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