But those are just 5080 formatted versions of the original LCDP series for Roland’s S samplers.
edit: I owned an R8 w/ Electronic card a while ago. A friend with an S 760 had (what sounded to me like) sounds with an identical sound signature. He’s the one who told me that Roland used that library in their Romplers & Drummachines. But the R8 might indeed be a bit early for that…
edit 2: turned on my 4000 and looked through my LCDP DRM folder. There are some “KIK R8” files. That probably establishes the chronological order
