QLC+ version 4.10.0

18.10.2015

This page is dedicated to the numerous functionalities introduced with version 4.10.0.
Here there are the most visible changes we've done since 4.9.1, but constant activities of bugfixing and performance improvements are always ongoing, to increase the stability and scalability of QLC+ on large installations.
The following functionalities are in random order (and not by importance) and the complete changelog can be found at the end of this page.

Footnote: to give the proper support for this version and future ones, in the last months I went through a number of expenses: Akai APC Mini (77€), Raspberry Pi official touchscreen (85€), RPi hardware kit (40€), a second hand iPad 4 LTE (250€) + camera Kit (20€).
So, every donation is very welcome to help the project and allow me to continue to purchase furher devices for tests and improvements. Thanks !


RGB Matrix blending



A new option has been added to the RGB Matrix editor, to select the so called "Blend mode".
There are 4 types of blending modes: Default (HTP), Mask, Additive, Subtractive.
The default blending is the one we've been using so far. The standard DMX HTP rules are applied when running a RGB Matrix over already running QLC+ Functions.
The other modes, instead, act on a sort of layering between running Functions, including running RGB Matrices. They basically work on the same concept of layer operations you can do with image manipulation softwares like Photoshop or Gimp.
These modes allow to obtain fancy results in a short time. For example applying a mask matrix to a Scene can manipulate the Scene colors or turn on/off your lights with a RGB Matrix pattern.
Note that a blending matrix started before other Functions will produce no effect, since it would try to manipulate black colors.
It is therefore suggested to do blending layering via Collections, to make sure your Functions are executed in the correct layering order.

I have uploaded an improved version of the project file used in the Video Tutorial #6 with some blending modes included. Get Tutorial_6_RGB_Matrices_v2.qxw here.


Virtual Console buttons custom feedbacks



This long awaited functionality is finally here !
It was mainly requested by the Akai APC users, but it has been implemented in a generic way so even other types of controllers might benefit from this.
Basically it is now possible to define a lower and an upper value to be sent back to an external controller. By default, as it has always been, on/off values are 0 and 255.
This is available on "buttons", where buttons are most of the Virtual Console widget controls enabled by on/off states, including widget presets.

Here's a screenshot of what you will find. In the example, the OFF state will light a APC Mini button to red and the ON state will light it to green.
Please refer to the MIDI plugin documentation or your controller user manual to learn which values you should set. Please remember that MIDI values are divided by 2, so a custom feedback value of 6 will be actually translated into MIDI value 3.


Virtual Console Speed Dial enhancements



Thanks to Giorgio Rebecchi and David Garyga, a whole lot of new features have been added to the Speed Dial widget.
By default, when creating a new Speed Dial widget, it will look like the previous QLC+ versions, for backward compatibility, but opening the configuration window will allow to enable these new features.
The only exception is the "Infinite" control, which has now become a Preset button (thus easier to hit if you're using a mouse)

  • Multiplier and divisor buttons. When enabled, 3 buttons will be displayed in the Speed Dial layout, allowing to multiply and divide the current time value by a factor that you can increase or decrease. There's also a reset button to return to the 1x factor, so to the original time value of the Dial.
  • Apply button. This is useful particularly when using multiple Dials in a Virtual Console. The apply button will immediately set the current time value of the Dial, so switching from a Dial to another won't force you to change the time at all.
  • Presets. Like what has been done on the Animation widget, a Speed Dial can now include a number of preset buttons at the bottom of its layout. This allow instant shortcuts to pre-defined time values. Presets can have a specific name and can be activated with an external controller.
In this area there is still a bit of margin of improvement, so in the future we might add a "Store" button to save the current time value into a new preset.


Virtual Console Cue List step fader



The Cue List widget side faders can now be turned into a single fader, controlling the current Cue List step.
This allows to "sweep" across cues with a single fader that can be assigned to an external controller.


Solo Frame sliders mixing



Thanks to David Garyga, a new option is now available on Solo Frames to allow the mix of Virtual Console sliders in playback mode.
When this option is enabled, sliders in playback mode are allowed to be enabled at the same time.
When moving a slider up, instead of instantly cancelling the other running sliders, it will fade them out at the same speed you are fading it up.
Here's an animated demonstration, showing the difference of behaviour with the option disabled and then enabled.


