The arpeggiator will not function. KORG app May 07, 2018 05:33 Follow Please check whether the MIDI Clock Source is set up correctly. Facebook Twitter LinkedIn Google+ Comments Theodore Moll May 07, 2018 05:33 The answer is vague. Please give better instructions on what to check to make sure that "MIDI Clock Source is set up correctly". I have set my midi channels to "all"...still no arp. I've set midi sync to Int, Ext, Auto... Still nothing. I've tried native NanokeyStudio mode in settings....nothing. I've tried Easy and Advanced. Nothing... I've reset the ipad multiple times...nothing. I've turned off the nanokey.. nothing. I get sound to happen but it just mutes when I hit the arp button. It used to work but not anymore. What can I do?
