thats a request dump request or send snapshot functionality.
jomox airbase can be set to send all CC’s on program change, very handy.
its the only synth I know that has this feature. thus allowing easy bidrectional controller control without any sysex parsing.
afaik AR does not support sysex dump requests afaik. this was in earlier days standard for most MIDI synths. seems to me its not common anymore.
