Dr. Who wrote: So what was used for the filter sweeps around 4:57 in Oxygen I? At first I thought it was a chord but listening to it again it doens't really sound like a chord just a multi-oscillator synth with a nice filter sweep. Hmmmm still curious about this one???
That's just a detuned saw patch that you can do on pretty much all old analogs!
I've done it on my MiniMoog and ARP2600!
It's the kind of brassy sound that doesn't immediately say: aha I'm from an ARP or I'm from a Mini! It can be done on many synths! Maybe he used an ARP, maybe the KORG or even
the MOOG 55!
My question really is, regarding that track and (Equinoxe 4 for that matter), is how the hell he created that enormous bass drone?
Without faith nothing is possible. With it, nothing is impossible.
