The initialisation sequence is fairly complex. First a lock is acquired
so that a condition can be used to signal the end of the init process.
Then a sysex is sent to the device. The response to the sysex
is handled by a switch in handle_midi_sysex which calls one of the
other methods.
However, windows DAWs ignore the documented init sequence and so we
do too. Thanks to Essox for helping with this.
So we use the version firmware to figure out what device is on
the other end of the cable.
