I use a doepfer A-190-4 USB/MIDI to CV module to connect to my PC and record directly into Ableton DAW. Another option is to get a small tabletop MIDI to CV device like the CV.OCD that is small and portable without having to use precious rack space. I plan to get one to use with my Elektron Octatrack now that I have two 6U modular systems and I don't want to have to always use the one in my first system. I also have an external mixer that sometimes I use.
