A great little modular synthesizer with a lot of useful features. It allows for all conventional synthesis methods (Subtractive, Additive, FM, AM, Wave Shaping) and specials like Modal and Karplus-Strong Synthesis. Wave-table and Wave-Cycle-Editing is planned, as well as Sampling Synthesis with modulation of playback speed and direction (for scratching, phase distortion and granulation features).

Pros: -extremely easy to use, -great sound

Cons: -too less waveforms included (if you ask me), but with the future sampling feature you should be able to use your own

What I personally would prefer are synthesis methods like:

Pulse Train Synthesis, VOSIM, LPC, Window Function Synthesis, Hard Sync Modulation, Ring Modulation, Bit reduction/Re-sampling/Sample-Hold and Wave Terrain Synthesis (whereas this last feature would be quite hard to implement, I think)

For that price - absolutely convincing synthesizer!
