Gotharman's SP filter board for Anamono X and Xmini
Based on the output stage of the Emu SP12/SP1200. The input signal is converted to 12 bit digital (switchable to 6 bit for absolute lo-fi), and goes into a 24dB SSM2044 low pass filter. The sample rate can be adjusted and modulated from 0 KHz (audio stopped) to around 60 KHz. On output 2, an analog fuzz effect is added.
