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.

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.
