That's what I though when I first read up on the subject, but its not crossover as in filters, its crossover as in amplifier switching. It's caused by the zero-crossing correction in class B and AB power amplifiers. Aparently its an important part of the sound of guitar amps. http://www.google.com/search?q=%22crossover+distortion%22 Your compressor would be most welcome as a LADSPA plugin. There is a distinct lack of compressors at the moment. - Steve
