Indeed, there is a bug in there. The code inside a loop is not using the correct variable. I am correcting this for the next version.
The exporting by wires is a bit of a hack currently. It simply mutes the machines that are outputing to the master, except for the one in the wire that is being recorded.
This might not fully work in a few scenarios (like a machine going directly to the master but also to an effect before the master).
Ideally, we should be telling the Master machine to give us the audio of a wire without the final mix. It shouldn't be too complicated, so if I have time, i might do it too.
