"Why math? This module is based of an 4bit arithmetical-logical unit (ALU). It has clock and Start/Stop inputs and 16 trigger outputs - for each value of the 4bit result. In case of the output value they're numbered from 0-15, not 1-16 as usual. some combinations give a trigger at each output, but in different sequence ;) How it works: The ALU has two 4bit operands, which values you select by the two rotary switches. It has a 4bit operation selector itself and a arithmetical / logical switch; and a 4bit result output. The operation itself is clocked by a 4bit counter - does the 16 notes in 16th for a bar - and the result of each step goes to a line decoder (4bit to 16 lines), visualized by a 4x4 LED matrix and out to 16 separate outputs (4V TTL, near 1ms puls width). PS: don't look at the 'cooler' at the pcbof the proto ...
power is curetronic, i can do a DotCom Adatper."
