I only just learned of this synth, but supposedly with it's new release along with a new software version, it is dropping in price by $200.
Originally $499
Now $299
I really like the interface of this! Looks like so much fun to play with and without a keyboard.
The 100dB sweep filter @ 1:20 (video below) is pretty intense indeed
Should be fun to sequence with Reason. Also, I wonder if this software could be made into a RE...
