The graphics in eJay Clubworld are better than they need to be. There is a color organ/light organ mode (called 'Video Mode in' eJay Clubworld), that generates some nice visuals to go along with your music. This is a nice touch. Some of the visual effects in eJay Clubworld, however, such as the way that selected tracks 'spin' onto the sequencing area, are borderline obtrusive. I would rather an instant reaction than a pretty spinning effect that takes a little bit of time. The 'water-like' distortion effects in the background of the sequencing area is a nice touch and doesn't appear to hinder any of the other processes.
The sound in eJay Clubworld is what it's all about, and thankfully eJay Clubworld has got that covered. There are many, many different sounds samples to choose from (all of them royalty-free, by the way...) and many of them are variations on themes. This allows you to have subtle differences in different sections of your musical compositions, allowing your score to sound more 'human' and less cookie-cutter. This is especially good for the clubs that have vocal samples in them, such as the Brooklyn club with its rap parts and the ZOUK club with its robotic voices. In addition to the samples provided, it is also possible to use the editing tools to select smaller parts of the existing samples, essentially 'sampling' from these samples. Using this technique, you can create 'sample and scratch type effects (in any club, not just Brooklyn). I was a little upset that the samples provided didn't include complete break-outs of larger samples ('Feel the Energy' is a sample, 'Feel' and 'Energy' are samples - but 'the' is not provided), but using the above mentioned sampling technique, it is sometimes possible to create your own 'the' by cutting it out of the larger sample.
So, what of the quality of the final resultant songs? They're pretty good. In fact, I can imagine a DJ actually playing a club using eJay Clubworld in their setup. Take two PS2s with eJay Clubworld on them and a video wall or a couple of monitors around a club and throw in a video selector switch and you're ready to roll. A DJ could actually work on creations on one PS2 while playing off of his jukebox on the other PS2... then use the external video/audio selector to mix between the PS2s.
