This is Oscilloscope. Always synced to Ableton Live's tempo.
It also works as an external window.
Window if fully resizable, ESC for fullscreen.
Added possibility to overlay waveform from another device.
Simply drag another copy of the device to the second track. Come back to the original device and click on, then select your second device in the list if you have more than one instance and you are all set! Every device has its number.
Also added one more mode L+R where channels are summing.
Now the device works even if Live transport is stopped.
The first release of the device
