Hello. I'm want to make a gliscendo with the trombone and authers instruments. What is the default for descend for one subtones, one tones and etc... Thank you for your helping...

The range for pitch bend is (numerically) -8192 to 8191.
The unofficial default for MIDI is for this to be -2 semitones to +2 semitones. This value can often be changed by special control messages (can't be done in NWC, but can be added later by a MIDI sequencer program).
I think you'll find that -1 semitone is -4096 and +1 semitone is +4095. I'm not sure that the correspondence is guaranteed to be linear, but I think Fred found out that it was anyway.
