Even though I have connected the plugKEY, audio is still coming from the iPhone,iPad or iPod touch. KORG app November 16, 2018 20:26 Follow Some applications will prevent audio playback to external devices. In that case, the plugKEY will be unable to play sound. Facebook Twitter LinkedIn Comments Raf Goems November 16, 2018 20:26 I am still unable to spot which applications are preventing my plugkey from lighting up. Sometimes it will light up and when playing it would stop working. This also happens when I leave the gear for a few minutes and my iPhone still has sufficient battery charge. This problem is really annoying as I sold my Cubase, an Edirol ua25 and all that I have just to completely get into iPhone and synth apps. I am now unable to enjoy the apps especially after having spent some good money. This is quite disappointing. Please Korg, help me find a solution for this problem.
