Connecting an external pedal Controlling the knobs using an expression pedal (EXP FUNCTION) You can control the settings of the [LEVEL], [TIME] and [FEEDBACK] knobs with an expression pedal (such as a Roland EV-5, sold separately) that you’ve connected to the CTL/EXP jack. The factory setting is the value of the [LEVEL] knob.
Controlling this unit from an external MIDI device The SDE-3 delay time can be played back in sync with an external device when this unit receives a timing clock from an external MIDI device. Using timing clocks to synchronize with an external MIDI device When a timing clock (F8H) is received, the SDE-3 synchronizes with the tempo of the external device.
