Keep in mind with the Intellijel I/O that you can use 1/4 inch cables of the sound outputs
from the Subharmonicon / Moog32 / DFAM to input directly into your Eurorack on its input side
as 1/8 inch cables, and then out again as a whole with 1/4 inch output cables (or 1/8th if
directed into any of the semimodulars). Do you use an external
mixer unit? I found that helps immensely to bring everything together, and 1/4 cables are the way
to go.

If you ever want to use guitar pedals as an extraneous modulation, it is simple to loop through
those as well.

I love the possibilities with Eurorack!
