With a real whistle, as you blow harder the pitch increases as well as the volume. Can WARBL model that characteristic?
Only if the sample library or software it triggers have that quality.
WARBL only triggers pre-existing sounds, it doesn't generate any sounds on its own.
So for example Michael Eskin's "celtic sounds" sound set, for IOS, behaves differently from the Native
Instruments Irish whistle sample library that I use with Logic Pro. Native focused on airiness and "chiff" at the expensive of sliding. Michael Eskin's soundset, which I think is maybe generated by software rather than recorded samples, does "slides" much more effectively. If I wanted to make a realistic sounding whistle recording using WARBL, I might double the midi track and play both simultaneously. Both of those appear to be pitch corrected, but I haven't checked it closely. If I wanted to simulate that behavior I'd maybe add it after recording by slightly sharping higher notes. I'll check it today if I get a chance. There are other Irish whistle sample libraries that claim to be more realistic.
WARBL does require more pressure to jump into, and stay in, the second octave. How much more is adjustable in the software. It doesn't have a whistle mouthpiece, just a tube. You could probably adapt a whistle mouthpiece to fit, though
I just did some more experimenting with the "celtic whistle" sample set that comes with Logic Pro. It's much better for "slides" than the Native Instruments library. But it's hard to play a quick reel with clarity and the slides tend to take a more time to develop. I don't know actually if this is WARBL or the sample library software, or the fault of my technique.
WARBL isn't exactly like a whistle but it's pretty close
