Preallocate object array problem: Toolbox Path

I would like to preallocate a array of 'track' object.

The problem is that: The 'track class' is inside my toolbox called 'mix'.

My toolbox path is: .../Documents/.../Mix Toolbox/+mix/@track/track.m

Here is the class:

classdef track < handle

    %TRACK Define the audio track object
    %   The track object will store the signal and
    %   all metadata of the audio file

    properties
        name
        signal
    end

    methods        
        function this = track(file)
            %CONSTRUCTOR Construct an instance of this class
            %   Init the track object:

            fprintf("Loading: %s \n", file.name);

            % Get the track name:
            this.name = file.name;

            % Read audio file:
            [this.signal, ~] = audioread(file.name);
        end
    end
end

I'm trying do this:

N = 1000;
array(1, N) = @mix.track;

And I got this error:

Nonscalar arrays of function handles are not allowed; use cell arrays instead.

How can I preallocate a N array of this object?
