Yeah so it is a weird problem indeed.  
I’m going to paint the scenario:

I’m in FL Studio  
I route out Scaler2 into Addictive Keys  
I record a chord progression  
I burn the MIDI from Scaler2 onto the Addictive Keys track  
(SO far so good)

Here’s where the issue arises:

I will sometimes make an adjustment to the project.  
Maybe I’ll add in an audio loop.  
Maybe I’ll duplicate an instance of addictive keys  
Maybe I’ll delete a track I no longer wish to use.

Regardless, as I then make this change: The pitch of whatever track that was connected to Scaler2 will now randomly change.

Like I mentioned earlier, maybe it isn’t Scaler2, but I think it’s worth looking into, because maybe Scaler2 is triggering something within FL Studio that causes it to do this.

I saw one of the forum submissions here that somebody was experiencing a random pitch change in logic ([Link to it here](https://forum.scalermusic.com/t/scaler-randomly-changing-pitch/13004))

Maybe it’s the same kind of problem that requires a similar solution?

[Here’s another upload of a video showing the problem happening, but in a different project.](https://www.dropbox.com/s/xfr2y6mq0oscfy7/MIDI%20Issues%20FL%20Studio%202024%20%28Another%20One%29.mp4?dl=0)

_Note that I submitted this video to the FL Studio team as an effort to get this issue resolved with them too. They’ve been unresponsive in the matter_

Strangely enough, this doesn’t tend to happen in Ableton (I also use that DAW)
