Well, obviously I'm biased, but ... I reckon the Biolabs sounds are pretty different to the other stuff. However, I'd advise you to grab the 60 or so presets you can get for free (theres the Biolabs 1-3 demo set + extra TC patches, plus the Biolabs 4-6 demo set). Try playing with those and if you like em and they inspire you, consider getting the others, if not, get something else.I'm looking at Albino 3, Blue, Rapture, maybe Vanguard, as well as the Biolabs Absynth Research Sounds vol. 1-6. Maybe some MIDI drum beats from Groove Monkee. I really have no idea. Do any of those fill some void in my current library? Maybe there is something else out there that I haven't yet considered?
You could check out CamelSpace and CamelPhat and see if you like them. I find they're both pretty handy for inspiring me to write stuff and injecting a bit more fun into music making. Even if you don't get them, you might want to consider grabbing the newly released CamelCrusher multi effect, which is free.With that pile of instruments I'd get some sweet FX.. I'm getting the camel FX myself.
