TRAX is the last and only app you will need this year if you: Play gigs in your local pub, provide music for your local church or anywhere on stage. Get rid of all those single feature apps and consolidate into one fully featured backing and split tracks app.

TRAX enables you to navigate anywhere within a song in a live environment with the simple touch of a button. Load in your song and place markers for the different sections of your song and you are ready to go.

TRAX is also perfect for teachers and students wanting to practice to a backing track as it enables a musician to repeat any section of a song as many times as they like.

As a drummer, the developer Marc Castles grew frustrated with other apps that are too limited and don't work well in live environments. Therefore he set out to create TRAX and is always improving it so that TRAX continues to be the best live backing tracks solution available.

Currently TRAX is available for less than $20 and offering a 100% money back guarantee. You’ve got nothing to lose from trying this out. We don’t believe in hiding in app purchases therefore you get the full product from a single payment.

This is hands down the best backing tracks app I’ve used

Really easy, intuitive and integrated. Perfect app 5/5

Plan on using this App for live gig performance. Used midi tracks for years, needed to update.
Once over a few operational issues e.g. unlocking the padlock which allowed the green lines to align text tabs, getting the set lists in went well.
Impressed with some feedback from the provider so that got me up and running.
An issue I have had is how to get back to the start of a song mid track. There is probably a trick to it but I have not received a reply yet. The App froze a couple of times but I think that was because I was asking it to do too much. No problem in playback at this stage. With a couple of queries clarified I would rate it 5 stars.

Fantastic music app!

TRAX is an easy to use app that allows you to play along to backing tracks or other music live. It is fun to use and I particularly appreciate the big cue buttons that allow you to individually label the sections of your song. There is no limits to the amount of cues you can include in your track. I would highly recommend TRAX to anyone looking for an easy to use app for rehearsing or queuing sections of the song in a live setting.
