Ultimately, this is a toy. It has limited capabilities as an instrument and that's not necessarily a horrible thing (I like to think of it as a minimized digital handpan). The interface is not really immediately intuitive, so it takes some time to get used to it before you can actually jolt down any ideas and you are ultimately better of using a smaller keyboard if you have basic abilities.
Furthermore, the sound library is not really that impressive and last I used the instrument, it didn't actually allow you to export any of your recordings outside of the supplied software.
I also tried using this as an MPE controller for MPE enabled software and the results weren't that impressive either, although I can see some limited use with careful planning I suppose.
Perhaps this would be a fun instrument for kids to develop an understanding of loops, basic music recording and song structure and generally spark interest in playing actual instruments.
