This is video 2 of a 7 part series — El Capistan Sound on Sound looping tips. This video goes over Loop Speeds.
El Capistan gives you the choice of two tape speeds. Turn the Time knob to the left of 12:00 for normal speed, turn it to the right for double speed. You get 20 seconds of looping time in normal speed, and 10 seconds in double speed. Like an actual tape machine, double speed gives you a higher fidelity recording.
