 The following command will create an Uxn-compatible rom from an [uxntal file](https://wiki.xxiivv.com/site/uxntal.html), point to a different .tal file in `/projects` to assemble a different rom.

 You can also use the emulator without graphics by using `uxncli`. You can find additional roms [here](https://sr.ht/~rabbits/uxn/sources).

+### I/O

+

+You can send events from Uxn to another application, or another instance of uxn, with the Unix pipe. For a companion application that translates notes data into midi, see the [shim](https://git.sr.ht/~rabbits/shim).
