The AKAI MPX16 is a something of a 'bare bones' sampler. more advanced than the preceding MPX8 but still fairly limited. Sampling or putting together 'kits' from existing samples using the MPX16 can be somewhat painful and time consuming. After having written something similar for the MPX8, I decided to reverse engineer the 'kit' format and create a utility to take a bunch of samples, format and rename them so they are compatible with the MPX16 and create a kit file from them
You can download the jar and batch file here. It's a command line utility with the following syntax
java -jar mpx16.jar <kit no> <directory of samples> <target drive> [del]
kitno : number for the kit file the tool will generate
directory of samples : directory containing the wav files to be used in the kit
target drive : drive letter of the SD card we're copying to
del: optional command to del any existing wav files in the root directory of the SD card
i.e.
java -jar mpx16.jar 1 c:\samples g del
Will take the first 16 samples it finds in the c:\samples directory, rename / resample them and copy them to the root of the G: drive. It will place them all into KIT001
