Some of our older products have been discontinued and so we no longer distribute them nor have the old files for them anymore. Some of the programs you mentioned however can be found here:

We do sell these ones on the page we linked you which do include MIDI files:

  • Latin Pianist
  • Modern Jazz Pianist
  • Blues Pianist
  • New Age Pianist

But the Jazz Pianist in particular we no longer offer nor have the old files for - just the Modern Jazz Pianist.
