I'm currently working on a collaborative track with a US producer called Michael Try. It's an atmospheric progressive trance track. Although I regularly use Reason, this track is being made entirely in Studio One Pro, which I bought earlier this year. I'm using Sylenth1, Omnisphere and Reaktor (Razor) for the synths. The drums come from Studio One's 'Impulse' drum machine
I've tried to give real depth and width to the sound.
EDIT 26th Nov 12:
Here's some more of the track...a dubstep section which took about 8 hours to do this afternoon. Razor does most of the bass, Omnisphere does the FX and Sylenth provides the stabs.
