It's kind of a "hole" in Reaper. But really not a problem. There are TONS of great freeware VST Instruments and Soundfonts available. It takes some time, but you end up with instruments you like and can use rather than a bunch of junk. There some wonderful FREE orchestra soundfonts available. Google is your friend! I also use a lot of MIDI hardware, and recently added a Roland Integra-7 to the rack. But VSTi are nice to fill in and for use on a laptop outside of the studio. You might buy a copy of Computer Music magazine. It's loaded with some decent VST and VSTi on a DVD with documentation and tutorials. Welcome to Reaper and the forum!
