Everything seems to work the way it should, although I haven't tried it with a device with multiple vibes.

Just a heads-up: I've updated this plugin with better reliability, a number of API improvements and a custom options menu. (And hopefully no new bugs.)
The API changed a bit from version 0.1, so I don't recommend upgrading it for existing projects, but if you make a new mod in the future please give it a spin and let me know what you think.
The main improvement is that you can now seamlessly transition between patterns and wait for them to complete in linear scene events. There's better multi-motor support too, so all patterns are now automatically retargeted for devices with fewer or more features.
