Library Storage Example

This example loads and plays the six effects shown in Figure 15 through Figure 20 into the waveform RAM. This is a simple example of how to put multiple waveforms in memory for subsequent low-latency recall. It is generally good practice to put the waveform header in page 1, and the waveform data in the following pages. When new waveforms are added later, the waveform data does not need to be shifted when this practice is used. Although this sequence seems long with the verbose descriptions, this example only takes 121 bytes of the waveform RAM, that is 6% of the available on-chip memory.
