well, no doubt pro-audio is a big niche, but it probably pales in comparison to the vast majority of boring lob apps where 100ms latency is fine. james dailey seems to be optimistic, but for some reason, it's not a priority. "As a musician myself I have been pushing to see the platform support round trip latencies in the 15 - 20 ms range. I think that this is totally possible with the current architecture. Unfortunately at this time this really isn't on the roadmap. I will keep pushing and we will have to see how the platform evolves."
personally, i would love to be able to fool around with interface ideas to trigger and sequence sounds in realtime. there should be a petition or something.
