JSampler and QSampler both control the sampler purely via network protocol
(called "LSCP"), in this case it is this LSCP command:

SEND CHANNEL MIDI_DATA <midi-msg> <sampler-chan> <arg1> <arg2>

MIDI note-off is [1]:
1000nnnn 0kkkkkkk 0vvvvvvv

MIDI note-on is:
1001nnnn 0kkkkkkk 0vvvvvvv

MIDI control change is:
1011nnnn 0ccccccc 0vvvvvvv

Where
  nnnn is the MIDI channel number (0..15)
  kkkkkkk is the key/note number (0..127)
  ccccccc is the controller number (0..127)
  vvvvvvv is velocity (note-on / note-off) or
          the new controller value (0..127) (control change)

Note:
  - Note-On with velocity 0 means "note-off".
  - MIDI allows to omit the status byte on subsequent messages, which is
    called "running status". That's basically just a simple way of data
    compression [2].
