+Parameter To MIDI Mapping Properties
+These properties are used to:
+Describe a current set of mappings between MIDI messages and Parameter value setting
+Create a mapping between a parameter and a MIDI message through either:
+- explicitly adding (or removing) the mapping
+- telling the AU to hot-map the next MIDI message to a specified Parameter
+	The same MIDI Message can map to one or more parameters
+	One Parameter can be mapped from multiple MIDI messages
+
+	In general usage, these properties only apply to AU's that implement the MIDI API
+	AU Instruments (type=='aumu') and Music Effects (type == 'aumf')
+
+	These properties are used in the Global scope. The scope and element members of the structure describe
+	the scope and element of the parameter. In all usages, mScope, mElement and mParameterID must be
+	correctly specified.
+
+
+	* The AUParameterMIDIMapping Structure
+
+	Command				mStatus			mData1			
+	Note Off			0x8n			Note Num		
+	Note On				0x9n			Note Num		
+	Key Pressure		0xAn			Note Num		
+	Control Change		0xBn			ControllerID	
+	Patch Change		0xCn			Patch Num		
+	Channel Pressure	DxDn			0 (Unused)		
+	Pitch Bend			0xEn			0 (Unused)		
+
+	(where n is 0-0xF to correspond to MIDI channels 1-16)
+
+		Details:
+
+	In general MIDI Commands can be mapped to either a specific channel as specified in the mStatus bit.
+	If the kAUParameterMIDIMapping_AnyChannelFlag bit is set mStatus is a MIDI channel message, then the 
+	MIDI channel number in the status byte is ignored; the mapping is from the specified MIDI message on ANY channel.
+
+	For note commands (note on, note off, key pressure), the MIDI message can trigger either with just a specific
+	note number, or any note number if the kAUParameterMIDIMapping_AnyNoteFlag bit is set. In these instances, the
+	note number is used as the trigger value (for instance, a note message could be used to set the 
+											  cut off frequency of a filter).
+
+ The Properties:								
+
+	kAudioUnitProperty_AllParameterMIDIMappings							array of AUParameterMIDIMapping (read/write)
+	This property is used to both retreive and set the current mapping state between (some/many/all of) its parameters
+	and MIDI messages. When set, it should replace any previous mapped settings the AU had.
+
+	If this property is implemented by a non-MIDI capable AU (such as an 'aufx' type), then the property is
+	read only, and recommends a suggested set of mappings for the host to perform. In this case, it is the 
+	host's responsibility to map MIDI message to the AU parameters. As described previously, there are a set
+	of default mappings (see AudioToolbox/AUMIDIController.h) that the host can recommend to the user 
+	in this circumstance.
+
+	This property's size will be very dynamic, depending on the number of mappings currently in affect, so the 
+	caller should always get the size of the property first before retrieving it. The AU should return an error
+	if the caller doesn't provide enough space to return all of the current mappings.
+
+	kAudioUnitProperty_AddParameterMIDIMapping							array of AUParameterMIDIMapping (write only)
+	This property is used to Add mappings to the existing set of mappings the AU possesses. It does NOT replace
+	any existing mappings.
+
+	kAudioUnitProperty_RemoveParameterMIDIMapping						array of AUParameterMIDIMapping (write only)
+	This property is used to remove the specified mappings from the AU. If a mapping is specified that does not
+	currently exist in the AU, then it should just be ignored.
+
+	kAudioUnitProperty_HotMapParameterMIDIMapping								AUParameterMIDIMapping (read/write)
+	This property is used in two ways, determined by the value supplied by the caller.
+	(1) If a mapping struct is provided, then that struct provides *all* of the information that the AU should
+	use to map the parameter, *except* for the MIDI message. The AU should then listen for the next MIDI message
+	and associate that MIDI message with the supplied AUParameter mapping. When this MIDI message is received and
+	the mapping made, the AU should also issue a notification on this property 
+	(kAudioUnitProperty_HotMapParameterMIDIMapping) to indicate to the host that the mapping has been made. The host
+	can then retrieve the mapping that was made by getting the value of this property.
+
+	To avoid possible confusion, it is recommended that once the host has retrieved this mapping (if it is 
+	presenting a UI to describe the mappings for example), that it then clears the mapping state as described next.
+
+	Thus, the only time this property will return a valid value is when the AU has made a mapping. If the AU's mapping
+	state has been cleared (or it has not been asked to make a mapping), then the AU should return 
+	kAudioUnitErr_InvalidPropertyValue if the host tries to read this value.
+
+	(2) If the value passed in is NULL, then if the AU had a parameter that it was in the process of mapping, it
+	should disregard that (stop listening to the MIDI messages to create a mapping) and discard the partially 
+	mapped struct. If the value is NULL and the AU is not in the process of mapping, the AU can ignore the request.
+
+	At all times, the _AllMappings property will completely describe the current known state of the AU's mappings
+	of MIDI messages to parameters.
+*/
+
+
+/*
+	When mapping, it is recommended that LSB controllers are in general not mapped (ie. the controller range of 32 < 64)
+	as many host parsers will map 14 bit control values. If you know (or can present an option) that the host deals with
+	7 bit controllers only, then these controller ID's can be mapped of course.

