As NPC1 mentioned, its mouse warping. If you dont need it, you can disable it in the Renoise settings:
When you need mouse warping, you can enable the compatibility mode in the piano roll settings:

Mhn, its working fine for me. Do you have a screenshot or a demo song?

Iâm not sure what am I doing wrong here but I canât seem to preview notes when using this tool , no sound playing till I click on play .also I believe many of the options are not working for me as they are supposed to (like changing loop positions) Maybe there is a setting or something I should check?
For note preview, you need to enable the OSC server in the Renoise settings:
Or check here:
What options doesnât work for you?
Sorry for the late reply.
Thanks ! That solved all of the issues

I donât show this tool enough love tbh. But it was my first piano roll tool and if youâre used to the FL piano roll, then this is definitely the tool for you, even if youâre not, itâs mouse centric and great for editing after youâve recorded your notes. Highly recommended

Any chance we could get a keybind option for just the histogram or even just the histogram as a tool by itself? Iâd love to use it without having to open the pianoroll first

Yes, that should be possible. I had already planned to implement it. Iâll prioritize that and let you know once I have something for you to try out.

I have been working on major changes to the toolâs code for a while now, which is why I have also applied the code adjustment for the histogram to the current version from the Renoise Tool section. You can download it from Github:
You can now use the histogram via the context menu from the Pattern Editor or alternatively set a keyboard shortcut. It uses the note selection from the Pattern Editor, allowing you to determine which notes can be processed by the histogram. If no selection is made, all notes from the pattern will be used automatically. I tested it briefly, and everything should work fine. If you encounter any issues, let me know. This feature will also be included in the next official release.
