First off- I have no affiliation with cymatic audio whatsoever and what i present here has no guarantee, support and is used at your own risk.
However, i have made this out of self-necessity and want to share it with the community.
I have made a simple playlist editor which allows you to import a playlist and edit the songs and order of songs and then create a new playlist from that.
There are limitations, mainly you can not choose the playback time (ie timed/pause/continuous) and all file/folders are ‘multitrack files’ that must be in the ‘Recording’ directory on your USB storage device. Click here for the editor
PS- i only have and use an LP-16 unit so i have no idea if this applies to other devices!
A useful way to use this (as i do) would be to make one playlist of ALL of your tracks/songs from which you can then create your own custom playlists.
If cymatic have any objections to this i apologise and you may remove.
