muP-controlled mixer board (2):

This second and final part of the audio mixer board deals with the construction and the control of the board via a PC. To do this, all that needs to be done is to connect the board to the computer via a simple three-wire link and exchange same of the hardware by some intelligent, free software. This arranges for the mixer board to appear on the monitor, where upon it can be controlled by the computer mouse. This part starts, however, with the construction of the board.
