Hi Oldden,
As far as I know, there is no such dedicated program for creating / editing Yamaha Genos Playlist files. I do not expect anyone to write such program as well since Microsoft Word and Microsoft Excel can already handle these files.
The Genos Playlist is a file with the Playlist name, and a file extension of .tsv. The .tsv file is actually a text file, the format of which is equivalent to .csv (comma-separated separated) that programs like Microsoft Word or Excel can open, edit and save. Since Genos is running a Linux OS, each line of the .tsv file does not have an extra carriage return like Windows text files and so the file looks like a big long line instead of separate lines.
So, yes, you can simply use Microsoft Word (Word can automatically converts Linux/Unix text files into Windows text format), or Microsoft Excel to open and modify an existing Genos Playlist file if you first modify the .tsv file to .csv file, make your modifications, then save it as .csv file, then exit from Word / Excel, and rename the .csv file to .tsv file.
As for the creation of a new .tsv file, you can always copy one of your existing .tsv file and rename it as .csv, open the .csv file using Microsoft Word or Excel, leave the first 2 lines untouched:
TITLE FILEPATH REGIST OPENVIEWER
[About This Playlist] D:/REGIST/About This Playlist.rgt 0 TEXT
Replace the following lines with your own references of Song name, Drive path of registration etc (I: means USB1):
1492: Conquest Of Paradise I:/PlaylistForGenos/Movie&Show/1492 Conquest Of Paradise.rgt 0 OFF
1999 I:/PlaylistForGenos/RetroPop/1999.rgt 0 OFF
99 Luftballons I:/PlaylistForGenos/RetroPop/99 Luftballons.rgt 0 OFF
A Hard Days Night I:/PlaylistForGenos/Oldies/A Hard Days Night.rgt 0 OFF
. . .
Then save the file, exit from Word / Excel, then rename the .csv file back to .tsv file and copy it to your Genos USB drive.
Thanks,
Paul
