// -- 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.)
|
