m@3
|
11 yes) and <multiple> and <n> are integers: the clock runs for <n> time
|

12 units before a probed event where the time unit is a multiple of the

m@3

42 To use in a study:
|
|
m@0
|
43
|
|
m@4
|
44 1. put the relevant midi files in the directory specified by <midi
|
|
marcus@15
|
45 file directory>. When playing the clock, the program can be a little
|
|
marcus@15
|
46 fussy about the onsets and durations of the notes in the midi files
|
|
marcus@15
|
47 being exact integer multiples of each other.
|
|
m@0
|
48
|
|
m@7
|
49 2. edit pfilelist.txt and filelist.txt (also in <midi file directory>)
|
|
m@7
|
50 to contain the midi files played in the practice and main blocks
|
|
m@4
|
51 respectively: put one file on each line followed by a list of note
|
|
m@11
|
52 numbers to probe with the visual clock (e.g., 1 = the first note).
|
|
marcus@15
|
53 NB: only use a single space between filenames and note numbers;
|
|
marcus@15
|
54 also, the last line of these files must terminate with a newline.
|
|

|
55
|
|
marcus@15
|
56 3. create a set of instructions for the study in an html file.
|
|
m@0
|
57
|
|
marcus@15
|
58 The results are written to files in the specified directory which must
|
|
marcus@15
|
59 exist.
|

|
61 4. responses can be given either using the mouse or using the numeric
|
|
m@6
|
62 keys (except in the case of a scalelength of 2 where the keys 'q' and
|
|
m@6
|
63 'p' are used).
