It is excellent. It covers all the basic waveforms (sine, square, saw, etc.). It has an internal VCA and envelope generator (and low-pass gate emulator) that make it very immediate to patch. It has more advanced modes, such as a 2-operator FM, wavetable oscillator, harmonic oscillator, and various percussion and noise sounds. It is great for experimenting with all these different oscillators and modulations. No brainer. Go for it.
