I purchased a Looptimus last week and absolutely love it. I went on your site and found the suggested expression pedals and settled on the Roland EV-5. I have calibrated the pedal (thanks to your handy youtube channel) and have midi mapped it accordingly (doing it just like Matt did it on the YouTube Video with the master fader). However, the pedal is acting just like the buttons on the looptimus do and either turning ON the master fader or turning it OFF. No fading like in the video, what am I doing wrong?
