so far, i didn't have any problems interfacing my
serge to any of the other modulars i have.
indeed, serge working voltages range is +/-5volts, so
it works fine with the doepfer, but as you would
expect, in some instances, the output voltage of the
doepfer modules will be partially unused from the
serge cv inputs (due to the difference of range).
but, i do not think that this causes any problem.
just use cv attenuators...
if you do not use attenuators, you will sometimes just
have 'peaking' behaviour of the doepfer cv's when
controling serge cv functions.
anyway, the doepfer cv's are mostly up to 8 volts,
IIRC, so there is not a big difference...
regarding syncing triggers/gates and such they seem to
work fine...

although i still have to work with them in combi more
months to really find out all aspects of their
cross-compatibility.

bottom line is: i think they'll work fine together.

you just need LOTS of banana's to minijack converter
panels (custom made for you).

the reason is that you DO HAVE TO HAVE common ground
between the serge and other (mini)jack modulars.

minijack cables 'carry the ground with them' but
banana's do not.

so, you have to use a converter panel that is grounded
to the serge psu when you convert from banana's to
minijacks and vice-versa, to connect the serge to
other jack modulars.
this banana to minijack panel can be easily made by a
tech for you. (and you can then mount it into your
euro rack, but you have to connect the ground pin of
the converter's minijacks to the ground of the euro
rack internally) and the serge psu must be grounded to
the eurorack psu.
i hope i'm right in all these, i'm no tech...

best regards,
Bakis.
