I often find myself producing similes of classic video game sounds on my vintage analog gear like the Pro-One, Casio CZ-1000, Juno-106, MKS-80, or in this case on the Oberheim OB-8 that I am borrowing. Usually this involves pulse wave oscillators, LFO modulation, or high-speed arpeggiation. Aside from being nostalgic it is a good exercise for learning the synthesizer’s controls. Here’s some Pacman-esque sounds done on the OB-8. I converted it to mono and left it unprocessed to exemplify it’s vintage sound.
