Please see (example) in KEY_PAD_1,

  SliceNum_3  : CONSTANT Integer := 31;
  StepNum_3   : CONSTANT Integer := 14; --Upstream placemoves
  RepeatsNum_3: CONSTANT Integer := 6;  --Repeats
  -- scrambling device in 'Load_n_scramble_Pad_3' procedure
  -- SliceNum_3 + StepNum_3*RepeatsNum_3 <= 126.

Please leave "SliceNum" unchanged and only change the other two (product of these must be <95)e.g.

14 x 6 = 94 (<95 ok)
a change might be 23 x 3 = 69 (<95 ok)
or say 7 x 12 = 84 (<95ok)
etc, etc

Changing 'SliceNum' requires program source code changes (not essential).

Thanks - Austin
