OP–1 field uses the media transfer protocol (mtp) as primary method to import and export content such as drum / synth patches and tape files.
mtp gives a host computer fast and direct
access to the content of OP–1 field, by using an optimized flash file system.
linux, windows 10 and 11 has native support for mtp.
plug in your OP–1 field and enter mtp mode to automatically mount the unit and get direct access from windows file explorer / file manager.
macOS does not support mtp so a tool is needed. therefore we have released the field kit utility which provides a finder integration for OP–1 field.
for macOS is the application used to import and export content from the OP–1 field.
