Hello everyone!

I just registered at KeyboardsForums.com and because it seems customary here to introduce oneself, I’d like to do that now.

During my school years I had continuous piano lessons, though with modest motivation and a very understanding piano teacher. Once professional and family life began, music and piano somehow slipped out of reach. At least, after our daughter was born, I bought a Yamaha PSR-220 keyboard, which was always unpacked at Christmas, where I could score points as the “pianist” during family sing-alongs. After New Year’s, however, it was usually all over again.

The years passed, then came Corona and the home office era. By now our daughter is grown up, and the former children’s room had space again for something new: it had to be a piano! I bought a used Bechstein N12 and haven’t regretted it for a second. It’s a little walnut treasure from the 1970s, still in good shape, and a source of constant joy and challenges. These days I’m playing Mozart sonatas again, which I once managed reasonably well, and occasionally I start something new. At the pace I’m progressing, my sheet music will easily last me until the end of my life.

At the moment I’m entirely self-taught. But if anyone knows a good piano teacher on the western outskirts of Munich, or is a piano teacher themselves, feel free to get in touch! Weekly lessons would be too stressful for me right now. What I have in mind would be more like monthly coaching, if such a thing exists.

There’s another reason why I’m hanging around here: I had to admit to myself that by natural means (i.e. practicing) I will never reach the level of perfection I would actually like. So a Plan B developed: I want to build, as part of a DIY project, a kind of “Vorsetzer” that will get from my piano the tunes I’ll never be able to produce myself due to lack of talent. The mechanical part hasn’t progressed very far yet, but I’ve already written quite a bit of software—mainly because that’s simply the area I’m more familiar with.

The current state has advanced far enough that I’m now looking for collaborators for this project. You can’t yet make piano keys press down, but at least an e-piano or keyboard can be controlled via the MIDI interface. Please don’t expect a second Synthesia or anything of that scale! You’ll find more information on the "Depinus" project page at Github. Anyone interested in contributing to this open-source project, or simply finding bugs as a beta tester or making suggestions for improvements, is very welcome!

See you soon,
Norbert

Hi, welcome to the forum.

I'm assuming that this statement is referring to your project as otherwise, it would not be correct. I used to own a 1995 Yamaha U3 Disklavier piano with a built-in control unit, when I lived in Scotland. It always amazed visitors when they saw the piano playing by itself with moving keys. I also used MIDI to also get it to play my Yamaha CVS 10 Organ expander. Technology has come quite a long way since those days.

Good luck with your project.

The video above is interesting, even though I’m pursuing a different approach: My piano should not be altered, but instead played automatically via the keys (using MIDI). How this should be achieved (electromagnetically, pneumatically, hydraulically, or otherwise) is still the big challenge. The actuators should be lightweight, inexpensive (because of the factor 88), and ideally so space-saving that one could even play four hands with oneself. :)

Admittedly, I still have no idea how that could work.

I did an online search to find out what a “Vorsetzer” is and came across this very interesting video. It's amazing that this particular type of player piano 'adapter' was built in 1924.

Exactly, that’s the idea behind it!

And with today’s technology, it should actually be possible to realize it much more space-efficiently than back then. There are original recordings on such paper rolls by Gustav Mahler, Claude Debussy, Scott Joplin, and many others, long before the gramophone and the tape recorder were invented.
