Hello, I am working on a MIDI controller with LED displays and I would like to use a backup file (format .hls) to retrieve the name and footswitch default status (i.e. what FS is on/off for each snapshot when I go to the preset or change snapshot etc). Since I don't change my setlist that frequently I am not trying to read directly from the unit but instead hard code the names and behaviors based on the .hls. I use a JSON parser to decode the .hls file and see there is a section called footswitch Here is an example (see full file in attachment) 'footswitch': {'dsp0': {'block0': {'@fs_enabled': True, '@fs_index': 5, '@fs_label': 'Volume ' 'Pedal', '@fs_ledcolor': 65408, '@fs_momentary': False, '@fs_primary': True}, 'block1': = etc.. Based on that, I originally assumed that each @fs_index would refer to a footswitch with @fs_enable for the status. However, that doesn't seem to be the case because I have a few setups with @fs_index > 5. To make things more confusing, I also see some presets without the 'footswitch' blocks though there are setup in the unit. Has anyone be able to understand how the hsl file work for the foot-switches assignment ? Any guidance on how to interpret the structure of this file ? Thank you. Pat. Test.txt
