M4L Javascript "Get all devices" with callback:- Code check please!

    Feb 23 2014 | 1:29 pm
    Hi there,
    I've been learning javascript so I can get a list of all the devices in live through each track and through each of the first chains in a rack. I've looked at examples on the forum and it's taken me a while to get to where I am now but a few pointers would be great!
    I seem to be getting quite a few errors with "pushcontextframe/popcontextframe".
    Thanks in advance!
