[A6] Moog Drift

[MelloT at aol.com]

MOog drift is not really "a thing"; some do it ( a lot), some don't. It's nothing you could "copy" as such, just make an approximation of what sounds good to you. 

Remember that some old Moogs drift way too much, causing bad intervals, not just detuning. What you are after here is a nice non-modern, non-locked tuning. Again - just turning off autotune and temptune accomplishes much of this. REAL analog drift!

Alternately, randomizing pitch on each note (as you said - voice random) can do it, as can moving-pitch on every note (LFO, or Random LFO). You could even just use slow LFO's that are modulated by voice or global random. Or subtle Noise sent into the pitch...

There are infinite ways to accomplish this, but no way to get just "Moog drift" as there is nothing exactly defineable there. But you will hear the thickness (also seen as instability, or out of tuneness!) and can use this for many sounds you create. I use it all the time when doing more organic, acoustic instruments (choirs, strings, pipe organ, Mellotron, etc)
