If not already on the bucket-list, please add guitar palm muting to the list of requested techniques. Thanks!
When we come to add more support for guitar, we’ll certainly add this. The reason we don’t have it now is that (as far as I know, though please correct me if I’m wrong) it’s normally written with a line extending beyond it, and our playing techniques don’t yet have this capability (though it is of course planned).
True, I look forward to those lines as well! Thanks.
