I'm not sure I liked the tone (or full step) of some of the posts.. I think they were a bit sharp (by about 24.7Hz).
 
And some of these puns are starting to fall flat (by 5Hz).
 

To the OP....there is a transpose function. Never used that myself. I always just play my Synths in whatever key the song is in. A - G# whatever....Other than that I'd try to detune the synth in question to the other instruments. I personally just play in the key of the song, it's so much easier! FOR INSTANCE... I did a demo for some kids recently and they played in Drop C#. Some real heavy sounding stuff. I just played the pads and whatever else they wanted in that key. I never detuned anything.

pppfffft. 
 
I have my own tunings.....so there...hhmmmppphh

@DaddyV - what the OP is asking is not to transpose, but to "slightly flatten" his reference tuning, so that his material is 8Hz below "standard", regardless of what key it is in.  There has been a lot of hocus pocus about this recently, with people believing it "sounds better".
 
@OP - Perhaps try recording an example in both A=440 and A=432, and listening to them in several different environments.  As spacey pointed out, you could use zeta and detune it to A=432.  See if you can hear an improvement.
 
Perhaps post your tracks, and other people can comment.

I don't mean to stir the stew on this thread, but I came upon this interesting if somewhat off-the-wall article related to the whole 440vs432 base for tuning.  Before anyone yells at me, I still tune to 440 and do not personally endorse the following information which is presented for your information.  LOL.

I'm glad you bumped it. Otherwise I would have missed this:
 
"you sound like a novice cook trying to argue with a master BBQ chef that Boston Pork Butt is really actually meat from the hiney and not the shoulder because it clearly says "butt." The chef keeps trying to tell you it is from the shoulder but, oh well."
 
Priceless.
 
As for the idea that any particular tuning is more natural/spiritual/magical than the next, I feel compelled to point out that any tuning based on measuring frequencies in Hz (i.e. cycles per second) is highly unlikely to have any special "harmony" with "the universe" given that the duration of a second is a totally arbitrary, man-made value. There's nothing "natural" about it. No harmonic phenomenon in nature fits nicely into our arbitrarily defined frequency scale except insofar as the second has been arbitrarily defined (since 1967) to be:
 
"the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium 133 atom."
 
 
 
 
 

Chuck, you have my compassion.

Anyone experiencing psycho social agitation caused by music tuned to 440 HZ should run directly away. At, oh say, a speed of about 20 & 1/2 feet per second. In dry air at about 68 deg F, that is.
