Would a Roland module have less latency than an Alesis D4?

I imagine the Roland modules (particularly the newer ones) will have lower internal latency, since it was one of the bullet points in the feature lists for the TD11, TD15, and TD30. I think MIDI latency is around 4ms for those modules.

As for your bass drum, what's happening is that when unmuffled; you're getting a lot of additional vibrations and resonance causing false triggering, because the signal isn't very clean. You say you've tried tweaking your Alesis D4? - I don't know if it has the settings you need to fix this in that case, or it just can't interpret the Roland trigger properly.

You should be able to gain reliable triggering regardless the drum, providing you have it dialled in. Again, I imagine if you had a Roland module that officially supports the trigger, you'll be able to solve that.

By the sounds of it, it looks like the Roland TM-2 was made for you. 2 inputs, to enhance bass & snare on an acoustic kit.

IMO running kits directly from the module, I experience virtually no latency. However, running VST sounds is another issue, particularly on my quite limited laptop's sound card.

It will be faster than the 1991 latency that the D4 will have but swapping to a Roland module seems a bit expensive for just a trigger interface,
