When
does it react?
BP2
does react to MIDI input provided that (1) it is in the appropriate format,
i.e. the message has been declared in the "Interaction" window
("-in.<filename>" file), and (2) both the "Interactive (use input
)"
and "Use MIDI in/ou
t"
buttons on the lower "Settings" dialo
g
are checked (see Fig.24).
The
status of these buttons is saved and loaded along with "-se.<filename
>"
settings files. Each time a project, grammar or data is loaded, their status
might therefore change. Also make sure that a file has been loaded to the
"Interaction" window, or load it manually if necessary: its name will be
inserted on top of the "Grammar" and "Data" windows, so that it may
automatically be loaded next time you start the project.
A
third condition for BP2 to react to MIDI input messages is that it has free
time. Messages are stacked into the MIDI input buffer waiting for BP2 to read
them, which it does as often as possible. A delay in the response may be
caused by the fact that BP2 was engaged on some more urgent task.
Apart
from launching scripts, many parameters controlling BP2's operation may be
directly modified via the MIDI input, as demonstrated below.
