MICrODEC
Stock Functions
The MICrODEC comes preprogrammed with 16 functions. These feature a number of the things the MICrODEC does well, including time effects. For the most part, these involve looking up some data in the SRAM and multiplying or adding it with some other data, before playing it out through the codec. A zipped file with all of these is linked off the main MICrODEC page, and here you can you study each function in-depth (understand how each works, and steal bits of code for creations of your own).
