Play all channels+voices in all open scores in succession

With this plugin, you can play all channels (or voices, see below) of all parts in all open scores in order to create practice movies for your choir-members. The video's can be created by using this plugin for playback, record the screen simultaniously, and split the resulting video in clips for each choir-voice. Because of the option to use channels, and thus play more channels per bar, this plugin is not tested in musescore 4.X.
Limitation: When no channels are defined in a bar, only one voice (=voice 1) can be used in that bar.
Each seperate channel/voice will be accentuated using volume and color, while the other channels are present , but in the background.
