Once MIOS and the MIDIO128 application have been uploaded, each digital input will send a Note On event (pin 1-64) or Controller Event (pin 65-128) when a button is pressed (=0V at the digital input pin), and a Note Off event (pin 1-64) or Controller Event (pin 65-128) when the button is released (=5V at the digital input pin). | Once MIOS and the MIDIO128 application have been uploaded, each digital input will send a Note On event (pin 1-64) or Controller Event (pin 65-128) when a button is pressed (=0V at the digital input pin), and a Note Off event (pin 1-64) or Controller Event (pin 65-128) when the button is released (=5V at the digital input pin). | ||

If the first input pin of the first shift register (74HC165) triggers all 128 Notes at once, there is propably a problem with the Shift or Register Clock line (SC/RC signal). Both signals are driven by the core module, and they are connected to all shift registers in order to scan the chain. If these signals are not connected, or if there is a short, the core will always " | If the first input pin of the first shift register (74HC165) triggers all 128 Notes at once, there is propably a problem with the Shift or Register Clock line (SC/RC signal).

Warning: Don't do this too early, this should be the last measure which normaly leads to success, but also to a bad looking PCB. After this procedure, you have to repair the track with some solder | Warning: Don't do this too early, this should be the last measure which normaly leads to success, but also to a bad looking PCB.
