-     - info_type: The kind of information you're going to send. ("VOLUME", "PAN"...) Defined on `nihia.mixerinfo_types`
+     - info_type: The kind of information you're going to send as defined on `mixerinfo_types`. ("VOLUME", "PAN"...)
+         - Note: If declared as `"EXIST"`, you can also declare the track type on the `value` argument as a string (values are contained in `track_types` dictionary).
     
      - trackID: From 0 to 7. Tells the device which track from the ones that are showing up in the screen you're going to tell info about.
 
     The third (and last) argument depends on what kind of information you are going to send:
 
-     - value (integer): Can be 0 (no) or 1 (yes). Used for two-state properties like to tell if the track is solo-ed or not.
+     - value (integer): Can be 0 (no) or 1 (yes). Used for two-state properties like to tell if the track is solo-ed or not (except `"EXIST"`).
