diyAudio Forums Archive > Top > Other Stuff > Electronics and Parts Soundcard Foot Controller - Click HERE for Original Thread JayZ I'd like to build a foor controller that processes its signal through one of the channels of a stereo soundcard (eg. Soundblaster). Has anyone tried this with success? admir Hi, Soundcards aren't capable of sampling DC, so how do you interface a potentiometer and measure it's value? Maybe with some software, generating kHz-range signal on one channel, while recording through foot pedal potentiometer to other... Just a thought ;)
