the arguments of performance controls from MIDI
the same way notes can be "typed" from the MIDI keyboard, the arguments of
may be captured from a MIDI device. Suppose that you entered "C5 D5 F5 G5 C6
A#5 A5 G5" in the "Data" window. Select "Pick performance contro

Click the word "_pitchbend". The argument of "_pitchben
gets hilited. Now move the pitch bender. BP2 automatically converts in-coming
pitchbend messages to cent values (within the specified range) writing the
result as an argument of _pitchbend. Of course it is a good idea to play A5 or
G5 while you are moving the pitch bender, so that you can hear the effect.
process works if the pitch bender is sending messages to the specified channel.
Otherwise, click "_chan", move the bender, and let BP2 record the channel number.
Great, but if I release the bender the final value is always 0, isn't it? The
solution is to hit the space bar or click the mouse anywhere (outside the word
"_pitchbend"...) as soon as the desired position has been reached.
the same with modulation: click "_mo
and move the modulation bender while playing notes. You can adjust the
argument for "_ve
similarly: BP2 records velocities of in-coming NoteOn's.
volume, first click "_volumecontrol" and move the volume pedal to record its
number (most likely 7). Then click "_volume" and record the pedal position.

instruct BP2 that controller x is the one modifying volume or panoramic
respectively. Default arguments are 7 for volume and 10 for panoramic.
