Hi Fernando
If you introduce noise, does voice#1 work?

  Hello all.
  After switching the machine on, here is the problem: 
  MIX I : everything works fine. I move the "channel" selector down to Mix II 
  MIX II: panel and memory do work as well. Only the Preset buttons show the following fault:
  when I play the first note it does not work (sometimes it seems to fire a note, but at a very low level... ), the following 6 in a row do work. then the following does not work, and so on. 1 yes 6 no. 
  Moreover, when I keep the first (faulty) key down, and play another key in a repeated sequential way, all of the notes are normally heard. 
  I tried to move and check the boards' cables, no clue. The fact that all of the voices work when panel or memory 2-4 are switched on means that the voice board of the first note (21)
  is not faulty. Do I have to check at T54 or BA?
  Please help me! 
  Ciao
  Fernando from Italy
