Patches

Currently, the Wave mode is the only mode that stores patch data. All patches are stored in a single file on the SD card in the root directory in a file simply called patches.txt. It is a text file that is in a special format, which is as follows:

name (16 characters, padded)
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 higher. 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:

There are currently 32 patches, and each patch uses the above format with the next one immediately starting on the next line (there is no blank line in between patches).

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.
