It's now possible to use mokucli to download the instrument bitstreams using:

mokucli instrument download <MokuOS_version>

This will automatically make the bitstreams available for all API packages.

Users can also use mokucli to download bitstream files to a specified directory.

To do this, run the command:

mokucli instrument download <MokuOS_version> --target /Path/to/directory

The bitstream files will be available in the instrument folder at the specified location.

If the --target method is used, it's required to set the MOKU_DATA_PATH environment variable to the path that holds the bitstreams.

For Python:

Provide the path to the Python client

For Linux/macOS:

export MOKU_DATA_PATH=/path/to/bitstreams/directory

For Windows (Command Prompt):

set MOKU_DATA_PATH=C:\path\to\bitstreams\directory

For Windows (PowerShell):

$env:MOKU_DATA_PATH="C:\path\to\bitstreams\directory"

For MATLAB:

In the MATLAB command window, run:

setenv('MOKU_DATA_PATH', ‘/path/to/bitstreams/directory’)

Previously, this was done through the API site, which is still available for older firmware versions ( < MokuOS 4.0.1).

You can manually download the bitstreams for legacy firmwares at the bottom of this page.
