Nothing — no comparative function or capability is stated in any source.
What it does badly
It offers no verifiable functionality to assess. There is no evidence of what it does at all.
What people made with it
No recordings, artists, genres or works made with it are mentioned.
Who should use it, and who should not
Only researchers who work exclusively with gaps in the historical record should consider it. No player, producer or sound designer can use it without documentation.
Is it worth your time
It is not worth your time unless you are researching unrecorded hardware with no functional documentation.
