Thanks, nativevs. I’ll have a go at resubmitting it as it’s now been about a week since I sent it.
A month behind sadly has not been my own experience of the instrument submission process. Clearly mine was not up to pianobook standard. I sent it around the beginning of the year then resubmitted it about a month later. That’s OK though; it works for me and I use it on my projects. I’m happy to keep it to myself but this does mean I won’t be spending valuable composition time creating any more.
