microSD Card Specifications
• We include the ideal type of card to use with the Sampler. If you need to buy an additional card,
we highly recommend that you purchase the same class of card. The Sampler works best with
a UHS Speed Class 3 card (also known as U3, which is the fastest of the UHS-I type cards).
Look for this symbol printed on the card:
•
• Example card: SanDisk Extreme microSDHC UHS-1 Card (advertised as "Read up to 60MB/sec,
Write up to 40MB/sec")
• If "UHS Speed Class 3" is not available, a "Class 10" card is acceptable (booting will be slower,
and there may be more latency when playing 96kHz/32-bit/stereo files at high Pitch settings)
• A Class 10 card will be slower than a UHS Class 3 card. A class 6 or
class 4 will be even slower than the class 10. If you are not using the
Sampler to record long samples, and you only playback 44.1kHz/16bit
samples, then even the slowest microSD Card available will work fine. However, we still
recommend purchasing a high-quality microSD Card, as cheaper cards are not as reliable and
may result in loss of your data.
• See https://www.sdcard.org/developers/overview/speed_class/ for a discussion on micro SD
Card speeds and labeling
• Never remove the microSD card while the Sampler is playing or recording.
How to prepare a new microSD Card
• Purchase a UHS Class 3 card (see above)
• Format the card as ExFAT (preferred) or FAT32
(acceptable). See screenshot (right) for how to
set MacOS standard "Disk Utility" program.
• Verify all sample files are valid WAV files (see
file format specifications below)
• Put your WAV files into folders to organize them
into banks (preferably 10 WAV files per folder)
Each new folder found will represent a bank.
•
You can name the folders beginning with
the name of a color (such as "Yellow-field
recordings") to force that folder to load into
a particular color bank.
Sample files must be located directly in the root directory, or in a folder. Folders inside
•
folders (sub-folders) are never scanned by the Sampler.
File Formats
The Sampler recognizes the vast majority of WAV files. Verify that your files meet the following criteria
(all others will be ignored):
• Format: WAVE
• Bit depth: 32-bit float; 16, 24, 32-bit signed; 8-bit unsigned
• Channels: Stereo or Mono
• Sampling rate: 8kHz to 96kHz
• File name: Must end in .wav or .WAV
• Folders: files must be in a root-level folder (sub-folders are ignored)
• Limitation on file names: The maximum file name plus full path cannot be more than 80
characters. File names that are longer in 80 characters (including the ".wav", the folder name,
plus a "/" for the separator) will be ignored.
