Lightroom 3 plugin for MIDI controllers
This plugin allows you to adjust photo develop settings using MIDI
continuous controller knobs or faders.
Unzip package to your home directory, giving you with this readme.txt
and Knobroom.lrplugin directory.
Ensure that your MIDI controller is connected, as the installation will
immediately open the device.
Start Lightroom 3, and open Plugin Manager from File menu. Click “Add”
and navigate to folder where the Knobroom.lrplugin is located. Select
Knobroom.lrplugin and click “Add Plug-in”.
Knobroom should immediately start and present you with a device
selection list. Select your MIDI device and the channel it is
listening. The channel is used for reprogramming device settings when
changes are made in Lightroom or the selected photo changes. Knobroom
always listens to all MIDI In channels.
You can assign MIDI CC numbers to Lightroom develop sliders using
File/Plug-In Extras/Knobroom/Assign Controls menu item. Selecting a
preset changes all settings at once, or you can modify each setting
You can either uninstall from Lightroom’s Plugin Manager, or if you run
into any sort of problems when starting Lightroom, you can just rename
or remove Knobroom.lrplugin directory when Lightroom is not running.
Version 0.1.4 (public alpha release)
– This is alpha release and it is not yet recommended for production
usage. The version will expire by December 31, 2010.
– MIDI input is shown on every Lightroom start. This is to remind you
that Knobroom is running. MIDI input selection from File / Plugin
Extras does not work properly.
– If MIDI devices are not connected when Knobroom starts, the device
list is not properly updated later on.
– Sometimes, when photo is deleted, Knobroom stops working, and reports
with “nil” error message.
– Setting white balance does not work for JPEG images, or if RAW image
is not set to Custom white balance.
– Lightroom plugin spawns a separate server process for handling MIDI
input. The process is connected to Lightroom using TCP socket 56627.
If you are using special firewall software, you might need to open this
port manually or be prompted to accept connections.
