Just imagine... Anytime, Anywhere, The Power of sound effects at your fingertips! The “sound” of the magic, a door bell, crashing sounds, thunder, a knock on a door, Sound effects are necessary in many performing situations. Up until now, for a sound effect to work, it was necessary to push a button on the touch screen of the iPhone, and you were not easily able to play sounds that you set yourself. Now you can program up to 12 sounds on each of 8 pages for a total of 192sounds! You can transfer your own wave (16bit,44kHz)files to this iPhone app via iTunes and set it to your own selected sound button. That’s right, "Sound Sync" can set the playing of each sound effect, or piece of music, to the button of your choice. You also have 4 settings of how the sound effect, or music, will be played: “One shot” = only once. +++ “Loop” = playing a phrase repeatedly. +++ “Gate” = plays only while you hold down the button. +++ Trigger = Continues playing the effect one time even if you release the button. +++ Pause = Pauses the sound effect or music until you want it to resume playing. +++ Vol = Volume adjusts the balance of other sound effects and with your Back Ground Music. +++ Sequence = sequence switch And will be played in the order of the file name. Fade In = starts playing with fade-in, you can set the fade time up to 15 seconds. To stop the play in Fade Out = fade-out, you can set the fade time up to 15 seconds. Silent Zone = the head of the file I will make the time of the blank. I can be set similarly up to 15 seconds. With the combination of the above settings you can have full control over how all of your sound effects are played! === In addition to the free “Sound Sync” app we also sell the "Sound Sync Receiver" which plugs into your iPhone. This will enable you to control your sound effects wirelessly using either our "Sound Sync Table,” our "Sound Sync Switch," or a combination of both for perfectly timed sounds at any time in your show to enhance all of your routines. Sound effects will now match the performer's own timing perfectly, wirelessly, anytime, anywhere you want! Now there is no need to hold countless meetings with the sound operator. Your shows will never SOUND the same again! == iPod Touch support of the fourth generation.

Inertia Pro is a completely new forcing app that relies on a diabolical new principle. Inertia Pro lets you force *anything* on *any website*... whilst the spectator is looking at the phone. It’s built in to a web browser, allowing you to use it to force pretty much anything, such as: • An Instagram photo or video on ANY profile. • A specific item for sale on eBay. • Any Netflix movie. • A product from Amazon. • A line of text or single word on a news website. • Any photo from Google Images. • ...and so much more! (Note: The page used is completely genuine - this will work on ANY website the spectator chooses, and in ANY language!) “Marc is without doubt the single greatest mentalism app creator I know. From design to execution, his apps are absolutely flawless. Inertia Pro is a prime example of why I trust in his work so implicitly, it is jaw droppingly good and represents one of the most cutting-edge mentalism releases to date!” - Michael Murray Plus, with Inertia Pro's new Edit Mode (paid feature), you can now edit the text on any site to ensure your force is included. ALSO - Inertia Pro: Momentum (paid feature) now also lets you use Inertia Pro on a borrowed phone. With multiple pairing methods available and a redirect process, Momentum is an extra purchase within Inertia Pro that will let you perform the same effect using a borrowed phone. Furthermore: WikiTest Pro Tools users can even use further integrations between Inertia Pro: Momentum. If you have Xeno, you can use your own Xeno Sites with Inertia Pro, or use any of the public Xeno Sites available in the gallery. And... you can perform Inertia Pro with any Xeno Site remotely! This can all happen on the spectator's device, without you touching it. Perfect for Zoom shows or long-distance performances! The Jerx wrote this about Inertia Pro: “You know those phone forces where you would hold the phone upside down and have them scroll blindly and whatever picture or item they landed on would be forced (usually because their scrolling wasn’t doing anything)? Well, this app allows you to do that type of force face-up while the spectator looks at the phone. It’s so good and *feels* exactly like it should.” - Andy @ The Jerx --- Inertia Pro is for entertainment purposes only, designed for professional performers. This app does not provide true mind reading abilities or anything similar. Please get in touch to discuss TV or video performance rights.
