The video seems to be trying to convince me that this is totally targeted at actual musicians. But I guess maybe that's how their target users imagine themselves?
As an actual musician who doesn't have any troubles creating my own melodies and timbres (both generated and 'manually' created), its very obviously not targeted at someone like me.
It seems similar to a Garage Band type of software, aiming to entice people with little audio production experience and give them an interesting sounding snippet they can play back to friends.
For example, the only actual audio editing they displayed was slicing and re-pitching (you can't even choose the time-stretch algorithm), which is conceptually very simple to understand.
There's no ability to actually edit dynamics or do very accurate frequency adjustments that I can see from the demos, so it's basically useless for anything I would want to do.
Is a scrapbooker an artist? If a scrapbooker is an artist because of what collage is, is a MtG card collector picking layouts to arrange their cards in the array of plastic sleeves you can get, an artist?
If the MtG card collector is not an artist does that mean they're bad and need to stop?
If the MtG collector only orders the cards for the joy of making a pleasant composition and does not provide any function like finding the cards faster or keeping them in good shape.
I think they are doing art.
If the main reason is to keep their items clean, as much time as they use doing the composition or how good it looks, they are not artist.
They don't need the same feature list.
