Terms Launchd - clip gate mode?

I have clips in live set to gate mode. They behave as expected when triggered with the mouse - clicking down starts the clip, up stops the clip. When triggering the clips with Launchd, the clip plays completely through when a monome pad is pressed and released, rather than the clip stopping when the pad is released. This is the behavior one would expect if the clip was in trigger mode. Am I doing something wrong, or is this the expected behavior with Launchd?
