// -- Driver Design Rationale FFG 6/27/2013 --
//
// The AM16 was originally designed for use by musicians rather than
// broadcasters (it has a port for a foot pedal, for crying out loud!).
// Thus, it assumes that crosspoint changes are applied in batches
// ('patches' in MIDI parlance), necessitating a surprisingly complex
// procedure to change a single crosspoint without disturbing any of
// the others. The approach this driver takes is as follows:
//
// 1) Request a copy of the crosspoint map for the patch defined by
// AM16_PATCH_NUMBER from the AM16.
// 2) If we don't get the crosspoint map after waiting AM16_TIMEOUT_INTERVAL
// milliseconds, abort the operation (this to guard against unplugged
// MIDI cables and such).
// 3) Change the requested crosspoints on the map, then use it to update
// patches AM16_PATCH_NUMBER and AM16_PATCH_NUMBER+1 on the AM16.
// 4) Change the current patch on the AM16 to AM16_PATCH_NUMBER+1 and then
// immediately back to AM16_PATCH_NUMBER. (This bit of goofiness is
// required because the AM16 will not apply changes to a patch to
// the actual crosspoints while that patch is active.)
