Just imagine... Anytime, Anywhere, The Power of sound effects at your fingertips! The βsoundβ 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 four pages for a total of 48sounds! You can transfer your own wave, aiff, mp3, or m4a files to this iPhone app via iTunes and set it to your own selected sound button. Thatβs 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: βOne shotβ = only once. +++ βLoopβ = playing a phrase repeatedly. +++ βGateβ = 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. 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 βSound Syncβ 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,β 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. The Sound Sync series will be available from the middle of February, 2011. Your shows will never SOUND the same again! == iPod Touch support of the fourth generation.
