macolganWell..... I suppose I could knock up a galvanometer circuit, set as a constant current potentionmeter to maintain balance ... not sure just how ugly it would be though, hanging from your neck ! :|
sm2nShocking! I can't believe you want a digital solution when you could invent a perfect electronic solution yourself. I'd buy one of the Macolgan Volume Regulators :-)
macolganHa ha Simon... doubt I'd be "inventing" something that wasn't already commonplace !
Of course, what we're really talking about here is some form of " digital software controlled volume attenuation " as in a " dithered " set, but - that will allow/accept fixed and maintained presets :)
