How can I access the individual notes played within an “On Notevent callback”? I want to treat “m” as an array such that I can discern the chord, address the individual notes and expand the chord. EG: I have a basic C7 chord (C4-E4-G4-Bb4) coming in from a digital accordion and I want to rearrange it to an open piano chord (C3-C73-.G4-Bb4-D5-G5).

In the “On NoteEvent” or “On NoteoffEvent” I want to turn off/on the boolean for “MIDI Block noteon” in the midi block. … if not, can I turn on/off the note block filter boolean in the MIDI Filter? I just can’t find the GPscript function to do this.

For my understanding: You want to enable/disable the option in the MIDI In Block by pressing a note on your controller?
Try this as an example, a Widget controls the Note On property
In your case youw would do that in the on NoteOnEvent or on NoteOffEvent

On WidgetValueChanged(newValue : double) from KNOB
SetParameter(MIN, 288, newValue)

With this script you can build an array where all played Note Numbers are marked.
Now you can manipulate this array and at the end send Note Messages,
BUT: As the callback is executed for each played note - when is the right time to manipulate the array?
var nn : Integer [127]
MIN : MidiInBlock
on NoteOnEvent (m : NoteMessage) from MIN
nn[GetNoteNumber(m)] = 1
SendNow(MIN, m)
end
on NoteOffEvent (m : NoteMessage) from MIN
nn[GetNoteNumber(m)] = 0
SendNow(MIN, m)
end

Thanks, this (SetParameter(MIN, 288, newValue)) is great! However, where do I find the menaing of “288”. Also, I think the “New/Value” I send should be a boolean?
Take a look at the screenshot,
when you click on a gui element you see the parameter number in the top of the window.
the newValue is a number, the properties accept only numbers as I know.
The parameter values of any plugin are float (double in GPScript) ranging from 0.0 to 1.0. So, the typical off/on values are respectively 0.0 and 1.0.

Thanks, Paul. I will play with this code this evening … this should do the trick 
Your solution : "SetParameter(MIN, 288, newValue): works great! However, where does it say in the GP documentation the “288” is the “Note On property”?
If I say, “SetParameter(MIN, 1, newValue)”, it turns on channel 2 and sets its output channel to 16. … but where is the reference to this?
The documentation does not say that 288 is note on, it says where you can see what parameter number a property has.
Each parameter goes from 0.0 to 1.0
So you have to calculate the right value to set a properties to the desired value.
It you should think about using widgets mapped to such properties and use variations.

Can you tell me why this script doesn’t work? I am trying to set the MaxNote value to 60. It is my understanding that the Maxnote parameter in the MIDIBlock has a value of 17.
Var
M1 : MidiInBlock
nMaxNote : Integer
nMaxNoteValue : Integer
On Activate
nMaxNote = 17
nMaxNoteValue = 60
Print ("Activate - Setting MAX Note to 60")
SetParameter(M1, nMaxNote, nMaxNotevalue)
End
on NoteEvent(m : NoteMessage) from M1
Print ("NoteEvent - setting Max note to 15")
SetParameter(M1, nMaxNote, 15)
end
Parameter values must always be between 0.0 and 1.0 so a value of 15 makes no sense.
For MIDI note 15, you need the value 0.1181102
Now before you panic and wonder where the hell that number came from, there is a function called MidiToParam that converts MIDI values (i.e, integers between 0 and 127) into the appropriate parameter value between 0.0 and 1.0
So the following will work for you
SetParameter(M1, nMaxNote, MidiToParam(15))
will do the job

By the way, if your goal is to set keyboard splits, it’s useful to define a function to make it easier to use those parameters. For example
Var
Foo : MidiInBlock
Function DefineSplit(keyboard : MidiInBlock, lowerNote : integer, upperNote : integer)
SetParameter(keyboard, 16, MidiToParam(lowerNote)) // 16 is parameter index for lower note
SetParameter(keyboard, 17, MidiToParam(upperNote)) // 17 is parameter index for upper note
End
Initialization
DefineSplit(Foo, C2, C3) // Create a split between C2 and C3
End
To declare a MidiInBlock , I would say for example "var M1 : MidiInBlock " where “M1” is the handle of the MidiInBlock. My question is: How do I declare a source block?
What do you mean by “source block”?
the handle is “Source2” and I want to do this: “SetPluginBypassed(Source2,1.0)”
I am getting this error: “Semantic error: Line 67, Col 27: Identifier not declared: Source2”
Ok, you miss this
var Source2 : PluginBlock
You have to declare this block
And then this should work:
SetPluginBypassed(Source2,true)
The 2nd parameter is a boolean and not a double.

Thank you. I didn’t know the type “PluginBlock” as it doesn’t seem to be defined in the online documentation!
However, now this statement “SetPluginBypassed(Source2,1.0)” is getting the following error:
“Semantic error: Line 68, Col 35: Types are not compatible”
Yes, that works using “true” … but isn’t the value “1.0” the same as true and “0.00” the same as “false”?
