209 The intended order of events is:
211 - each surface sends a device query message
212 - devices respond with either MCP or LCP response (sysex in both
214 - sysex message causes Surface::turn_it_on() which tells the
215 MCP object that the surface is ready, and sets up strip
216 displays and binds faders and buttons for that surface
218 In the case of LCP, where this is a handshake process that could
219 fail, the response process to the initial sysex after a device query
220 will mark the surface inactive, which won't shut anything down
221 but will stop any writes to the device.
223 Note: there are no known cases of the handshake process failing.
