[sdiy] ASM1 VCO input question

[Michael Buchstaller]

Hallo Group,

a simple question for the Gurus within us:

A friend has 2 ASM-1 boards, and i am helping him to build it. He has made
a front panel similar to the one made by Chris List, that has several CV inputs
for the exponential CV.

Now, in the schematic i see that there are actually 7 inputs with 100K resistors
as a summing node. The opamp U1-A has enough gain to make this acutally
summing and not mixing.
Now my question: What will i have to do with the unused CV inputs ? Will i have to
tie them go GND (maybe via a switching jack), or can i just leave them open ?
I am under the impression that the 1V/oct trimming will be affected if the number of used
input changes - or am i missing something ?

TIA !
