  Since everyone is contributing their tuppence and personal hacks:

  I've modified a non-current version of qsynth to provide routing and
  also I also start 3 engines -- qsynth1 ( right-hand of keyboard ),
  qsynth2 ( left-hand of keyboard ), and qsynth3 ( Yamaha DD-55 drum toy).

  The routing is variable via new settings values for qsynthrc --
  MidiHighKey:  highest input note (1-88) handled by the engine being configured
  MidiLowKey: lowest input note (1-88) handled by engine being configured
  MidiOutputMask:  hexadecimal mask of output channels for the engine being 
configured.
  MidiInputChan: an integer describing what input channels should be handled by 
the
                 engine being configured.  If this value is a positive integer 
than the
                 engine handles only that channel.  If it's zero, it handles 
any midi channel.
                 If it's less than zero then the engine will handle odd 
channels if it's odd (-1)
                 and even channels if it's even (-2).
                 
  MidiOutputMask is be used for simple layering, by specifying multiple 
channels in the mask.
