MIDI keyboard range script?

[musictop]

Any help/link/suggestion on how to let users set keyboard range per sampler/synth?

thanx.

Do you mean allow the user to limit the range of playable keys? Or do you want to change the colour of the keys on the on-screen keyboard?

[musictop]

@d-healey to set/limit the range of playable keys.

thanx.

@musictop You just need an if statement in on note on.

if (Message.getNoteNumber() < lower_range || Message.getNoteNumber() > upper_range)
    Message.ignoreEvent(true);

You can set the lower/upper values from whatever controls you want on the ui.

@d-healey thank you so much David.

Hi guys,
I would like to make UI with 2 flexible split points (for tenor / soprano / piccolo instruments) and on first sight your bit of code is exactly what I was looking for.
It works great when I replace lower_range and upper_range with numbers, but when assigning a slider to set the ranges from the UI they become just on/off switches (range 0-1 switches at 0.5 ; 0-127 at 1).

Obviously I would like to set a value between 0 and 127 with a slider in the UI. Any Idea how to make that happen?

thanks!!

@meyerkeys Hi
You can set the slider ranges in the property editor of your sliders (0-127) (don't forget to set the stepSize to 1)

Then first solution:

• Create the slider's Script Reference in the onInit callback.
• Then in the noteOn callback, you can replace the lower_range variable with myLowRangeSlider.getValue()

Second solution:

• Keep the const var lower_range variable
• Create a callback for your slider in the onInit
• In the callback, place lower_range = value;

'cept it couldnt be

const var lower_range

it would need to be

var lower_range

@Lindon Oups sorry, you're right const shouldn't be here...

[meyerkeys]

Many thanks guys!

I wondered about "const" as well but I got it working with both versions.

Cheers!

@meyerkeys yes the first solution @ustk offered may well work but the second wont as:

lower_range = value;

means you are assigning a value to a constant - and that wont work. constants get set and can never be changed - theyre, huh, constant...:-)

[d.healey]

If the constant is an object you can change the object's contents.

const var foo = [1, 2, 3];

foo[1] = 10;

Console.print(foo[1]);

[meyerkeys]

Thank you guys for staying on this.
I kind of wondered about the const or const var thing anyway as David is using const var mostly in his great videos. Can't thank you enough for those btw.
So your last post clarifies again. Got it.

@meyerkeys You can find more information in the doc about the different variables in Hise
