Limits params can be use to limit a piano roll by setting start date / end date and lower pitch / higher pitch (see the C/C++ library documentation)
Options
- startDate:
date is expressed as a rational value
default value: “0/0” (start date is the score start date)
- endDate:
date is expressed as a rational value
default value: “0/0” (end date is the score end date)
- lowPitch:
a int value to control the lower pitch expressed in midi notation.
default value: -1 (score minimal pitch)
- highPitch:
a int value to control the higher pitch expressed in midi notation.
default value: -1 (score maximal pitch)
Using jQuery:
$.get('http://guido.server.org/XXX/pianoroll?startDate="2/4"&endDate="12/1"');
The layout options correspond to the LimitParams data structure.
