Hi there -- I'm currently working on making a simple MIDI organ pedal by using the parts from an old Casio keyboard hooked up to a set of Hammond organ pedals. I'd like to give this project a little aesthetic appeal...what I'm envisioning is using a plexiglass top on my pedal board casing so the 'guts' can be seen. No problem there. However, I'd like to have a light be triggered inside the casing when a midi note is triggered. I'd be satisfied if it were a single light or a set of lights. I'm thinking about using a small lightbulb rather than an LED - something that can be seen from the crowd but not be too distracting. Would anyone know how I might do this?
