I recommend to anyone looking for a solid alternative/companion to your midi controllers. The editor is easier to use on the mac, but easy enough on mobile device. Soon enough it all started to make sense (midi). OSC mappings really don’t make any sense to me, yet.įor my midi hardware setup, I just put the time in comparing the preset layout parameters to my custom layout. The manual is very matter of fact and could really benefit from small tutorials/step but step. Could really use explaining the relationship between OSC and logic controller mappings. And as far as syncing with logic pro, it seems like 50% of the time, it just won’t work. It was a bit confusing to get started however. Super fun having four XY pads sent to filters and envelopes of my hardware synths. I just built a custom layout that is sent to my computer, and then back out via midi usb to my modular synthesizer. Pretty fantastic app once you get it set up. No longer making "capture attention" required was a HUGE improvement (made it possible to make surfable/strummable instrument designs), but it’d be even better if you could hit both controls at once when they overlap.

The first play of the game, safety Jessie Bates surprised Tannehill and pulled off an interception to set the tone, but plays like this showed why the Bengals made it so confusing. Three turnovers and this sack were at the forefront of an upset that sent the Bengals to the AFC Championship game. “Man, we had ( Titans QB Ryan) Tannehill back there just patting the ball the whole time like, ‘Where are my reads at?

Patience to let the blitz develop is imperative to success and they hit it with perfect timing. ![]() It only works because of the time on task with Wilson and Hubbard, in particular. They decided the first playoff game would be a perfect time to break it back out for a fresh look under pressure. The Bengals ran this earlier last season in Pittsburgh and got a sack and interception off Ben Roethlisberger. But it’s only possible because a player like Hubbard with a background as a linebacker, who can stand up on the edge, move inside or drop into coverage, brings versatility to fit this play. It’s simple and hardly a disguise as it is specifically meant to force all the extra communication. Then we got good players and get them one-on-ones and they win.” The play clock is running when all this is happening … There is a lot going on. That forces them to do something different. “Now it goes to three down, linebacker is mugged up look. “We are in a four-down look,” Anarumo said. He has to bring in the motion man when the clock is now down to eight seconds, all while adding one more adjustment to the running back. That’s a ton of communicating while a playoff crowd roars deep in his own end. ![]() Just that switch alone forces him to walk to the line, point out the move to his line and make the protection adjustments. The move unfolds with 19 seconds left on the play clock and quarterback Derek Carr surveying the field on third-and-4.

In addition, they may not work with your camera brand or model, so double-check this before you buy and install. These programs normally cost, even if it’s not a big amount. Once installed on your computer you just have to plug in your camera and run the program. Otherwise, you can download specific software. The only downside is that you’re sharing your image with a third party and you may not be comfortable doing this, understandably. Not every model is supported, but it’s worth trying. Some websites allow you to upload an image from your Canon camera, and the Exif data is pulled from it. The majority of Canon’s cameras don’t include the shutter actuation count in their Exif data, which is why it’s difficult to find. But some manufacturers, like Canon, don’t give it up that easily. Within this information, you can find the shutter count in most cases. Also, some programs like Photoshop and others from the Adobe Creative Cloud have this feature. There are many websites where you can upload your images in order to extract the Exif data. If you want to see this information, there are a few things you can do. This is done automatically by the camera. The Exif data will tell you the camera’s brand and model, the settings, the author, etc. This is the information recorded by the camera when an image is taken. In most brands, the camera’s shutter count is saved in the Exif data of the photo. this topic is different to shutter ‘speed’ – see here.) Or maybe you just want to check and compare it with others so that you can price it correctly if you’re considering selling it. Maybe you’ll find out that it’s time to upgrade your gear. You can use shutter actuations to diagnose your own equipment as well. For example, if you’re buying a second-hand camera and you’re indecisive between two, you can use this information to decide which one to get. It’s important to know the shutter count because it will let you know how much ‘life’ a camera has. The number of times a camera has fired is therefore counted by the shutter count. This operation can only happen so many times (the ‘maximum shutter actuation count’) in the lifespan of a camera because these pieces wear out. Most of the time the camera shutter movement happens in fractions of a second, putting the mechanism into a great amount of pressure. In the case of DSLR cameras, there’s also a mirror that needs to move out of the way for this to happen. These parts cover and uncover the sensor allowing the light to ‘imprint’ the image. This is because every time you shoot a photograph, there are a few pieces on your camera that go into motion. ![]() The camera’s shutter count (shutter actuation count) can be a useful way to gauge the longevity of your gear.

