Uhh.. so I installed the demo, and it recognized maybe two of my VSTis. The search path is set correctly. I'm not sure what's going on, does anyone know how I can get everything to load in the browse panel?
Are you using the 64-bit demo or the 32-bit demo? 32-bit VSTi's won't show up in the 64-bit version of Studio One which is true 64-bit (no smoke and mirrors)
