Timing Glitch while playing OP-Z and the loading IOS companion app

While I’m playing the OP-Z independently of the iOS app and then loading the iOS app the audio glitches in timing. Is there a way around this because during performances I like to load other iOS synthesizer apps while playing the OP-Z and using its companion app? I just have sync issues when I engage the app while the OP-Z is playing a sequence.
