Confirmed sources:
Roland R-8 (1989) - Used for percussion instruments
Korg M1 (1988) - Multiple melodic instruments (funnily enough, Samurai Pizza Cats also uses it)
Roland U-20 / U-220 (1989) - Has been the source for most Roland Sound Canvasses and 90s Roland sounds. Honky Tonks and Shamisens sound like it.
To be found:
FM Slap Bass source - Very common in the 1980s, and probably in multiple synthesizers. It's something you hear in the intro, outro, next episode and trivia songs. It's possibly from a Yamaha, but I don't know the specifics.
Strings Ensemble source - I have no idea.
How can you help find?
If you hear something familiar, and know its branding, it'd already take us on the right track!
Since a lot of sounds these companies use are shared, even in later modules or synthesizers.
