Sound Junction is for those thinking of taking up an instrument. Each topic is discussed in detail that suggests its intention is to educate. There are articles and photos as well as the history of musical instruments. Tips on how to play instruments in some cases are by video clips.
In the main menu, if you click on “Composer” it contains a simple piece of music editing software. Pre recorded samples can be dragged and dropped onto a time to eventually build to make a finished track.
My technical notes over the time.
