In the Supernatural drum sounds in the Integra-7, there's no way to articulate the hihat opening, the physical samples are not there. But closed and opened hihat sounds are well articulated themselves in their range, no audible sample layering, no sign of a discrepancy in the entire velocity range of these elements, it's just that it's not meant to respond to the e-hihat pedal opening, the #cc involved is not mapped to any change in the opening.
Other Integra-7 Supernatural drum sounds have no articulation at all : snares and toms for instance have rimshot sounds, but they aren't articulated at all, it's only on/off, and that makes a huge difference in play-ability with the TD-30 for instance, where there are hardware rim sounds, hardware+rimshot sounds, and they all interact with each others and with the playing. In comparison, the Integra-7 hosts some of the TD-30 sound flavor (no machingunning on the snares for instance, and some tones are adapted from the TD-30 SN sounds), but they remain GM style drumkits.
For snares and toms (except that I-7 toms have no hardware shell noises and they are none in the entire module to layer/crossfade etc.), it's ok because you can assign rimshots to the rim and plain shots to the head and it's just fine. For cymbals you can refine and assign velocity crossfades to simulate the bell and various crashes (I liked to have as much sound variety as I could on cymbals, so used fine programming to maximize that and it was efficient), and layer kicks as well, and even simulate the brushes quite convincingly, but for the hihat it was problematic as nothing was doable at all, it was only opened or closed (with action of the pedal of course, but no half opened nor any of the hihat opening ability. That was the major issue using the I-7 as a MIDI drum module for an e-drum kit.
And the PCM sounds were no consolation to that, they sound totally otherwordly to the Supernatural drumsounds in the I-7, so much that even if you could craft a skilled velocity crossfade hihat using PCM sounds on several channels, it would not integrate at all with the SN drumkit.
When you play the TD-30 kits on the keyboard in contrary, you realize all its richness in articulations, resonances of all sorts, even on PCM kits on the TD-30 (those who are in the TD-12 as well), it's leaps ahead from the GM style drum kits on the Integra-7. That's why in the end, it's better to make it very clear : the I-7 drum sounds, especially the SN ones, are very good, and they can be played via an e-drum kit satisfyingly (if you accept you can't half open the hihat) and even with some great refinement to a very satisfying level, but it's nowhere as good and expressive as a proper drum module or sampler.
I was satisfied with the I-7 played from an old TD-6 kit, for about 6 months. It allowed me not to use the computer and the SD2 copy I had back then, it was good enough so that I didn't need that to practice, but as soon as I could find a second hand TD-30 kit, I jumped on it, sold the TD-6, and never looked back at the I-7 as a drum module (nor did I ever went back to the SD2 or even SD3). The TD-30 is that good an expressive drum brain, it sounds somewhat "Roland synthetic" yes indeed, but it blends incredibly well in a context, and played alone, it's more expressive and subtle than SD, BFD, Slate drums, and other software solutions. And it has been so for nearly 5 years now, I never considered upgrading it, every time I switch it on, it's there, as good as in day one.
This is why I wouldn't suggest purchasing the I-7 for e-drumming.
I kept the I-7 however for my primary use of it : its SN pianos, although they don't have strong pedal string resonance, are the only ones I can play everyday for practice on my old Kawai silent upright piano keyboard without getting bored with the sound. I tried about anything else, but it's the only piano that behaves properly, sounds good enough to motivate to practice and play without getting lured by the sound too beautiful to be true, and sounds spot on perfectly in a context. Other I-7 are great, but alas the internal digital mixer of the I-7 is not very good, and you end up with mud when you start layering sounds or mixing inside of it (it has 8 outputs though so it's something you can work around), but its pianos are really the best I could find in a hardware module. Yes I'm still basically stuck with the sound n°1 in this module, since day one, it has 6000+ other patches I only rarely browse, and I'm not nearly close to begin being fep up with it, isn't something this I-7?!!
Sorry for the long development, but again, I-7 for MIDI drum module yes it works and offers great sounds, but no it can't replace a proper dedicated drum module of software because it lacks articulations that cannot be replaced (hihat).
Now if someone proved me wrong about the hihat articulation in the I-7, I would be very happy to learn that, and I would have no problem admitting I was wrong and congratulating the hihat I-7 champion, so don't be shy about it if the case!
