So i had this idea that it would be nice to not only have cv inputs which protect ae modular from overvoltage (cut off everything above 5v) but to also have the option to scale down the input cv, so that you can use the full range.
So i looked at the cv inputs from the master module and made some additions:
Seems to work, at least in LT Spice.
But i am wondering now about two things:
1) Is this a valid / usefull design at all?
2) If you want to use the input for pitch cv then you would disable the scaling by turning the pot to the left, so that the resistance between r1 and the buffer is zero. But the pot is still in the circuit. Would that add an error to pitch cv or doesn't it matter? (maybe one could just add a switch then)
Regarding the input wiring, is there a reason to have the signal connected to the ring ('right') of the jack socket? Surely connecting to tip ('left') is more usual? (unless I'm missing something, of course)
still haven't tried it yet because there was other stuff in the way (new job, rearranging the man-cave, building the lego millenium falcon,...) but i finally ordered the missing parts today, so in the next days i will be able to figure out if it works
