Ableton only plays sounds from the library but not in the workspace.
I can only get sounds to play from the library in Ableton, but when I move something into the workspace it remains mute.
I have the Novation midi keyboard hooked up to it, so it does most things automatically from the keyboard. I tried the keyboard with Arturia and it worked. So I know that it is something in the Ableton area. I have tried the ASIO audio format along with Direct X. I have them both synced to the speaker on my graphics card as my others stopped working, strangely.
Does anyone have any idea what the problem could be?
I think I understand where the confusion is. An .adv file is an instrument preset file. To use it in the Session view, after dragging it onto a MIDI track, you need to create a clip with notes that play the instrument, like in this screenshot:
I agree that it can be confusing that items in the Sounds section are previewed and presented as a small waveform when you click them in the Browser, but then need to be played with notes when you actually use them in the Session view.
I think what it is is that a driver is required for the MIDI. Which means that it has to be on ASIO in the audio settings with the driver selected. On Arturia it just picks the MIDI up so I figured it would be the same. However, with Garritan I was required to install the driver. But, for the Novation midi keyboard designed for Ableton, the MIDI has to be connected to the computer through an audio interface, because for some reason it will not read the driver through the USB connection as Garritan does.

This is QT5. Its on an embedded Yocto system, with QT drawing to the framebuffer, no X11. The problem is this. I want to play a video using gstreamer. So, I tried to launch gstreamer with gst-launch-1.0 linked to a touch event in QT. Problem is, it flickers as QT also tries to render frames.
Next, we tried Q media player. However, this proprietary gstreamer doesn't support playbin, so, I went into QGstreamerPlayerSession and modified the constructor to use gst_parse_launch to set up my pipeline instead of playbin.
This works, in that my video plays. However, there is still the same flickering! I tried to throw up a white rectangle before launching the video, but it still flickers.
How could I prevent QT from redrawing? Do I need an empty scene before playing the video? Or is there a function call to pause redrawing?
I could of course send a SIGSTOP to QT, play the video in an external application, then resume with a SIGCONT. That works, but is obviously a very inelegant and restrictive solution (I need the app to be processing in the background still as its controlling other things as well).
My HTC Vive is set up in a different room to my developer workstation. When developing for A-Frame, I understand I can: use my desktop monitor instead of a headset; use mouse dragging instead of motion controls; use WASD instead of room-scale tracking. However, what is the preferred way to simulate the tracked controllers?
For example, how can I move the cubes in this demo from my desktop: https://aframe.io/examples/showcase/tracked-controllers
This is not yet released, but we're working on tools to be able to record camera and controllers, output to a file, and then you can load it up any device and replay the camera and controller pose and events without needing a headset. Project is led by Diego:

This will become the common way to develop for VR without having to enter and re-enter VR to test each code change, and to do it on the go
I am attempting to record an app demo on the simulator, and want to use the Quicktime screen capture feature. However, I would like to hide the mouse during the capture.
Is this possible?
Doesn't seem to be a built in feature, so I am assuming I need to use some sort of plugin or hack.
Any suggestions?
QuickTime itself does not seem to offer this functionality therefore you have to resort to some other means to hide the cursor. On OSX there are some tools that allow this.
Cursourcerer is the first that springs to mind. However, as this really hides the cursor, it might not be ideal as you yourself will not be able to see what you are doing.
However, if you do not need to use QuickTime per se, it seems there are commercial screen recording solutions allowing this sort of thing such as Screenflow. I am not affiliated but the price seems reasonable and there is a demonstration of desired behavior here.
You don't record your app in your computer, but directly on your iPad or iPhone, connected to your Mac with a lightning cable. Then in Quicktime you select the "New movie recording" option (instead of "New screen recording"), then you will be able to select your iPad/iPhone as the "camera" and start recording your app running in your iOS device without any mouse pointer.

OBS can record your app window, and it ignores the cursor on the window.
Useful even if you are not a youtuber.

I use option+command+k (⌥+⌘+k) to show / hide. It works globally.
It's also useful to hide the mouse cursor when you do the control-scroll zoom trick to focus in on a video.
I already finished a simple QR Code apps by using ZBarCode library. I can scan the QR Code and capture the data back to my custom view.
I also can add a subview on Scanner view but that is just a layer and I would like to make a "auto focus" box like a red rectangle will blink when focused the QR Code and capture with SOUND.
It seems ZBarCode is not able to make an auto focus effect and capture with sound, is it something I missed or it's the limitation? If so, does any other QRCode library can do auto focus and capture with sound effect?
Thank you very much for any help!
The ZXing open source library can do that. It is available in an IOS flavor. http://code.google.com/p/zxing/
I'm not having an easy time making a workable mouse pointer interface on the Kindle with Qt (unofficial, of course). The fiveway joystick can't track more than one direction at a time (no diagonal moves), and the screen is too slow to update for good feedback.
I've got limited acceleration, but with the screen delay it's very frustrating to use. When you release the fiveway, the mouse will keep moving for 1-2 seconds... and it's not always a constant delay.
Given these limitations, I really need help from the application side. I need a method the mouse driver plugin could use to identify what the acceleration profile should be... so it can say slow down as it crosses a button. The app could help define regions where different acceleration made sense (start with single pixel shifts in a drawing area, but start at 10 or so for dialog dead space). More simply, the application should be able to tell the mouse pointer to transition from cursor to keypad mode, etc.
However, I can enumerate the mouse drivers, but I don't seem to get driver names. They're not QObjects, so there's no qobject_cast. How can I identify them as mine, and safe to cast to? I can force a cast, but that seems pretty lame.
Do I just assume the plugins are mine and cast them?
I'd like some simple signal/slot way to wire this up.
UPDATE
Maybe the plugins can notify the app somehow. Maybe using QApplication::topLevelWidgets(), trying qobject_cast looking for the QMainWindow... then sending it a custom signal with the plugin's internal QObject-based signal handler class? Then the app could turn around and set up the connections it actually wanted to deal with. I'll try it tonight or tomorrow.
Why don't you implement right as "tab" and left as "shift+tab". That way, you can move the focus around. Now, just center the pointer over the active area of the widget with focus (think checkboxes, they need the pointer over the box, not the center). I expect the user to be more interested in this and actually having a pointer to mover around in an environment where it is down right impossbile to use.
