Hi,

to RECOGNIZE chords you can use a program originally written for Yamaha-PSR- Keyboards.
But works fine for many other purposes ( batch possible, GM-converting e.g. )

It´s called "PSRUTI".

You´ll find it at :

Left side use "PSRUTI" and download it. It works under Win10 without any problems.

It will create a ".txt" file with the chorde ( "export chords function" )
