Connecting Arduino to Yamaha Clavinova CLP-150

[Genkaz]

A very helpful individual in the last piano related thread suggested to utilize an Adruino platform to reanimate a piano with the utilization of this project GitHub

Unfortunately I have very little experience with working with electronics and I am not sure how practical or feasible it would be to do so.

The main issues currently consist of: Being uncertain of the right voltages in order to not fry anything or whether I would require any resistors or additional electrical components.

The fact that the project currently only supports 61 keys while the piano has 88, potentially requiring something that I learned about today known as "multiplexing",
which would also require rewriting the code in order to make that work I think.

The fact that the pin connectors that the piano has cannot be plugged directly into the Arduino without a converter that changes the piano's tiny pin connector format to the much large arduino one.

Lastly I wanted to mention that the piano has excellent speakers that would be a shame to let go to waste, so making those function could be nice also.

Please let me know if this idea is retarded or if it's a good one and whether it is a reasonable project or not. Any assistance with this would be appreciated.
