This might help but not sure.
My current solution is to run the Eurorack outputs through my audio interface’s preamps and capture the audio interface’s main outs which output very cleanly and the DACs have a huge range. This makes live sampling essentially impossible but it’s a good studio setup for experimentation. I’m ordering my first set of modules next week and I have a quad attenuator in there. Even my guitar seems to run hot in the Octatrack when I use a preamp pedal and reduce the gain/increase volume, really don’t know how direct modular outputs will fare in there without having to lower the volume too much, increase the gain and distort the sounds.
Let me know how it goes.
