The editor I am using for parts of my project is Anvil Studio, and it adds a ton of meta-events to each track that is solely for Anvil Studio and not needed in the final file. Is there any publicly available Windows-based program that can easily and automatically remove this data?
I use Sekaiju to get rid of the extra stuff when I am done editing.

Load the file, then select Event View, then on the right-hand side, right click on "Sequencer Specific" to show only that data, then you can delete it. It's a little tricky to figure out where to click to select the stuff to delete at first. Click the boxes in the column under "Track" in the event window to select the events. If you click the numbered lines to the left, you'll get strange results. Once you have only "Sequencer Specific" showing, click the top item, hold SHIFT, click the bottom item, and press CTRL+DEL. Voila! No more Anvil Studio nonsense.
If you edit it again in Anvil Studio afterwards, you'll have to repeat the process.
Bamboozled! I thought this sounded familiar... I hate spammers. 😤 😤
