Answer 1

You must derive your class from TPersistent, or a descendant, in order to make it available in the Object Inspector:

TDispPitch = class(TPersistent)
private
  ...
published
  property ...
  ...
end;

From Delphi Documentation:

TPersistent is the ancestor for all objects that have assignment and streaming capabilities.
