The 'hacker way' to me was to use my programming skills to write some software that helps me to achieve my goals. The project is steadily picking up steam and now has a small but quite dedicated following. It has helped me to build up a repertoire of pieces that I can play well enough to execute them fault less which leaves me free to concentrate on how I want to play them, good enough that the people I live with will ask me to play a certain piece because they enjoy it.

The next step is to outfit my ancient Yamaha G3 (1966), that I bought relatively cheaply with a sensor bar so the software can be used on the acoustic piano as well rather than just on the digital one. I love the sound of the acoustic.

The software will be further expanded over the next year, we have a very long list of things we want to add and make it do, hopefully without cluttering the user interface by making most of it completely automatic. Some of these features will be groundbreaking, the current iteration is more of a testbed than anything else. If you want to mess around with it or hack on it feel free: https://pianojacq.com/ the code is on gitlab as well.

I actually saw the software and want to use it !

However what is the self-learning path to follow ? What is the pieces to practice ?

Im hoping you have an opinionated idea- it may not be perfect, but for a person like me ..super valuable!

This is why I'm so happy with the Mayron Cole material, I will try to transcribe all of it to midi files so it can be used with the software. It turns a 'neat little toy' into a complete computer assisted piano course.

For the moment though your best bet is to simply download a bunch of midi files and pick some that you would like to learn.
