  • Wide Padder with TouchUp to avoid hesitation
  • Skip function of the playing clip and of the next one running
  • Fast load button to easly manage scene’s changes

SyncInside manages the two stereo files syncronised play (file 1: stereo backing tracks, file 2: click and/or timecode) or a single file (4 channel interleaved).

  1. Saw Jessie Ware playing Coachella with what seemed like a hired band. She was triggering clips on an ipad as the songs/sections went along. Wonder if this was the app she used as I’ve not seen any other apps like this.

  2. Absolutely NO !
    SyncInside stops at the end of every clip, it automatically queues up the next clip and waits your tap.
    SyncInside is the first app that routes 4 tracks to 4 output.

    1. I am new, I am attempting to integrate my wav files into SI I have accomplished the import through iTunes to SI app. That is as far as I get. How do I get the files into SI from ITunes. Can you send me a step by step process of getting files into SI? Or explain the file formatting process. Iam lost!!

  3. I take it all back. Syncinside is brilliant once you understand how it works – turns out I was the useless one – well at least the dumb one. Thanks also to Francesco for his patience in getting me to understand it all.

  4. Howdy! This is my 1st comment here so I just wanted to give a quick shout out and tell you I genuinely enjoy reading your articles.
    Can you suggest any other blogs/websites/forums that go
    over the same topics? Appreciate it!

  5. Will it work correctly with NI Traktor Audio 2 Interface? I there a way in the app to send the track to the mains and click to the cue mix?

  6. I really love the idea and want this work, but although i load stereo wav files into Syncinside, it seems to play everything in mono over the USB port? Is there some setting i am missing here? The L/R indicators on the app show separate L & R signals, but only mono is sent out.

  7. I am having problems with Sync Inside and Behringer is202 – can’t get click out of ipad headphone out, everything is assigned correctly., USB tracks play, associated click will not.

    1. Problem solved – problem was with iPad – had to do an iPad reboot to keep ipad headphone output from automatically muting. App works amazing – just did 5 shows in Texas – worked flawlessly with the Behringer. Complete stereo playback with no bleed, stereo click is also the way to go (I add shaker to help subdivide click). 5 star rating – brilliant and simple. And Francesco has benn great!

  8. Hi,
    Do you have control over where the click track starts in relation to the backing track? We need a two bar cue/count in click for the drummer to count the band in before the song starts. Is that possible? Or, would I have to insert two bars ‘silent’ at the beginning of the song track allowing the click to start first? Would be great to have control over that as I think it’s a necessity for live performances.
    Best regards,
    Terry Nattress