Virtual Console XY Pad enhancements



In addition to the standard usage of the XY Pad, two new usages have been added to cover even more live needs.
In the widget configuration page you will find a new page to add presets.
Presets can have a specific name, can be activated by an external controller and they can be of 3 types:
  • Position preset: define an absolute Pan/Tilt position for the fixtures currently added to the XY Pad (in the configuration window, Fixtures tab)
  • EFX preset: it is possible to start an existing EFX Function and control its position and size with 4 controls, defined in the General page.
    When a XY Pad working window is defined, the EFX will be resized and positioned into it.
    Please note that this mode is not suitable for EFX in relative mode or if you really want to use them, you are warned.
  • Scene preset: it is possible to start an existing Scene defining Pan/Tilt positions.
    When activating this type of preset, the XY Pad will switch into a relative mode. The blue cursor will move to the center of the pad, and the current working window will be hidden.
    Moving the pad cursor will add a relative offset to the current positions set by the running Scene
Please refer to the updated documentation to understand in details how these all new modes work.


Input/Output Plugins



  • DMX USB: a major "under the hood" rework has been carried out but Windows and Linux users should not notice any difference.
    OSX/Important: This version aims to partially resolve the super annoying problem of the Apple FTDI driver conflicting with QLC+.
    For those who don't know the story, here's a quick recap.
    With Mavericks (OSX 10.9), Apple had the genious idea to introduce a new driver called AppleUSBFTDI which started to take control of every FTDI-based device plugged into a Mac. As most of the DMX adapters use FTDI chips, this change broke most of the software DMX controllers, including QLC+. A solution was found later on, forcing everyone to disable the evil driver and restore the peace in the world.

    QLC+ 4.10.0 has now started to actually use the evil driver, since Apple doesn't seem to provide an alternative to us poor developers.
    Basically the 4.10.0 DMG bundle now delivers 2 drivers: a native Qt which actually uses the Apple driver, and the usual libFTDI that we've had before.
    Unfortunately, the Open DMX adapters don't work with the Apple driver, so you'll still need to disable it in order to make them work.
    On the other hand, all the DMX USB Pro adapters will work out of the box, without touching your operating system. (so if you disabled the Apple driver, just re-enable it)
    In the DMX USB plugin information box, you will see a text saying "Driver in use: ...". If you see "QtSerialPort" then you're using the Apple driver. If you see "libFTDI" then you need to make sure the Apple driver is disabled, otherwise QLC+ will not be able to produce any output.

  • MIDI: Program Change signals are now working on Windows and OSX too.
    In the Input Profile editor it is now possible to tell the MIDI plugin to send (or not) Note Off messages to an external controller. This is what makes the Akai APCMini to work.

  • ArtNet and OSC: it is now possible to enter an arbitrary output IP address, to work across different routed networks

  • E1.31: added unicast support and stream priority parameter

Raspberry Pi



There are also some exciting news for the QLC+ on the Raspberry Pi users.
In random order:

  • It is now possible to run QLC+ in "no GUI" mode, so the HDMI output will be free to be used as you prefer (e.g. video playback or other applications)
  • The official Raspberry Pi 7" touchscreen is now supported out of the box. Please keep in mind though that it has a poor resolution of just 800x480 pixels, so you might need to adjust your Virtual Console to fit into a small screen
  • 2 new plugins have been added to cover some typical aspects of the embedded world: UART and GPIO.
    The UART plugin in particular, adds the support for the BitWizard DMX interface.
    An in depth article is available in the QLC+ blog section of the forum.

Linux automated builds



Thanks to the help of Veljko Stankov, the QLC+ project can now count on 60 different Linux packages, addressing the combination of 4 things:

  • Distros: Arch, Fedora 21, Fedora 22, OpenSUSE 13.1, OpenSUSE 13.2, OpenSUSE Tumbleweed, Ubuntu 12.04, Ubuntu 14.04 and Ubuntu 15.04
  • Architectures: 32bit and 64bit
  • Released and GIT versions
  • Qt 4 and Qt 5
Please note that released builds are in release mode, while GIT builds are in debug mode.
