All OM generators provide a balanced (neutral) frequency response; Please note the following; the Super-OM generators also give exactly the same balanced neutral response as usual, but consistently "one (or more precisely half) pitch higher" (consequently a tip for all those whose "system orientation" (in the composition) is a bit too bass-heavy ...).
