Having problems with midi connection to korg ec350

Using Bluetooth midi between Korg piano and beatmaker/iPad. Midi data comes through to beatmaker but at very low note velocity (not an issue with other apps as note velocity comes through at levels set on my Korg). Midi out does not seem to get back to trigger my Korg at all. Use midi set up to set all out put channels the same as input and a sequence does not trigger any sound on my Korg. Thx for any help!
