Is the prophecy any good to use for trance/goa style music???

Yes,
it's fantastic for anything that's
trippy and trancy and for stuff meant to
mess with people's heads (and feet). Seriously, it's great for stuff like that.
G.

make full use of LFO's, eg
LFO1 140bpm
LFO2 70bpm
LFO3 35bpm
.....and a tiny bit of random trown in there for evolving base lines.
