Re: [TCML] The Hammertone Predikter

Opticals are nice ---- fast turn on, but it doesn't turn off that fast.
Even in an LED circuit, opticals don't dissipate as fast as they come on.
This is a typical problem in optical switching, especially at high frequency
operation.  This could result in a limited output.

Your efforts to explore this area are interesting.
