How do you listen to it?
The Nebulophone has a 1/4″ mono output designed to be plugged it into any mixer, amp, USB interface, etc. Headphones will work but are not recommended.

Are the keys touch sensitive?
The alligator clip must be used to trigger the keys. You can also wire the key pads to switches as some makers have done.

Does my unit have the upgrade?
If you bought it after mid-2011 then yes!
