I don't know about Gossett, but Dex and I did this on our Cook-Morrill trumpet interface, and I think the CNMAT/Gibson/Zeta project did this as well. On ours, we fired a noisy attack on one MIDI channel as soon as we detected playing over a threshold. Then we waited a fixed time (like 100 ms) and collected pitch info from many sources (valve info, lip tension, and acoustic features from two mics). Then we fired a best- guess pitched noteon on a different channel, and updated that with bend messages. We sent a note off on the attack channel. There was no perceived latency, but there was occasional monkey business on the pitch update side. Prc Ref: http://quod.lib.umich.edu/cgi/p/pod/dod-idx/midi-control-and-performance-sys...
