I've ordered the Beat Garden rom for the XL7.  I'm looking to buy the 
Techno Synth and the Protozoa.  Is the Techno Synth an essential buy 
for techno/trance as I've read that some XL7 ownwers don't rate it 
that much?  

I'd like to have a good bread and butter set of sounds for music 
other than dance.  That's why I'm looking at the Protozoa but I 
couldn't find any demo's of it.  Is it worth buying?  I've got a few 
GM sound sets on my computer so I want more than just another GM 
sound set.  Does the Protozoa have good sound quality and variety?

Cheers!
