I bought the FL/Image Line version of DX10 after being so happy with SimSynth Live and Wasp. I have mixed opinions of this synth. It is wonderful for learning and exploring FM programming. For anyone that wants to learn, this is a great synth to start. It sounds good and covers the basics. Sadly, this synth is overshadowed by some major FM based products. I tend to forget I have it. That is a mistake. Not every instrument in a song needs loads of effects, filters, and complex eg’s. When you need a simple FM part DX10 can do the job reliably and with efficient CPU usage. In my opinion, it is worth the price just as a tool for learning the basics of programming FM. As with SimSynth Live and Wasp, you get FL, DXi and VSTi versions with the purchase.
