect all instruments). Plainly the best money I have spent on anything in musical life over 40 years. It's a modern miracle to me - after all the years putting up with really queasy MIDI digital products (excellent efforts for the era - so not just a put down etc) but now, Pianoteq is literally the only software piano I bother with.
Take a look at the Pianoteq references page - and you will see the word Grammy there more than 20 times - the list of genuinely stellar music identities who use Pianoteq is surely worth more than just my "yes, you can edit the heck out of it" endorsement I think Modartt is a sincere and modest group - but quietly this software has been progressing marvellously and hasn't stopped.
I've linked this in another thread recently, iirc the person was saying the U4 wasn't convicing..
anyway I think this sums up well, that the U4 (even version 4) is able to be bright, dark, convincing etc. and so on..

I'm sure that if you're loving editing you own unique sounds, this place will become a regular visit for you, and you'll end up with Pro before you know it. It is that good. I am you - a while ago - or was - or something like that
That's my personal and honest opinion and I'm here 'bothering' Pianoteq forum readers because other users of this forum first gave me good reason to look deeper into Pianoteq - and I am so glad I did - there really isn't anything else like it in my workflow.
Small, quick, editable in incredible ways - not limiting me to just particular vibe - remarkable diversity in all things to do with piano, as well as solid effects and excellent VST capabilities.
