i see there's a new version of heliox.. this "review" (acknowledgement and endorsement) concerns the initial release.
makes my top handful of synths list.. not general purpose but utterly unique and extremely applicable for select timbres. the shifting harmonics make heliox an excellent source for signal chains producing complex ambiences, even emulative environments can be created if one is selective in processing.
the original release was pragmatic and appropriate for my applications. people who prefer self contained instruments with on-board effects may balk at the utilitarian form.
