How to iterate a parameter using midi note on events (new user)

[dane.custance]

Hi there, I want to be able to iterate the rotation of an object by 45° each time a midi note is triggered. In simple terms, it looks like this.

The first midi note is triggered from 0°, the object rotates 45°, rests in this position and then the next time the midi note is triggered the midi note continues from its 45° position to 90° and so on until it reaches 360° repeating the cycle in 45° increments.

I have not been able to figure this out and would be grateful if anyone could share any approaches I could use to achieve this effect.

Thanks.

Hello ,
one way if you does not need animation is to use python like this

from math import radians
rot = script.parentElement.parent.parent.renderer.placement.rotation

rot.set(rot.get()+radians(45))

and trig the script with the midi note link

Another way is to use a link a a set trigger to like this to add the 45deg to the existing rotation
SetAddTrig.compo (98.9 KB)

( the offset value is in radian so 0.785398 is 45 deg )

Thanks for your support RBasile, ill need to learn python before I can get the most out of the scripting feature but ill try your method, and have good look at the example file you provided.
