The heart of the MP3 trigger board is the Cypress PSoC CY8C29466-24SXI microcontroller, which delivers MP3 data to a VLSI VS1063 Audio Codec IC. This version also supports an optional initialization file that can be used to set the baud rate of the serial port and re-program one of the 18 trigger inputs to alternative functions, including random and sequential track selection, transport control and even volume up/down. Any traditional trigger can be set to either allow an instant restart or disable the restart when audio is playing. In addition, a new trigger file naming convention offers more flexibility in naming your MP3 tracks and facilitates file management.

There is also a "quiet mode" function that can be activated via the serial control interface. In this mode, trigger inputs do not start tracks directly, but generate a serial message indicating which triggers have been activated. A host microcontroller can thus monitor the trigger input and then start any track or sequence of tracks via the serial control interface, making the triggers much more flexible.
