Button or footswitch to start recording

Is there any type of UBS device to trigger a record on Nano? Some kind of GPI interface is also be good for me.
Thanks a lot

Unfortunately no such device exists. The best way to achieve this would be to have a button or switch trigger an RS232 or HTTP API command to start/stop recording commands. This would require some development on your end to achieve this, but we could certainly assist you with ensuring the correct command and syntax is used in your development
