How do I delete Input Machines?

Hi,
How do i delete Input Machines?
I mean when I have over written an Input Machine with perhaps a Midimachine it stays active ( as shown in Tarekits Tricks “Using an Input and MIDI Machine on the same track”) how can i deactivate it.

Thanks

Overwrite it again with a synth or sample machine and trig it … should do the trick.
