This has just saved me an ungodly amount of time! Seems to produce very few errors when working from nice clean pdf files. I've only picked up one error in 5 pages so far! These were scored for piano and flute, with the flute parts being for beginners and the piano at around intermediate level, so not super complex but also not the simplest thing I could give it. This will save me a tonne of time transposing parts for different instruments, and I'm interested to see how well it handles more complex scores too. Understandably a couple of errors when I fed it a photo of a 1-page piano score (beginner music, nothing complex!) in jpg format, but still did a good job on that overall, and still heaps quicker to fix those errors than it would have been to manually notate it myself. It didn't pick up anything at all from a photo in png format even though it was similar quality (to human eyes) to the jpg, but that's not an issue for me.
