Its too easy these days to have 20 VST synths on your machine which you will never have the time to learn inside out. Save up for a year and buy a Virus and goddam it your are going to force yourself to get the best out of it.

At the very least get a small piece of hardware (an electribe) to have by your side and use with your pc. Software is good but for christs sake buy a hardware 'instrument' for the hands on side of things!
