How to Modify this script to allow endless MIDI Rotary Knob to be able to also scroll up and down with one knob?

Hi @Reuven_Amiel,

Unfortunately I don't have any MIDI Rotary Knob's to test this out, however here is some information that may help.

A lot of MIDI controllers have an increment/decrement mode. In this mode, a controller continuously emits a value of 65 for every clockwise change (to the right) and a value of 63 for every counterclockwise change (to the left).

Based off this, you should be able to make an if else statement to trigger a + or - delta value to the mouse scroll.

This is untested, but you should be able to read the MIDI trigger event information by adding the following line of code to the script that has your rotary knob assigned.

const midiEventValue = event.trigger.midiBytes[0];

log(midiEventValue);

if (midiEventValue === 65) {
    log("MIDI rotary encoder was turned clockwise (to the right)");
} else if (midiEventValue === 63) {
    log("MIDI rotary encoder was turned anti-clockwise (to the left)");
}

If this doesn't work or give you the information you need let me know and I'll see if I can get my hands on a rotary controller.

Hi...

I tried it is not working... and yes I set the knob to give me a continues 63 value anti-clockwise and 65 Clockwise

this is the error soundflow reports:

20.08.2022 01:12:46.91 [Backend]: JavaScript error with InnerException: null
!! Command Error: Scroll Up Copy [user:ckjdi4ajl000anw10igxo5qwv:cl6y0pld90001ui10pyejz9gy]:
ReferenceError: midiEventValue is not defined
(Scroll Up Copy line 1)

this works:

sf.mouse.scroll({
    delta: +1,
    unit: 'Line',
});

But if you move left or right goes always up obviously as De1ta: +1 and there is not any values that separates from going left or right .

The idea is to set a part where as you said when MIDI is 65 scrolls delta +1 (up) Unit Line
and when MIDI is 63 Scrolls delta -1 (Down)

I am using to test this the Behringer BRC2000 that is very Flexible
You have 2 Values for increment and decrement that can be each from 0 to 127
I set the Knobs like this:
Type: CC Ch:1 Value1: 63 Value2: 65 Mode: Relative 1

We can set the Value 1 and 2 any way...most common are 63 and 65 and 1 and 127.
What is very important is to be able to change the delta value as this allows you to set the sensitivity of the knob.

Thank you so much and hope you can help with this.
