I didn't have any problems installing the MOTU MachFive virtual sampler.  The whole process only took a few minutes and was virtually pain free.  The interface of the software however is another issues.  While I wouldn't say that it is convoluted, there is definitely a lot of different sections and features that the MOTU MachFive has to offer and therefore there is a lot going on within the interface.  However, after carefully perusing the software I found that everything was put together well and easily located after playing around with it for a bit.  The manual for the software breaks down everything you would need to know about the software and can be helpful if you have it.


SUITABILITY/PERFORMANCE

The MOTU MachFive will definitely take up a good amount of processing power and isn't the type of software that you can run a lot of at a time because of this.  I am currently running the software on a Mac Book Pro that has a 2.2 Ghz Intel Core 2 Duo processor and 4 GB of RAM and I am able to run software pretty well.  As long as you have an adequate system to run your sequencer on, I don't see why you wouldn't be able to run this as well, just don't expect it to run all that fast if you don't have a good system.


OVERALL OPINION

All in all, the MOTU MachFive is a very powerful piece of software.  The basic functions of the software are easy to use and to understand and the rest of the software allows you to do some pretty in depth processing, effects, and other sorts of sound manipulation.  If you are looking to get into sampling, using the MOTU MachFive with Digital Performer will give you a powerful system.  The price of this software isn't too bad, but isn't the cheapest, however considering all the things that you can do with this, I would say it is worth the price for those who will use it.  Definitely a piece of software that is worth looking into.
