A simple extractor for the samples in the P3A files generated by the KaossPad 3+

This is a simple parser for the files that are produced by the Kaoss Pad 3+.

I needed to extract the audio stored in a slot from the data saved directly by the KP3+. Luckily it was pretty straight forward! The file extension for this file is P3A. It is stored in 512 byte pieces, likely for the sector size of the SD card. If a chunk is less than the sector/block size, it'll be padded with 0xFF.

The example program reads the P3A file and then writes out the 4 samples as .WAV files. They are stored at 48000KHz 16 bit, Stereo LE format in the .WAV file, swapped from the BE format used on the KP3+.

I haven't yet figured out the rest of the settings, but I know that the PROG fields correspond to the 8 stored FX buttons and that the GLOB field contains the rest of the settings information. For example, I think the tempo is a 16 bit BE field at offset 19 from the start of the GLOB chunk, but I'd have to do more work to map out all of the options. A task for another day!

Hope you find this useful!
