Yep, I despise Behringer. ;) However, functionality definitely works when needed. My take on that would be to wait until B. comes out with the Pro-One clone, though, as I think the original was a superior monosynth overall when compared to the original Minimoog. The modulation routing capabilities alone are worth the wait, plus in the case of B.'s reintroduction of the CEM chips (even with their janky semi-piracy of the architecture), well, that was a move that I feel was 100% warranted. Now if someone would step up to the plate and get the SSM silicon back on the street, I'd be similarly unopposed.
Another way to get those bell timbres would be a ring modulator, of course. Yes, this requires two VCOs to work, but you really should have two anyway for detuning, working waveforms against each other (swept pulse against square, for example...quite nice) and the like. And the ring mod offers its own set of extra functions, such as being useful as a spare VCA of sorts, modulating audio with LFOs to create 'chopped-up' sounds, mangling incoming audio, and so on. It's very much another of those "boring" modules that gets overlooked...when that shouldn't be the case, as ring mods are part of the "bread and butter" of electronic music devices. Plus, they're small and cheap (usually).
