LMM DSP software has been revised to fix a bug that caused the ECM to ignore the timing tables for Tunes #3 & #4, instead it used Tune #1 timing instead of #3, or Tune #2 timing instead of #4.
Because it was an OS error this means all existing DSP5 tunes must be scrapped and you have to start over.
Software and further information can be found here:
