The front panel is divided into two main sections: SETUP (top half) and RUN (bottom half). The controls are grouped logically in each section, with some knobs having dual functions; they're placed in the middle, right on the double line.
THE SETUP SECTION
- SELECT STEP: Press the button to cycle through step one to eighth to get to the step you wish to edit. The current step is shown on the display.
- TUNE: Change the pitch on the selected step. Use the COARSE and FINE switch on the right to change the tuning mode. COARSE changes the pitch a semitone up and down, while FINE gives a smooth, gradual pitch change.
- PATTERN SAVE/LOAD: These two pushbuttons let you save a pattern to the selected memory location, and load a stored pattern from memory. Control Voltage (CV) and notelength values are stored. Use the PATTERN NO. knob below to select the memory location to store the pattern to or read from. Eight different patterns can be stored.
- NOTELENGTH: Select the notelength for the current step. Choose between whole-, half-, quarter-, eighth-, sixteenth- and thirtysecondth notes.
THE MIDDLE/"DUAL" SECTION
- PATTERN NO./MAX STEPS: In SETUP mode, this knob lets you specify the memory location to store a pattern to, as explained above. In RUN mode, it sets the maximum number of steps the sequencer cycles through. It works in all DIRECTION modes.
- SETUP/RUN: This switch enables either the SETUP or RUN mode.
- DIRECTION: Switches step direction between FORWARD, REVERSE, PENDULUM and RANDOM.
THE RUN SECTION
- INT/EXT CLOCK: Switch between internal and external clock. The external clock signal is received through the EXT CLOCK IN jack input below.
- INT CLOCK SPEED: Adjusts the speed of the internal clock.
- START/STOP: Starts or stops the sequencer.
- EXT CLOCK IN: Jack input for external clock pulse.
- TRIG OUT and CV OUT: Jack outputs for trigger signal and Control Voltage.
- START/STOP TRIG IN: Jack input for external pulse to start or stop the sequencer.
