# Sample trial similar to Wing, 1977, "Perturbations of auditory feedback
# delay and the timing of movement". This is a synchronization/continuation
# experiment in which the feedback on one continuation keystroke (only) is
# perturbed.  Pitches and sound levels do not precisely match the original
# experiment,, and I've made the tone lengths longer than 10 ms because it 
# sounds better on my tone generator.

# Other conditions would involve MSPB set to 350 and 650, base FEED_DVAL
# set to 15 instead of 25, and different delay and trigger values for
# triggers 2 and 3. Note that since you don't know exactly when the subject
# will start tapping, the available trigger types do not guarantee that
# the perturbation will occur precisely on the 11th "continuation response"
# as described by Wing.
