Tuning Notes in Rhythm

[GoogleCodeExporter]

De-tuning.  Having the ability to de-tune the probe tone.  I know MIDI offers a 
de-tuning option, and there are some versions of the task where it would be 
useful to detune some notes to see when that change is perceptible.  To do this 
we would just need a “hook” into the MIDI command for pitch changes.    
Experimentally we would then manipulate the tuning of the probe tone as a 
variable, specifying different levels for each trial.  
The idea is that we would then manipulate this as a parameter like with the 
offset values (i.e. an array of de-tune values to apply to the probe tone).  In 
the case where we had, say, two values of offsets and two values of probe tones 
then we would have four combinations for that block.

Changes made by r174

Property 'probeDetuneOffsets' has been added to allow a hook into detuning the 
probe tone. 
Values can be entered similarly to the way used for baseIOI offsets, namely 
comma delimited values. 

probeDetuneOffsets can accept integer values between -50 and 50, allowing up to 
a half semitone detune in either direction. 

Property 'offsetDegrees' changed to 'baseIOIoffsetDegrees', for clarity.

Requested changes as per correspondence:
See r177

-Renamed 'probeDetuneOffsets' to 'probeDetuneAmounts'
-Renamed 'baseIOIoffsetDegrees' back to 'offsetDegrees'

-Added ability to be able to detune arbitrarily far, not limited to -50 to 50 
cents. However this arbitrary detune is limited to the minimum and maximum 
pitches allowed by MIDI.

-Added property to label the first accuracy question for responses, called 
'accuracyResponseLabel'

Fixed error that made response checking only check baseIOI differences. New 
property added to specify what is being tested (timing or detune) called 
'experimentTestingType'. 

See r185
