Patches

Currently, the Wave and Sample modes are the only modes that store patch data.

Waves

Wave patches are stores in the waves sub-directory off the SD card. The filename is the name of the patch and should be 16 characters or less in length.

Each patch file contains the following:

step sequencer method (F, B, P, R)
wave-1
...
wave-16

Where wave-# is a sequence of 32 hexadecimal characters (0-9,a-f) indicating the value of the sample at that position of the wave. 0 is the lowest, f is the highest. It should be noted that WaveBoy outputs a bi-polar signal, so the center is in-between values 7 and 8.

Here is a full example:

Patches can be edited on WaveBoy directly using the knobs while in the Wave viewing mode (see Wave Mode). In the project source there is a python script that generates the patches that come on the SD card by default. This can be edited to create different patches, or patches.txt can be edited using any text-editor. Just be sure to follow the file format specification as there is currently no error checking on the patches.txt file.
