You have to import the presets via the “Preset Action” menu. Press the Select encoder to open a pop-up menu in the display. Here, you can select the desired options and confirm by pressing on the Select encoder:

Start Receive: Puts Protein in a receive mode for multiple sound presets as MIDI SysEx dump from any external MIDI source. Here, you can set the slot from which onwards received presets will be stored. No existing presets will be overwritten but instead the next empty slot chosen. You must either confirm or cancel the final start of the process.

For macOS, there’s a handy free tool called “Sysexlibrarian” that you can use. For Windows, there’s “MIDI-OX,” which is also free. In the download section, you’ll find “Sysex-Drop,” which you can also use to send Sysex data to the Protein. The delay between packets should be set to at least 150 ms. Sysex-Drop is available for both Mac and Windows.
