In going through my old computer, I found a series of videos of Kevin working on an Arp 2600. Most likely late 2012, from the file names.
Found this in Kevin’s “work” folder:
Open High-Hat decay extension
TR 808 OH decay mod
These are sounds for the Roland Jupiter 8.
I have no idea of the origin of these sounds–if they’re factory sounds or custom ones Kevin made.
How you load them into your JP8 is completely up to you, and you do so at your own risk!
Kevin’s keyboard setup, circa 1980.
Kevin’s gear, circa 1980
And Kevin, during the same time:
