Implementing New Channel - A Rudimentary Drum Machine

Objective: Demonstrate how easy is it to expand the functionality using the framework, showing examples of how to:

• add a new channel with any numeric code we want
• enable or disable standard features that are available, to borrow some functionality from other channels
• upload arbitrary data into FLASH memory and access it, this is handy for lot of other things too
• decode binary 16-bit PCM sample data from a standard WAV format
• play multiple instruments in parallel, from FLASH memory with zero waiting state and no need for buffering in SRAM
• bind this new functionality to existing controls
• mix the signal output from our custom function into the loop with or without delay/echo
