MIDI Controllers
Vapor responds to MIDI continuous controller messages. You can use hardware MIDI controllers, such as MIDI
slider boxes or the knobs found on some MIDI keyboards, to adjust Vapor’s parameters.
Vapor has a simple “MIDI Learn” mode for assigning its controls to MIDI controllers. To assign a control to a
MIDI controller:
 First, hold down the SHIFT and CTRL keys on your PC’s keyboard, or SHIFT and CMD keys if you’re
using a Mac, and click once on the control. A white box will be drawn around the control to indicate
that it is ready to learn which MIDI controller it will be assigned to.
 Next, move the MIDI controller to send a continuous controller message—turn the knob, press the
button, move the slider, whatever is appropriate.
 The white square will disappear. Now the control will move when you manipulate the MIDI controller.
Vapor waits until it has received two consecutive continuous controller messages with the same controller
number before it makes an assignment. This filters out extraneous data sent by some MIDI controllers. If you
are assigning a button or switch on a MIDI controller, you may have to press or move the switch twice before
Vapor recognizes the controller and assigns it to the desired control.
To assign a different MIDI controller to a control, repeat the same procedure using a different controller.
To cancel MIDI Learn mode without assigning a controller, hold down the SHIFT and CTRL keys (SHIFT and
CMD keys on a Mac) and click in any empty area in Vapor’s window (i.e., don’t click on another control). The
white box will disappear.
To remove a MIDI controller assignment from a control, SHIFT and CTRL keys, (SHIFT and CMD keys on a
Mac) click on the control once so that the white box appears, then click again on the same control.
Vapor’s MIDI controller assignments apply to all presets and instances of Vapor, in all host applications that
you use. The MIDI assignments are stored in a special file on your hard drive. The contents of this file are
read when Vapor is loaded by your host. If you have two or more instances of Vapor in use at once, any MIDI
assignments you make will not be propagated to the other instances until the next time that your host loads
the plug-ins.
