**S8 with foot pedal?** Hi all, I just got an S8, I start liking it. I’m wondering if i can use my Roland EV-5 Expression Pedal with it for effects. I’d like to use it to control the parameter of my reverb that’s in FX unit 1, knob2. How do I connect it to the S8 (midi in? jack to midi converter?) How to map it? Thx for the help! ---

If it sends a midi signal, you use a jack to usb converter , plug it on your computer, create a new midi device within traktor and map it to your liking. That said I never used a jack to usb converter so I don’t have a clue if the midi signal would be transferred through the converter (once again if there’s a midi signal coming out your model). ---

You would need something to convert the output of the pedal, probably a variable voltage into midi. This could be done with a custom built (think teensy / Arduino) or a ready made device like this [MIDI Solutions Pedal Controller; Continuous MIDI Data Generator](http://www.midisolutions.com/prodped.htm)
