Back in 2003 I was briefly obsessed with an idea for a ridiculously flexible tremolo effect that would allow the LFO wave shape to be almost anything you wanted, and I'm now I'm thinking about actually building it. While it would obviously be applicable to guitar, I think there are other musical uses.
To get beyond triangle, square, sine & pulse shapes I'll generate the LFO wave shape with a microcontroller. I want to control each phase individually, a la ADSR envelopes: shape1; hold1; shape2; hold2. In addition, each of the shape phases could be any straight line slope or any 1/4 sine wave slope (speed, really), parabola or other interesting 2D curves. I'm even going to play with drawing the LFO forms. I also have ideas for a few different depth control modes.
There are all kinds of things to resolve, and right now I'm thinking about the 'user interface.' Are there super-flexible Tremolo or LFO units already out there that I should look at? Am I insane?