Nous concluons que la coherence du timbre definit une probabilite (et non des valeurs precises) des parametres d'une syllabe dans un contexte donne. Une experience de remplacement de syllabes avec modification de f0 confirme l'importance de la hauteur. Le critere principal pour la coherence d'un montage est que la syllabe introduite ait une hauteur proche de la syllabe remplacee, et que la prosodie de la phrase soit respectee. 23% des montages sont acceptes (50% des montages entre locuteurs de meme genre) donc une syllabe peut etre commune a differents locuteurs. Les sujets doivent indiquer s'ils entendent un montage ou une phrase prononcee par un seul locuteur. Dans la troisieme experience, nous remplacons, dans chaque phrase, une syllabe par les syllabes correspondantes des phrases d'autres locuteurs. Dans la deuxieme experience les sujets doivent juger selon des axes predefinis (age, genre) les phrases et les syllabes: les resultats montrent que les jugements pour la phrase entiere et pour des syllabes isolees peuvent differer, amenant la notion de timbre global (phrase) qui est compose d'un ensemble de timbres locaux (syllabes) pouvant varier beaucoup. La premiere experience etudie la comparaison holistique des phrases et des syllabes : les resultats montrent que les syllabes ne sont pas classees selon le locuteur, et que les criteres de classification sont differents pour les syllabes et les phrases. Nous en extrayons deux syllabes de meme contenu linguistique mais comportant differents accents toniques. Pour etudier la coherence, nous utilisons comme materiau une phrase (un chiffre italien lu de facon neutre) prononcee par 20 locuteurs. more A partir de la notion de timbre de la voix, definie comme ce qui caracterise un locuteur ou une elocution donnee, nous degageons la notion de coherence du timbre, c'est-a-dire, les limites que doivent respecter toutes les composantes d'une elocution pour qu'elle semble avoir ete prononcee par une seule personne reelle.

This is because there is less atmosphere pushing down on the air molecules and pressing them together.Īt 5,000 ft above sea level, the barometric pressure is 24.89 in. There are fewer oxygen molecules per volume of air in the mountains than at sea level. If you have ever gone hiking or skiing in the mountains you know that it is harder to breath. The table below, from, shows that increasing temperature doesn’t begin to make a significant change in the air density until it gets above 100º F. 0735 lbs/ft 3 which is 2% less than Standard Air density. At the temperature of 80º F, the air density is. To determine the impact of higher temperature on air density, this time we will keep the Standard Air conditions the same except we will increase temperature from 70º F to 80º F. Pilots know that when the temperature increases, the air is less dense and that it requires a greater distance to generate the lift required to take off. As the air temperature increases, the molecules in the air are excited by the additional energy and they move further apart. Increasing temperature causes most materials to expand. The graph below, from, shows that relative humidity doesn’t begin to have a significant impact on air density until the air temperature is above 40º C or 104º F. At 70º F, humidity changes have very little impact on air density. 074322 lbs/ft 3 which is 1% less than the Standard Air density. By how much though? If we keep the Standard Air conditions the same but we increase Relative Humidity from 0% to 100%, then the air density deceases to. We know that when humidity increases, the air gets less dense. The scientific explanation is that when humidity increases, water vapor molecules that have an atomic mass of 18 displace nitrogen and oxygen gas molecules that have atomic masses of 28 and 32, respectively. Aren’t wet things always heavier? I remember learning this fact when the TV Weatherperson said that decreasing barometric pressure often happens in advance of rain. I was amazed as a kid to learn that air gets lighter when humidity increases. But what if my customer’s location is not at sea level or they will be running the fans during the summer months when it is hot and humid? What Affects Air Density? In the first of this two-part article, I’ll discuss how changes to temperature, altitude and humidity from Standard Air conditions affect air density. 075 pounds per cubic foot at the conditions of 70º Fahrenheit, sea level barometric pressure of 29.92 inches of mercury, and 0% relative humidity.
