Re: [AUDITORY] MIDI Drum Pads: Delay and temporal resolution

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.

Quoting Benjamin Schultz <benjamin.schultz@xxxxxxxxxxxxxx>:

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.

Kind regards,
