When it comes to music production softwares, there are so many commercial tutorials available from such companies as Groove3, Lynda.
In fact, I would argue that there are TOO MANY of them. For example, I cannot count how many times we encounter tutorials about DAWs like Ableton Live.
Meanwhile, apart from random videos on YouTube, it seems there are not any proper long tutorials for major arranger keyboard models.
Is it because there is no commercial demand for these tutorials, or is there something missing in the brands' mindset?
