Alesis Andromeda A6

I guess I have to put my money where my mouth is now,  since you've went 
through all this trouble here! (thanks for posting the info, by the way)   ; >
 I've got a nice A/D, will post some recordings when I get a sec and will generally try to 
debunk myself in the meanwhile.

I believe I can hear the distinction double-blind with no problem;  I kind of know what to 
listen for.    I've just had a much easier time programming once I started using the Auxes.  
I find it harder to get an open sound out of the main outs, sounds like there's some kind 
of coloration & a sheen there, it gets into the sound.


I don't think volume is the main factor (although we never do-!) -  my levels were 
changing all the time in any event, sometimes the main outs were set up to be louder, 
same results.   I use the same cables & board inputs.  

I'll check it out again over the weekend, will be rehearsing and gigging using the A6 as a 
bass synth.

One last thing to consider is that we hear a lot of nice stuff that doesn't show up at 48Khz.

peace
