GTown is one of the best initiatives ever. I needed a good cymbal, donwloaded the one there and the sound was to die for. It absolutely helped me in the project I was doing. In fact, I couldn´t´help to put the cymbals sound quite too loud because I loved the sound so much.
If I´m able to make my economical situation a bit stable (which is proving to be tough, *shrugh*)PayPal´s site is surely going to receive a visit.
I prefer kontakt format (the darbuka is great) but as long s the gig files doesn´t have any weird mapping which gives any exporting probs (and the cymbals were very easy to export) .gig format is ok.
