Amazing value for money. If you're in the market for some 80's/90's digital cheese, the waveforms here provide. The filter and chorus also sound great. The unusual architecture and poor controls make it unsuitable as a first synth IMO, but for more experienced users it's pretty much a no-brainer.
Between four single-cycle waveform oscillators per voice, a "vector" mixing approach with a dedicated mix envelope, and a paraphonic filter, you'll probably find at least something new and interesting to explore here. And exploring is what you'll be doing since the factory presets are mostly crap and don't do a good job of representing the synth's capabilites.
It's the rare toy synth that isn't just a worse version of something else thats readily available, while also being very usable sound-wise. It gives most other synths in its market segment the run around before you even consider the fact that it's half the price.
The only real complaint I have is the buggy firmware (as of v 1.12). If you have to cut costs, then this is probably the place to do it since it can be fixed afterwards, but its still annoying to have features work in a weird way or not at all. Some usability issues arise from the small form factor and mediocre component quality, but that kind of comes with the territory. The keyboard and sequencer in particular are pretty much unusable, so you'll need some kind of external controller.
Great sound, fun to program, costs pennies, bottom line is just get one if you're into synthesizers.
