[Double post] Cubasis glitch, stops and starts

Hi I am using Cubasis connected to a motif rack via a Yamaha UD-BT01 bluetooth midi device.

I am using some midi tracks saved as projects in a live setting

The playback is not smooth ie I am getting glitches, stops and starts of tracks

I am using Cubasis 2 on an Ipad air 1

I originally suspected it was the Bluetooth device but have also experienced these issue using included instruments.

Any help would be greatly appreciated.

Thanks
