This was his last nearly all analog classical album and last 20th century quad release (1979).
He had gotten a CS-80 though Vangelis had his since Spiral in 1977. Tomita's synth was modified with 2 jacks per voice, 2 groups of 8, but it's unclear what the modification was for. Perhaps to sequence, perhaps to use as a master controller, perhaps multiple outs to pan in stereo?
You can read a wedding dedication to his daughter and new husband in the grass on the cover, "To Rie and Masaharu", (his name is kind of difficult to decipher)
