Clock drops after fill message from MC6 Pro to Patterning (iOS)

Hi all–

I just picked up the latest version of the iOS drum app Patterning (3), and have managed to send clock out using the BT-01 wireless bluetooth dongle, sending the sync to a Boomerang III.

It works, but if I send a cc message to toggle on the fill function, the sync drops.

It doesn’t happen if I trigger the fill manually, by touching the iPad, so it must be the MC6 Pro.

Any clues as to how I can stop the sync from dropping?

Edit: I changed the switch from press and release to a toggle press–and discovered something strange.

The clock becomes disengaged while a fill pattern is played on the app!

So the bug is in Patterning, and not the MC6 Pro.

I will send a message to Olympia Noise Co and see what they have to report, then report back.

More edit—Ben has replied about the bug and is investigating.
