I just completed my first Eurorack module design and build, the “L7”. It’s a 1U 12hp tile to simplify cabling and shift the levels to create an effects loop with the Pisound. The left side of the module takes in two audio signals and combines them into a stereo output; optionally allowing for straight through output or level shifting it down for the Pisound. The right side reverses the process; stereo in, optionally boosts the signal back up to Eurorack levels, and splits the signal out.
I’ve been thinking about making this available as a DIY kit sometime in the future. Anyone interested?
