If you use some kind of LMS, there is a built in way to do this in just about all of them, including MusicFirst. But as far as actual device, we don't care. We only have three chromebooks available for kids to use if they don't have a device. Be aware that some students may not be able to record a large file on their device for a variety of reasons and thats when we ask them to grab a chromebook, or have them play for someone in class, etc.
