how to display the notes on the canvas?
There was a problem with the display of music on canvas. if there are examples of such mapping would you demonstrate or show a piece of code that is responsible for mapping.
Could you please give us more details about the issue your are facing?
You can check the behaviour you may have on our music webdemo:
Did you check our documentation about Music Cloud api?
Can you reset the code display the result on the canvas. And in what format you want to receive the result, SCORETREE or MUSICXML?
It is the same purpose for cloud Math and cloud Music, you can develop your own piece of code to manage the rendering, but today we don't provide such feature. About result format to choose, both can be used Scoretree or Music Xml, but again it will require some development efforts to achieve this.
