Selecting the "Piano Grand" preset, the comments state: "German grand piano, that recreates an intimate piano sound. Change the Reverb Dry/Wet to get the feeling of having the piano in a room."
Now, selecting the "Piano Upright" or "Stage 73 EP" etc, the comments remain and aren't cleared. I don't think a Stage 73 EP is anything close to a German grand piano.
Actually, selecting an "Arp & Lead" shows it's comments but, selecting any of the Piano & Keys always shows a German grand piano.
Any preset in "Song 3 - Analog dreams" returns the same comments for the CS80 Pad, even the Modular Seq preset. The same occurs for Song 4 selections.
