The LP sounds quite different to the voyager to me. The filter is voiced differently to the voyagers for a start, ie its response sounds slightly different. It opens up a little more than the voyagers in the top end so it sounds a bit brighter. The overload control adds a dimension that the voyager just cant do;its def got a more aggressive sound even with the overload at zero.
Yes they both have the moog character and feel but i see the LP as the perfect immediate raw, portable and cheeky moog that works in pretty much every musical situation and the voyager more as a studio/sound design very deep instrument that can be used live of course but is a little more complex to get to grips with in terms of its interface.
