Rendering procedure

  • Make the instrument patches for a sampler using RWC samples of three dynamics (ff, mf and pp). (Download the onset marker files of RWC samples)
  • Separate each MIDI instrument track from the original MIDI file, retaining the tempo track and all control messages and channel messages.
  • Split each instrument MIDI file into separate tracks such that the rendered samples don't overlap.
  • Render each monophonic track using a sequencer+sampler system.

Why not using MIDI notes as reference?

  • The end of MIDI note is usually not the end of rendered signal. (see the figure below)
  • The MIDI note does not provide precise F0s.
