PSRUTI is originally a software for adapting MIDIfiles for YAMAHA devices.
You can download this software here.
On the user interface you can find the function Akkrode berechnen (Calculating chords). Here please select a channel that seems to be suitable (e.g guitars, strings etc.). It is important that this track provides you with the chords which will appear after the selection.
Please confirm the selection with OK.
The software now writes the chords within the MIDIfile.
ATTENTION: If you don’t own a YAMAHA device which is able to display chords, DO NOT save this file! Otherwise you can save the edited MIDIfile with “Save as…” to avoid changing the original file.
You will receive a text file that includes the song text as well as harmonies.
The software asks you to save this file. After selecting “Save” the file will open automatically.
A fast and easy way creating harmonies and lead sheets.
The file can additionally be edited with the help of a word processing program. But usually the created text file is enough.
