Under the button pad is a piezo element, which appeared in the building journal. These devices can operate as devices that sense pressure changes, such as a finger strike and they can generate a sound when electricity is applied. Arduino pins can switch between inputs and outputs, so it was no trouble to use the pressure sensor as sound output, but not at the same time. When the unit started, it chirped after all the startup algorithms were complete.

As the code grew, some of it moved to functions. An experienced programmer probably would have done this from the beginning.

The third mode to be programmed was the most important for the whole drum machine. Loop mode allowed a user to enter a sequence of instruments to play repeatedly. The notes all fit into the time slice determined by the tempo, so adding will shorten the time between them.
