A method for generating a sustained melodic sound from the sample channel:
As mentioned in the video, The Immortal by Rob Hubbard is the only soundtrack on the NES or Famicom I’ve found that uses this technique, and I’m under the impression that it is truly unique. Please send me a message if you know of any other examples!
For the famitracker users, you can download an instrument I’ve created that maps the sample to the corresponding notes on a piano for all 16 pitches. The lowest notes start at octave 3 for convenience: DPCM Rob Hubbard Saw.fti
