UR44 HANGING and STUCK Note with MIDI

Recently I bought the UR44 Audio Interface. To be working with.
System MACBOOK PRO
i5 2.5 GHz
16GB RAM
OS MOJAVE 10.14
&
IPAD IOS 12
AKAI EWI 4000S as an external midi controller.

The problem is with MIDI of UR44 when I connect with MAINSTAGE 3.4.2 or AUDIO MODELING (CAMELOT 1.1) or TRANSMIDIFIER the note stuck and hanging while playing. and malfunctioning, generate different types of CC# which I didn’t assign in the external midi controller.
Both the same problem with MACBOOK PRO and IPAD. In IPAD checked with AUDIO MODELING CAMELOT same ISSUE.
USB DRIVER ( USB Driver V2.0.3) UR44 Firmware Update V2.12 is installed.

Checked with other midi interfaces of M-AUDIO, ROLAND, PANDA AUDIO MIDI BEAM in both MACBOOK PRO and IPAD there are all fine working with the softwares I mentioned above.
