While waiting, and in case you know what MIDI-OX is (or have other MIDI sniffer), you can check that you have not problems with touch detection.
Connect to X-Touch output (I mean to see what it is sending). For fader 1:
*Movement is PitchBend 1
*Touch is Note 104
Start Sonar. Touch the fader - you should see Note 104 On. Remove finger - Note 104 Off.
Touch, move the fader, remove the finger. You should get Note 104 On, a set of PitchBend 1 events and then Note 104 Off.
If you do not see Note correctly or you see Note events during the movement - the device is not reacting properly on touch.
