Re: [AUDITORY] MIDI Drum Pads: Delay and temporal resolution
we will have a paper in this years SMC conference related to the
acquisition of tapping data using software implemented at INESC TEC in
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.

Dear Auditory List,
I am currently looking at purchasing a MIDI Drum Pad for
experimental research involving finger tapping. There appears to be
very little information regarding how much of a time delay there is
between the pads being tapped and the sound being produced (via
external MIDI devices or the drum pad's internal sequencer).
I'm looking to have the smallest time delay possible
(sub-millisecond would be ideal). Does anyone have any advice about
the best device to use and what kinds of time delays I should expect
from the device? Their unit of pulses per quarter note does not
appear to be very informative.
