      2. Press the <Page Up> and <Page Down> buttons to speed up and slow down the loop, respectively.
        • NOTE: When using the <Page Down> button to slow the loop, if the button is pressed enough times to where the Forward Speed = 0, then the loop will stop playing. Pressing the <Page Up> button will reactivate the loop at a Forward Speed = 1.
