Over a week ago i bought a new Yamaha DTX452K drum kit. I use it with a new Ipad Pro 2017, bought last month (so all new, no attrition).
I use the DTX402 Touch and Rec'n'Share apps, however, yestday an issue arose with the Rec'n share feature that i cannot explain. I mean it was working fine until yesterday, but since then i am no longer able to hear the song i open for practice in my headphones (which are also new), but i hear the sound of the drums. i have tried with another set of headphones and it's still not working. So i can hear the sound of the drums in the headphones, but not the song i chose to practice over. The strange thing is that if i disconnect the iPad from the drum set, i can hear the song through the iPad's speakers.
I have also bought a new usb host cable, but the problem persists.
I also want to mention that the DTX402 Touch works just fine, so i am not sure what the issue could be.
