9 DISK
9.1 File Format
Please use the provided 4GB SD Card or a working SD card with FAT32 file system – not
exFAT32 (unsupported due to Microsoft licensing). If you are unsure what file system is
used on your SD card, open the properties of the disk drive on your computer (WIN:
right-click on drive and select properties) and see which file system is used:
Mostly SD cards smaller than 64GB use the older FAT32 system – but it's not
mandatory. The FAT32 file system can comprise up to 8TB disk space but „only“ file
sizes of 4GB. Because of the large video file and hi-res picture demands, the exFAT32
was implemented – and not granted - but licensed by Microsoft. It has no real
advantage for small applications like the Alpha Base however and is even a little bit
slower. Even 4 GB is a LOT of drum samples.
The file format is: *.WAV 48kHz 16bit mono or *.RAW 48kHz 16bit mono.
The Alpha Base only stores in RAW format and only in the root directory. But with any
modern wave editor you can load these samples and edit them.
For reading samples by the Alpha Base, you can use the root directory or create folders
on the SD card that are only one level deep to store your WAV or RAW files in. The
Alpha Base can handle up to 30 folders. Don't create subfolders of folders though, as
the Alpha Base OS can't read them.
You can only create folders on a computer.
Copy the files to the SD card and insert the SD to the Alpha Base.
