The notes are fine in the BB file, and would trigger an instrument placed in the drum kit at those locations, midi 107, 108, and 109. (B6, C7 and C#7). You also have a little part going on between C6 and G6.
If your Nord acts like a software sampler works, it may be transposing the notes you intend to use for a click to a higher octave and, thus, shortening the notes. If I were to place a wav in Logic’s sampler, and logic detected it’s actual value as C1, but I then tried to trigger it within the sampler at C7, I would get a very high pitched short note, as the wave form would be compressed to reflect the change of being 6 octaves higher. In Samplers, you can “trick” them into playing a higher note at the correct octave, by telling the sampler that the root pitch it actually the much higher pitch (or whatever pitch you want it to be), or by having the Sampler treat the wav as something that does not respond to pitch values.
Here is an example from Logic’s Sampler. Your Nord must have similar settings somewhere:
I have a wave called 72 Long Whistle. Logic brought it in as a Pitch detected at C1. I assigned it to C4. But, if you look closely at the Playback settings, Pitch is not active, so the Sampler is not adjusting the pitch. It plays the wav back at its recorded pitch. I believe since you are hearing short tick-like notes, your Nord has treated your click track tones as material which is having its pitched transposed.
If you just play a B6, C7 or C#7 from the Keyboard going into the Nord, do you hear the click track tone at the correct pitch and length?
