The Yamaha AN1x Synthesizer mailing list

Hello,

I've recently purchased my first synth, the Yamaha AN1x.  I'm new to 
analog synthesis and VA's so I've been reading many sites.  Several 
sites I've come across mention detuning the VCOs to create a "fatter" 
sound.  

What is a good difference in the pitch setting to create the fatter 
sound without making it out of tune (same goes with the unison detune 
feature)?  Also, what pitch setting will transpose an oscillator one 
octave above/below the other?  Any info about pitch is appreciated :)

TIA,
Forax
