Thread: set up with motu 828x
The Volta + dc-coupled external MOTU interface method is a bit of a kludge; there's a better way to go within Eurorack itself. Have a look at Expert Sleepers' ES-8 USB interface and ESX-8CVmkii expanders, as well as ES's Silent Way software instead. Cross-platformable (Volta is Mac-only, last time I checked), much more compact, plus you have four return CVs back to the computer to use either for recording or tracking CV/gate activity, or both. Voltages range up to +10 as well, giving you a full CV range instead of the MOTU's restriction.
