(For Battery 3) Really, I don't think there's anything more to ask for from Battery 3 - the interface is streamlined but comprehensive, and the sample library is brilliant. I'll cover the library first. There are the basics, of course - TR-808 and 909, CR-78 and Linn Drums. There are acoustic kits ranging from heavy rock to pop to jazz, with several of them sampled in extreme detail. There are also a large number of experimental kits, one made entirely from basic waveforms with processing, one made from samples taken inside NI's Berlin headquarters, and many others collecting various unusual sounds. Of course, the question isn't the amount of sounds - there are dozens of programs that offer large sample libraries - but the quality of the sounds there, and when it comes to quality, Battery is hard to beat. The drum sounds are crisp and useable, and it's hard to imagine anyone exhausting the set. Battery will satisfy everyone from the pop musician looking for a quick preset to the experimental producer creating weird, glitchy sounds. The interface is next. Battery is easy to use, despite its complexity - there's a sample browser that lets you load your own samples with ease, as well as a system of cell presets that lets you easily drop in different built-in sounds to create your own kit. Effects, modulation, and the like are all in separate tabs, so that you the GUI isn't cluttered up with controls you aren't concerned with accessing. Battery allows you to create your own sounds or use preset sounds easily, making it a real pleasure to use.
