Here's some of it:
It sounds uncannily like a real violin, with highly realistic legato, vibrato, portamento, glissando, and trills.
Seamless morphing between four dynamic layers enables smooth-as-silk dynamic transitions.
The controller options allow very expressive and emotive violin performances.
Very good value for money.
The tremolo simulation is not convincing.
There are no long glissando, col legno, or artificial harmonics samples.
If you're working with a modest budget and need a solo violin to add to an orchestral arrangement or to play on its own, Stradivari is the perfect solution. Although not a good bet for one-fingered programmers, it's a keyboard player's dream — it feels and sounds like a real instrument, and its expressive powers are second to none.
And this is the conclusion:
As you would rightly expect from a priceless, 300-year-old instrument, the Strad violin (played by Pauline Kim) has a rich, vibrant mature tone with plenty of depth and body. The bowing is smooth, assured, and free of inconsistencies right across the G2 to E6 range, resulting in a musically satisfying set of samples. When allied to Stradivari's technical innovations and advanced programming techniques, the raw sounds are transformed into a sophisticated and intelligent instrument which somehow manages to be more than the sum of its parts.
Forget all the technical stuff — the most important fact about the Stradivari violin is that it's enormous fun to play, a salutary reminder of why we all got started in the music business in the first place! As ever, a little bit of keyboard technique helps, but though it can make you sound like a virtuoso, you don't have to study for years to play it. With a little practise, your fiddling will soon rival that of the Enron directors, and unlike Nicolo Paganini (the great 19th-century violinist whose phenomenal technique gave rise to rumours of diabolical assistance), you won't have to sell your soul to the devil to cover the cost of this expressive instrument.
