Practicing counterpoint is difficult if student cannot show exercise to a teacher to find mistakes. Even when working with a teacher, waiting several days until teacher can check exercise slows down education.
This is why we created Artinfuser Counterpoint site where everyone can upload counterpoint exercises and get their automatic analysis. I hope that it will help students that have limited or no access to teacher or need to find major mistakes in their exercises at once:
Just export your counterpoint exercise from your notation software into uncompressed MusicXML format, upload to the site and click "Process" - you will see PDF file with results. You will also get an MP3 with exercise being played by realistic virtual instruments.
I also attach an example of counterpoint exercise analysis.
