The process of installing the Native Instruments Pro-52 virtual synth was pain free and only took a matter of minutes.  I've also never heard on anyone having any problems getting this to work, so I'm under the impression that it is a pretty stable piece of software.  The interface of the software is really easy to follow as all of the sections are easily located and are labeled clearly.  It has all of the pieces of the puzzle that you would expect from a virtual synth like sections for two oscillators, a mixer, an amplifier, a filter, an LFO, delay, and a variety of other effects and parameters.  While it may take a while to get through everything and really learn everything possible with this software, it is definitely easy enough to operate that you don't need a manual.

SUITABILITY/PERFORMANCE

I've never had a problem running the Native Instruments Pro-52 either as a stand alone or routed into a sequencer like Logic or Pro Tools.  I run the virtual instrument on a Mac Book Pro that has a 2.2 Ghz Intel Core 2 Duo processor and 4 GB of RAM.  This does the job fine as I am able to run software without any issues, but only one at a time.  I don't see a reason that you would need to run more than one of these at a time and would suggest only using one at a time unless you have a superior system. 


OVERALL OPINION

While they have since put out the Pro-53, the Native Instruments Pro-52 is still a great virtual instrument.  The presets are awesome and you can pretty much get an endless amount of sounds beyond this because of the vast array of parameters and effects that are available to you.  The price is great as it is less than $100 USD and for this reason is a great buy for anyone looking to add or start their virtual synth collection.  Definitely try out the Pro-52 (or 53) as it is a great virtual synth.
