Awesome but need some advice

The synth is awesome, very cool sounds and very easy to understand. Finally found something to replace alchemy. I need some help though. I use this with GarageBand, and I can switch from GarageBand to sunrizer with the inter app option, but once it takes me to sunrizer the GarageBand box doesnt pop up for me to stop/play/record or switch back. Any suggestions?
