First, I've found that if you use a shorter A/B usb cable for firmware updates and connecting to the iconfig software with a laptop or ipad it will connect to iconfig after multiple unplugging and plugging the usb cable back in to do firmware updates, longer cables don't work or will not connect!
Second, I've had issues when playing my 88 note keyboard where the keyboard looses connection to the iconnect and I have to turn off the keyboard and turn it back on to get sound again which I had in a discussion about disconnects on this forum before. Did not get any kind of answer or resolution. Longer A/B usb cables disconnected more frequently than shorted A/B usb cables.
Third, what would I change in my AUM app on my ipad to stop the sound from freezing, would it be Sample Rate which is at 44100hz, Buffer Size which is at 1024 or turn high quality on or is there another setting somewhere that I can change to stop the sound from freezing, it only does it for a split second once in a while when playing a lot of notes.
Maybe the buffer fills up causing it.
