Probably because I'm more used to the GUI of Dune 1. I love Synapse Audio Dune 1 VST!! Hey, Just ranting, but I still love Dune 1 VST too much. Described as a ‘true unison monster’, Synapse Dune VST has a maximum reserve of 8,320 oscillators at full polyphony – meaning it is unlikely to ever run out.
However, the ProTools offer is only available to the 64-bit offering. Synapse Dune is available as a VST/AU/AAX plugin for Windows, with the VST coming in both 32 and 64-bit versions.
