It's a nice sampled sound, but you can tell by listening to it that the sound engine is dead basic, probably limited to ADSR and very little else beyond that.

You can tell easily just by listening to how only the volume of the sounds changes. There is no tonal difference between a soft note and a loud not, no expression and not even the attack changes.

So, great sample, but the sound engine is bloody dead basic and it kills the samples in the process.

Here's what a good sound engine sounds like when dealing with samples. http://www.irishacts.com/misc/violin.mp3
