Convert Voltage Lin->exp Or Exp->lin, Hands in the electronics Options

[overtheclouds]

hi

i am currently mounting the electronics of a MS20 and a SEM in one rack. problem is that they use different
control voltages. korg exponential and SEM linear. and i would love them to work together as one.

do any of you know simple circuits that reliably convert either linear to EXP or EXP to LIN? whatever is easier
as my midiinterface (PAIA midi2CV8) can do both.

thank you in advance
