These recordings helped to determine if audio, video, or both audio and video feedback received while playing a simple, single-button MIDI instrument can effect how the participants play over a time period of 10 seconds.

The image below explains the shapes that appear in the visuals.

Participants played through a QuNeo MIDI pad controller, hooked up to a PC running Ableton Live 9 and Processing 2. Live recorded the MIDI signals sent from the QuNeo, while simultaneously forwarding the signals to a Processing sketch. (Live handled the audio while Processing created the visuals.) The audio played through stereo desktop monitors and visuals were displayed on an LCD screen.

All but one of the QuNeo's pads had been covered to make the instrument as easy to use as possible. This was also done with hopes of focusing the participant's attention toward their technique of playing.

• Conclusions

After the data had been gathered and analyzed, a few observations rose to the surface:

• Average button hits per person, per second was 7.3
• 88.6% of button hits were quick taps (i.e. the button was pressed for less than a quarter of a second)
• Only two of the observed participants held a button for more than one second
• Audio + Video Feedback participants had the most button hits out of the three groups, with a mean of 35.6
• Average velocity of button hits was 75.4
