I bought this Synth 2 Weeks ago and was impressed about his Sound.
Dune has a crystal clear transparent sound.
A Big Plus is the Arpeggiator. Very easy to use but extremly powefull. The Factory Arpeggio Presets are amazing. The only thing I miss is to save my own created Arp Presets. Maybe it will come soon as a Update.
I like the Interface. There are not to much Faders, Knops or Funktions to overhelm me. It's well balanced and looks cool.
Im using Dune with Logic Pro 9.1.3 and it works Perfect.
In all, Dune is worth every Penny and Im using it in most of my Productions.
