Pitch issues djm REC app

Sorry, I'm not sure I understand -- can you clarify what the problem is?

the recording was in a lower pitch than i was playing at Despite having both master tempo's on the recoding sounded a way lower in pitch than its suposed to be

I think you mean it's an issue of samplerate of recording vs. playback. If I have to guess, I'm going to assume it recorded at 48kHz and is playing back at 44.1, which would make sound it about 8% slower.

What gear did you use to record and where was the file being played-back from?

I recorded it through usb cable on 900nxs2 and 2 cdj tour players
