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 Google+ 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.
