Missing Note Offs

[MKS30]

v1.1.086

Using the 'Show Midi' utility, I can see there are no 'Note Off' being generated when playing Drones and Pads.

Note Off is only transmitted when turning Drone and Pad Off.

Motif 1 & 2 perform as expected.

Am I missing a setting?

Surely this is not expected behavior..

Thanks
