See Music Issue with metronome and other
(See Music)
Unfortunately we do not know if or when See Music will be operational again. See Music uses MIT’s audio kit to hear and analyze a human being playing an instrument and to provide a report of the performance.
At this point we are forced to suspend support for See Music until the MIT updates the audio kit.

Some customers have trouble downloading large files because their internet connection is interrupted during the process. Also, some customers have a difficult time downloading to iPhone or iPad, either due to a weak internet connection and/or the amount of memory space available on their device.
We found most people have an easier time downloading and unzipping on a computer, then sending the PDF files to their iOS device. The easiest way to share files between mac devices is using AIR DROP.
If you have access to a computer, please download there. Make sure you have a reliable internet connection. Check to make sure you have enough memory space on your iOS device before sending the files via Air Drop.
