Welcome to the SPJHELPER Page

SPJHELPER software was developed as an aid in the construction of "Sound Projects" for the Digitrax SFX sound decoders.  The program operates in two modes: one for simple non-technical design of Sound Projects, and the other for the experienced programmer wishing to use easy access to the necessary tools.  Four example sound projects, designed using the simple design mode, are included with the installation.
