more. If you want to pass the MIDI message anyway, a simple mouse click on the
“Killing field” allows this.
Translation to...
This field, which has the header text “->”, can be used to define a complex set of changes – it can be
used to create a conjunction. If you click into this field, a “+” sign appears, and the outgoing
parameter change fields (see below) disappear. In this mode, the incoming MIDI message is parsed,
but is not used to change a parameter; VSTHost merely remembers whether the last message of the
given type and channel would match the other criteria.
This result is then ANDed with the next line. Only if both lines' criteria are met, the incoming MIDI
message is translated into a parameter.
Note: you can set up as many ANDed lines as you like, but they have to be followed by a line which
finally determines which parameter is to be changed. If this final line is missing, all ANDed lines are
discarded when the setup is saved.
Outgoing Parameter Change
This side defines which of the PlugIn’s parameters is to be modified by the incoming MIDI message.
It consists of the following fields:
Parameter Here, you can select one of the PlugIn’s VST Parameters.
If *Learn* is selected, VSTHost uses the parameter from the Automation value
change that comes in; this allows you to select *Learn*, then switch to the
PlugIn’s Editor window, twiddle the desired knob there, and (provided this is an
From
To
automatable parameter) instantly have the corresponding parameter selected.
Here, you can select the value range that is sent to the PlugIn. To do so, the
incoming MIDI message’s value range is converted into a possible range of
0.000…1.000, which is then expanded into the value range given here.
If the range is reversed (i.e., To is lower than From), the output values are
reversed, too; i.e., by specifying a range of 1.000..0.000 here, an incoming value
of 0.1 would result in a parameter value of 0.9 sent to the PlugIn.
Parameter -> MIDI
Selecting this menu entry opens a window that allows the mapping of incoming VST Automation
parameter changes to outgoing MIDI messages for the PlugIn. Most contemporary PlugIns can handle
incoming and outgoing MIDI Controller messages in more or less sophisticated ways; for those that
cannot, this dialog and its companion above (“MIDI -> Parameter”) have been added.
