Additionally, with multi-track recorders like the 'R8' that support FS01, you can remotely control transport functions such as play/stop/rewind, as well as punch-in recording. Operation confirmed. *Please refrain from purchasing if you are sensitive to used items. *We strive for prompt responses, but please understand that the item may be sold on other sites before your purchase. #ZOOM #Zoom #Footswitch
