Howdy I've been "bi-platform" for awhile here. Mainly a Mac guy but there are some really nice application for the PC as well. Mine has to be the D-Lusion Rubber Duck. The SOUND that comes out of it is "GIGANTIC AND TREMENDOUS"* So, what software synths do y'all find to be to your liking? *a phrase I once saw on the nameplate of an incredibly expensive looking Yamaha Turntable.
