"It is possible to optionally provide a single [dict] argument to this function, containing a single key-value pair: the key is "return" and the associated value is a list of the note properties as listed above in the discussion of the returned note dictionaries, e.g. ["note_id", "pitch", "velocity"]. The effect of this will be that the returned note dictionaries will only contain the key-value pairs for the specified properties, which can be useful to improve patch performance when processing large notes dictionaries."

 function on a clip with notes in it. I want to make use of filtering functionality through dict argument as explained in the docs.

var filtered_notes = clip.call("get_all_notes_extended", { return: ["note_id", "pitch", "velocity"] });

post("filtered_notes", filtered_notes, "\n");

var notes_raw = clip.call("get_all_notes_extended");

As seen in the screenshot, "notes_raw" has expected values, however "filtered_notes" is 0.00 for the same clip object. So filtering with dict object with return key, as explained in the docs, is not working for me.

Edit: I also tried code below after learning about Dict objects of Max. However, it is still returning all of the keys like 

var note_filter = new Dict("note_filter").set("return", ["note_id", "pitch", "velocity"]);

var filtered_notes = clip.call("get_all_notes_extended", note_filter);

From documentation for get_all_notes_extended: 

"It is possible to optionally provide a single [dict] argument to this function, containing a single key-value pair: the key is "return" and the associated value is a list of the note properties as listed above in the discussion of the returned note dictionaries, e.g. ["note_id", "pitch", "velocity"].

I am trying to make use of new "get_all_notes_extended" function on a clip with notes in it. I want to make use of  filtering functionality through dict argument as explained in the docs.

What am I missing here?
Thanks!


Edit: I also tried code below after learning about Dict objects of Max. However, it is still returning all of the keys like notes_raw above, and not filtering anything:

var note_filter = new Dict("note_filter").set("return", ["note_id", "pitch", "velocity"]);
var filtered_notes = clip.call("get_all_notes_extended", note_filter);

From documentation for get_all_notes_extended:

filtering-properties-for-getallnotesextended-return-values-is-not-working

Solution found: Apparently, I should have use "set" method on a seperate function call, like below:

var note_filter = new Dict("note_filter");

note_filter.set("return", ["note_id", "pitch", "velocity"]);

clip.call("get_all_notes_extended", note_filter);

var note_filter = new Dict("note_filter");
note_filter.set("return", ["note_id", "pitch", "velocity"]);
clip.call("get_all_notes_extended", note_filter);

Filtering properties for get_all_notes_extended return values is not working
