The OpenMPT/libopenmpt project released the latest stable libopenmpt version:

libopenmpt 0.2.8760-beta27 (2017-08-12)

  • [Bug] libmodplug: The CSoundFile::Read function in the emulated libmodplug C++ API returned the wrong value, causing qmmp (and possibly other software) to crash.

  • The ProTracker note delay quirk should not retrigger already stopped samples (fixes “Subi loses the Cops” by Subi).
  • ProTracker portamento between already stopped sample and another sample kept playing the old sample (fixes “anarchy-main” by Jester).
  • Playback fix for instruments with custom tunings and transposed note maps in MPTM format.
  • ProTracker quirk: If there is a note with a out-of-range note delay, it is played on the next row (with an instant portamento), unless there is a new note on that row.
  • ProTracker quirk: Apply tempo changes after the first tick of the row.
