DUNE is simply stunning. The sounds can be very complex, yet there is great simplicity in using it and tweaking parameters.
The MOD matrix is VERY powerful, lots of options available.
I was amazed at how quick and easy this synth is to program.
The CPU usage is very low in my opinion, I have used it on a Pentium D, as well as an intel i7 quad core.
Low bass notes are very defined, you can really get some nice deep basses out of this synth.
It is also very stable, the only reason I gave it a "9" for stability was an anomaly caused when Ableton Live somehow got set to 22kHz sample rate, and DUNE made horrible crackling and distorted sounds. This may have been related to the system I was using, once I corrected the sample rate, all was good.
Now that I think about it, Dune is very stable and I am modifying my score to a 10.
Great Synth! And, at $139, it is a VERY good deal! Buy it, you won't be disappointed.
