Great piece of gear. For practicing is great it allows you to play music through the ae30 like it's the Bluetooth speaker and play along with the tracks through your headphones. Awesome connectivity to pro gear as well and lots of flexibility with sounds via the app. I'm still finding out new things. I would've liked for it to have an internal rechargeable battery and a better feeling low Eb and C key but for practice and show Synth it's hard to beat!
