Don't get me wrong Dune 3 is a great synthesizer, but it's simply a different synth the the original Dune.
There's something very organic sounding about Dune and I love the OSC FM feature. I simply cannot recreate the patches I did in Dune in Dune3, they just sound completely different.
I really hope you could bring back Dune Classic at a cheaper price point (like Hydra) and update it to VST3/M1 so it can live a long happy live along the other synths.
