      What is the Lisp function for stopping playback (bound to the shortcut cmd-esc)? 
       
      ... I could never add a custom keyboard shortcut to the Opusmodus text editor Hemlock (and I tried), but I just managed adding keyboard shortcuts and a menu for playing Opusmodus snippets and my polyphonic score format to Emacs (thanks to the fact that scores now can be displayed in a separate window). Only need some key for stopping playback as well.
       
      (The main thing I will then miss when using Emacs as the Opusmodus IDE is the close integration of the document, but well, you cannot have everything 🙂  On the plus side, I have a more stable editor and in particular a very good debugger.)
       
      Thanks!

      Hallo,
      newbie here 🙂
      I'm just starting with OM and playing around with the tutorials.
      I slightly changed tutorial #4 and run into something strange.
       
      If i run the script as posted below, all works as expected. But when i change the function reverse to nreverse (and nreverse is the oficially documented name of the function)
      the omn result will leave the right hand empty. Why ist that?  And why does reverse work as i expect it to work?
       
      And, another thing: i dont understand what the term seed will do. Will it make random functions behave always the same as long as the seed is the same?
      ...and what does the number following the seed mean?
       
      Thank you !!
      Best,
      Sebasian
