Linear to S Curve conversion

[Acetronics2]

Hi, Darrel

Reading your kind post ... I just remember placing a resistor from the hot side of the pot to the cursor, and another, the same value, from the cursor to the cold side of the pot give a nice exponential shape to the "pot " response.

so, using a twin pot instead of my two stupid resistors might give a trimmable response ( care to the minimum value !!! )

Was a pleasure to help you

Well, it seems that the stroke does not matter anymore, the difference is not significant.

Case closed and I'd like to thank you all for helping