+	This class wraps an AU (using the CAAudioUnit helper class) to use that AU for processing data
+	It can be used in a RealTime context (rendering data with RT constraints) or in an OffLine context
+	such as using an AU to process data that is stored in a file, and on which there are no
+	RT constraints to be imposed.
+	
+	Order of operations:
+	Create an instance
+	Establish an Input Callback
+	Initialize the AU to the audio formats and whether it is going to process in an offline or RT context
+	Preflight
+	
+	while (...)
+		Render  // based on your calling context
+	
+	PostProcess if needed (only in OL case)
+	
+	After any initialization, preflighting is required.
+	
+	Parameter Values on the AU should be set just before each call to Render. The sampleFrameOffsets
+	supplied when setting those values are an offset into that next render buffer's numFrames.
+	
+	RT vs OT is determined by whether the inputSampleCount is set during Initialization, thus
+	this class can move the AU between RT and OL contexts. If you are using an AU of type 'auol'
+	(Offline), then it cannot be used in a RT context.
+
+	The CAAUProcessor will only call your Input Callback for input when it needs valid input.
+	This input callback will contain a sample time that indicates where within your input
+	you should read data from, where after preflighting, the first output data produces is for 
+	the output sample count of zero.
+	
+	MaxFrames should be set before initialisation (or is also passed in to the Reinitialize API)
+		
+	If RT, then PostProcessing will *never* be required, nor will Render ever return an isDone value
+	If OL, then Render will at some point return isDone==true, and then also indicate if PostProcessing is required
+	
+	If using a Format Converter AU in offline context, then the only way for it to determine that you've finished
+	is for the Input callback to return an error. This means ultimately, that you'll have potentially longer output
+	than you should have. The only way to manage this is for the caller to know the relationship between 
+	input to output samples that will be required, and to call Render for just that amount of output samples
+	then return an error, so the tail and latency can be processed.
+	
+	Tail and Latency are *only* calculated at initialisation.. Some AU's may change these properties based on
+	either different presets or parameter settings... Ideally, this class should listen to those properties
+	and recalculate its values based on those changes.

+	// processing is done on the AU. However, because preflight is the first time that Rendering
+	// is called on an AU we can presume that this is outside the context of the processing that
+	// is occuring in the host application. To avoid taking page faults, priming cold memory, etc.
+	// when the AU *is* consequently used to render real data, the AU is prerolled and reset if this is the case.
+
+	// (2) Prime the AU's buffers with input data that preceeds the portion of audio you
+	// want to process. This amount of input data is equivalent to the tail time of the AU
+	// which expresses how long it takes for an sample on input to disappear from the output
+	// (Think of a delay or a reverb)
+	// So, by setting inProcessPreceedingTail to true, the preflight call will consume
+	// the tail time samples of input (which should be valid input BEFORE the data to be processed)
+	// So, your input proc here will HAVE to read samples from the preceeding input. The time
+	// stamps to your input proc in this case can be interpreted as 0 is the start of the preceeding data
+	// and you'll need to read up to the numSamples of tail time of the preceeding data.
+	// It discards the output results of the preflighting. If you don't have any previous data
+	// with which to prepare the AU, then you do NOT need to take this path and can do the step below.

+	// present a progress indicator. The Preflight call will do it all at once.
