I lost my last computer to a really bad virus. On this computer,I had a Interactive Bass Simulator. It allowed the user to plug in various values, ie: frequency, distance between subs and other values. The user could then 'click and drag' the virtual subs closer and farther apart,for a visual way to demonstrate the Comb Effect. I used this program to educate (or attempt to educate) old school sound guys. Please help me find the link. Thanks
