Mix Check is an iPhone app for Recording Engineers and Musicians.
It is a simple player for working with a small collection of tracks. Its Link Playback feature aims to make a/b-ing different mixes or recordings or reference material more straight foward.
You can reference songs in the Music app on your phone, or import them from other apps.
I made it as I got fed up for people emailing me roughs and not having reception on the train to keep listening to them - with this you can save them straight to Mix Check.
Songs carry on playing in the background and you can use your headphone remote or the Control Centre to skip tracks.
Im not a full-time App developer, I made this simply to make my life easier - as such, do let me know of any rough edges you find...
