This is a crystal clear sounding 4 operator FM synth, a baby brother to the classic 6 operator Yamaha DX-7 synth. These FM synths have a distinct sound, which is very different than the typical subtractive or sample-based synth. The DXi implementation sounds great and the UI is great, especially on the iPad. The algorithm/operator editor is cool, swiping through the algorithms and then touching an operator to configure it. But to me the most fantastic part is the ADSR envelope editor, which, on iPad, highlights each stage over time as a note is played...on the one hand, its completely obvious, but Ive seen a lot of synths and never encountered it before. If Mr. Mizuhiki came up with this, he deserves some kind of prize, and hopefully he didnt patent it!
