Analyser Bug

Postby Tepeix » Sat Dec 03, 2022 12:55 am

Just find this strange bug with the analyser in 3.6.

Let's say i have a filter. I want to make a visual of the frequency curve while i use this filter.
So i make a copy of my filter, feed it with the same control knobs and use an analyser with the copy.

But this bypass the first code filter.. Just because the green control value are connected to the same code..

Edit : Maybe the example will seams to work, when all code restart it take the good value.
But if the controls are changed it will keep the same sound..

I find a fix. Using a sample and hold and a tick to transmit the controls seams to works.
But to be sure, i add a trigger pulse that delay the tick coming from the knobs to update the analyser.

Maybe the graph prim could also be used instead of the analyser, but needing to build some code to use it with an impulse..
