I have been working on a concept in my head for a little while now, if this has been done or talked about please point me in the right direction. I have been exploring using a computer to generate effects for music live. Have found some software that will do it called, Native Instruments Guitar Rig. The biggest issue I have with the software is after the demo runs out it cost nearly $600 to buy with the foot pedals. this is currently far out of my budget. In my head I have been rolling around the idea that it should be relatively easy to build a stomp box that connects to a computer via USB that can issue some kind of command or commands to the OS that can be picked up by effects software. A few things I am trying to figure out. 1. Is there another software that will do the same job or something similar that I have not been able to find? 2. Does anyone else want or need this kind of interface? 2a what Platforms would you want supported? Windows, Linux, Mac OS, iOS, Android 3. What would you want this thing to do? Effects, options, contols, what?
