Blueboard Issues

Hello. I am using Dreamfoot to control the Korg iM1 app and its working beautifully. I have noticed, however that when switching progressions within a song, all notes cut out when using the Blueboard. This does not happen when tapping the screen, just with the foot controller. Also, is there a way to get the Blueboard pads to hold and release as the screen button does rather than just keeping the sustain button on? Thanks.
