I use iTunes as my master library, with a number of crates created in Scratch (as I have used this for some years) I have been using the Xone DX for a few months, and if i load a long track, for example 196 minutes of where this track play fine in Itunes, on one player it appears to be OK, if I load all 4 players I get a pop up box stating that Itch has stopped working, and then it closes. The tracks are up to and in excess of 60MB (long mixes)

Is there a file size limit on Itch, as it just crashes constantly?

Standard "single" tracks I import into iTunes as WAV files, where an example would be a length of 3.30 seconds and a file size of 34MB

For your reference I am using a HP Probook 4720s with a 500 gb hard drive and 8gb of RAM. My library is 200gb with 28000 tracks.
