the only module that can do both attenuation and offset per channel, that I know of, is the happy nerding 3*MIA - but you'd need 3 if you want a channel per ochd output

Ordered and received. The 3MIA works super next to OCHD. I may get a second one since I have 2 OCHD modules. 3MIA will be very useful in general. Another thing I have that does offsets is Befaco A*B+C.
