Unknown function 'get'

[danlash]

First of all, thank you for authoring this module! I've been using raw midi input and am excited to change to this. I don't know if something changed in Chataigne but the script produces errors and doesn't work for many use cases.

Reproduction:

1. New session
2. Add apc mini module
3. Select the device in parameters
4. Press a button on the device
5. See error in the Logger panel
