On MF3, the docked iPad would periodically disconnect/reconnect the control surfaces. The recording on the docked iPad appeared to be intact however.
On MF4 the situation appears to have gotten worse. After several disconnect/reconnects, the iPad control froze completely (red dot in center of gear icon) and did not come back. The recording appeared to continue, however I have several loud glitches in the audio track, as well as several blocks of load fully-clipped static.
