simple question on the simple mixer…
as far as I understand, pro-desks use LOG pots to compensate for the progression on the decibel scale and provide a closer to linear control of the signal amplitude.
The Simple Mixer states LIN pots.
Am i misunderstanding, or would it be better with LOG pots?

if you have some log you can use them (maybe better), I have lin on all my diy mixers and it suits me like that
Yeah, I like audio taper better for audio 
Keep track of which is which though-the logarithmic progression works for audio signal level, but not so good for oscillators, envelope generation, and many kinds of attenuation.
Mixers don’t have to be exclusively for audio. In fact you could build one with log pots for audio and one with linear pots for CV.
a stupid question : i don’t know audio taper, is another name the same for Log ?
Yeah, they’re usually marked A for Audio. They’re neither audio (as in human hearing response curves) nor log, but rather piecewise linear, but that’s electronics conventions for you.
Note the V curve, btw – the alps potentiometers I got that graph from use a mostly linear curve for their volume control, not the textbook “log” curve. See here for a few more variants.
yes i know A Log and B Lin but i do not know Taper, thanks !
See e.g. Doepfer A-138:
Module A-138 is a four channel mixer, which can be used with either control voltages or audio signals. /…/
A-138 a: potentiometers with linear response, so especially suitable for control voltage mixing.
A-138 b: potentiometers with logarithmic response, so especially suitable for audio signal mixing.
So, in answer then… It woudl be better with (LOG / A / Taper)… But it’s not a big issue…
But avoid using them elsewhere ( Been there, been stung ).
I have a few LOG sliders that have no use to me generaly so will put them to good use
