Oh woops, I misunderstood. On that end, yes, you’d probably want to use a DI, though, again, not entirely necessary, especially if you’re sending synth / line level signals into the pedal. If you’re sending hi-Z (guitar) into the pedals, then have a look around the site in the link I sent above. They also do passive DI box kits. Alternatively, there are many other DI’s out there. Pick one that fits your budget.
