[sdiy] Modeling circuits

[Tom Wiltshire]

Aren't the Line6 pedals based on the Freescale Symphony DSP? I'm pretty sure the Tonecore range are, at least. Perhaps some of the other stuff has more horsepower.
Whatever, they're all basically a codec chip and DSP in a box, so they can do whatever you can be bothered to program. Hence the multiplicity of "vintage amp models" and such like. Since realtime FFT is practical on a DSP even of this size, I'd have said that they *could* apply different amounts based on input character if it was desirable - whether they *do* or not is presumably commercially sensitive information.

For me the most interesting thing they do is the Tonecore pedal dev kit:

One day when I'm feeling flush I might get one of these.
