I'm making an amplifier with a VCA and I want to create a pot control that responds like a normal log pot. Obviously when you control the volume with a linear pot into the control port of a VCA, it never goes to 0 without altering how steeply the volume cuts off as you turn the pot.
I read elsewhere that a log pot is actually two tapers, a log taper and a linear taper which goes to 0 at the end of its range. My question is at what point of the taper does the linear taper start? Its a little difficult to measure this reliably with a physical pot
additionally, does anyone know a schematic for VCA control which does this? I can't have been the first..
