Experiment 2

12 different tones were used (2 pitches × 3 dynamics × 2 touches):

			without KB (wo)			with KB (wi)
	Pitch	Dynamics	HV	mnKey (mm)	mxAcc (m/s/s)	HV	mnKey (mm)	mxAcc (m/s/s)
1	E7	soft	105	–7.65	9.64	105	–8.16	38.40
2	F7	soft	104	–6.00	15.45	104	–7.92	36.66
3	E7	medium	111	–6.04	17.41	111	–8.00	36.71
4	F7	medium	119	–6.55	15.76	119	–7.92	41.01
5	E7	loud	120	–7.96	24.35	120	–8.43	58.41
6	F7	loud	122	–5.88	15.58	122	–8.12	49.84
HV (hammer velocity) ranges from 0 (silent) to 255 (maximally loud); mnKey (minimum key position of the transformed range from 0 mm, key at rest, to –10 mm, key fully depressed); mxAcc (maximum key acceleration) when key impacts key-bottom.

24 Stimulus pairs are formed (2 Orders × 2 Identities × 3 Dynamics × 2 Pitches):

		Order:	Order 1	Order 2	Order 1	Order 2
		Identity:	Same		Different
	Pitch	Dynamics	wi/wo	wo/wi	wi/wi	wo/wo
1	E7	soft
2	F7	soft
3	E7	medium
4	F7	medium
5	E7	loud
6	F7	loud
