Hi Paul, thanks for the reply. The pre board I am using already has a relay resistor volume control which sits on the output side rather than the more conventional pot then gain stage so I was hoping just to add input switching with ht bypass without the volume control for this project. Is that possible with this setup?
Cheers,

I tried with 60 steps, and the hump moved to step 29-30. This looks like a problem with the middle step.
You could just use it for input switching. Optionally you could strip out all the code that drives the LDRs etc.
Good stuff , any idea how to use say 3 inputs one of which is the ht bypass which connects input to output , totally bypassing the gain stage?
Hi Paul
Yes it working good now with 4 inputs and 2 outputs.But i have little noise at the middle 30-35 of volume i think something happen with the way i pull out the Gnd input -output ,i think must pull out the cables from the same spot of GND.

You could do this but you would need to cut a number of tracks on the input board for the third input so that you could use it instead as a c/o relay at the output.
I managed to write a very fast and compact OLED VxD code using SSD1306 Ascii library. It seems to have even faster refresh rate than LCD.
