The new 3.0 version of the Style Converter software can now be downloaded from Roland and the only difference from the previous version (for the GW-7), are the extra Style variations that are available in the GW-8.
I currently own the GW-7 and have been more than pleased with its performance and utter simplicity. I really do like the GW-8 for what it is (a simple arranger workstation with great portability, polyphony and sounds) and was planning on its purchase...but after spending time playing around with Logic Studio and various soft synths, I am looking more towards a portable synth workstation like the Korg M50. I definitely do miss the Fantom S and X I once owned and the GW-7 was only meant to be a "filler" instrument until our finances changed, which they thankfully have! Still have to keep it tho' for the daughter, who loves to tickle the ivories when she visits every couple of weeks (she taught herself to play and she's in her mid-twenties!). I am using an Edirol PCR-50 with my computer upstairs and it really sucks but definitely better than nothing!
I am just ready to switch directions and try something different. Worst case scenario is that I'll use it for a year then move on but with the Karma possibilities of the M50, I don't think this is too likely. Should be fun!
