How did I do it?

Here is a simple audio clip. One instrument, one Moogerfooger, no FX. Would you like to fill in the details?

You ran your synth through a MIDI Murf with a custom pattern.

Nice try, but I’m afraid you’re 0 for 2. No synth or other digital instrument – analog instruments only – and the Moogerfooger I used was not a MuRF.

Uh, my Voyager is a synth and it isn’t digital! My Modular synth is pure analog, also.

You’re quite right. That’s why I said “no synth [i.e. neither an analog nor digital synth] or other digital instrument [i.e. even if not a synth].”

definitely strings… Not sure if it’s bass or guitar yet - or something similar like a stick bass…

Stuck between ring mod and freq box… gonna go with this though:

bass thru ring mod.

Id say 100 percent its a Bass guitar, the other sounds like a ringmod.

You’re very close to right – the instrument I used isn’t exactly a bass guitar.
