Dear Benjamin, we will have a paper in this years SMC conference related to the acquisition of tapping data using software implemented at INESC TEC in Porto. We did an experiment to determine the overall latency when using a MIDI interface (Roland Handsonic HPD-10) connected through a Digidesign USB sound card to a 2012 iMac. The obtained latency was 17ms. I do not know how much you can gain by using more high end interfaces, but I would agree with the previous response, that it is very unlikely to get even close to sub-millisecond accuracy using MIDI. Please let me know about your further investigations, contact me if you like to obtain the paper in advance.
