PASSIVE MIDI FOOT switch

[Matt] was looking into some software application that enables him to utilize his audio card as a means to manage analog audio devices. After seeing exactly how it worked, he got an concept to try to do the opposite.  He is sending a signal into his audio input, as well as piping it to a pice of MIDI software. The input he has selected is a foot switch. To produce the signal, he just needed to supply voltage while the switch was depressed. You can see above that he utilized a battery as well as a simple get in touch with switch to send the signal. He then piped it to a online MIDI port utilizing Maple online MIDI Cable. Unfortunately, this isn’t appropriate for knobs, however that may be next on his list.
