Power Connection
The module comes with the required power cable for connecting to a standard Eurorack power supply system. Follow these steps to connect power to the module. It is easier to make these connections before the module has been mounted into a rack case.
- Turn the power supply or rack case power off and disconnect the power cable.
- Insert the 16-pin connector on the power cable into the socket on the power supply or rack case. The connector has a tab that will align with the gap in the socket, so it cannot be inserted incorrectly. If the power supply does not have a keyed socket, be sure to orient pin 1 (-12 V) with the red stripe on the cable.
- Insert the 10-pin connector into the socket on the back of the module. The connector has a tab that will align with the socket for correct orientation.
- After both ends of the power cable have been securely attached, you may mount the module in a case and turn on the power supply.
Connect end P1 to the module socket
Connect end P2 to the power supply
Installation
The necessary screws are included with the module for mounting in a Eurorack case. Connect the power cable before mounting.
Depending on the rack case, there may be a series of fixed holes spaced 2 HP apart along the length of the case, or a track that allows individual threaded plates to slide along the length of the case. The free-moving threaded plates allow precise positioning of the module, but each plate should be positioned in the approximate relation to the mounting holes in your module before attaching the screws.
Hold the module against the Eurorack rails so that each of the mounting holes are aligned with a threaded rail or threaded plate. Attach the screws part way to start, which will allow small adjustments to the positioning while you get them all aligned. After the final position has been established, tighten the screws down.
Controls
- FADER 1 – this fader has two functions: in free-running mode it sets the frequency for LFO 1; otherwise it acts as a master fader for the other three faders to reference.
- FADER 2 – in free-running mode this acts as frequency control for LFO 2; otherwise it acts as an offset against the master for LFO 2.
- FADER 3 – as fader 2 but for LFO 3.
- FADER 4 – as fader 2 but for LFO 4.
- FREE LED – when this LED is lit the FOUR LFO is in free-running mode.
- MODE – use this switch to select the action for sockets 16. In RESET mode a gate applied to the socket(s) will cause the waveform(s) of the LFO(s) to reset; in SYNC mode the LFO(s) will sync to a clock sent to the socket(s).
- TOGGLE – use this button to switch between:
- Free-running, where the four LFOs work independently.
- Quad, where LFOs 2 – 4 are slaved to LFO 1 but are 90°, 180°and 270° out of phase respectively. Faders 2-4 and sockets 10-12 control the amplitude of LFOs 2-4.
- Phase, where faders 2-4 set the phase of LFOs 2-4 against LFO 1. Sockets 10-12 allow further control of shift from external CVs.
- Divide, where faders 2-4 set divisions of LFO 1’s frequency for LFOs 2-4. Sockets 10-12 allow further CV control.
- ASSIGN – sets the waveform that will be output from sockets 18. Choose between sawtooth, ramp, triangle and trapezoid. This is a global setting which will affect all four LFOs.
- FREQ – use this socket to control the frequency of LFO 1 from an external CV source, in the range -5 V to +5 V.
-
-
- – FRQ/PH/DIV – use these sockets to allow external CV control of LFOs 2-4 according to whichever mode the FOUR LFO is in. range in all modes is -5 V to +5 V.
-
- QUAD LED – this LED is lit when the FOUR LFO is in Quad mode.
- PHASE LED – this LED is lit when the FOUR LFO is in Phase mode.
- DIVIDE LED – this LED is lit when the FOUR LFO is in Divide mode.
- RESET/SYNC 1 – a gate or clock applied to this socket causes different actions according to mode:
- In SYNC mode it will synchronize LFO 1 to the external clock.
- In RESET mode when the LFOs are free-running it will reset the waveform cycle of LFO 1.
- In RESET mode when the LFOs are in QUAD, PHASE or DIVIDE it will reset the waveform cycles of all four LFOs.
- RESET/SYNC 2 – a gate or clock applied to this socket causes different actions according to mode:
- In SYNC mode it will synchronize LFO 2 to the external clock.
- In RESET mode when the LFOs are free-running it will reset the waveform cycle of LFO 2.
- In RESET mode when the LFOs are in QUAD, PHASE or DIVIDE it will pause all four LFOs.
- RESET/SYNC 3 – a gate or clock applied to this socket causes different actions according to mode:
- In SYNC mode it will synchronize LFO 3 to the external clock.
- In RESET mode when the LFOs are free-running it will reset the waveform cycle of LFO 3.
- In RESET mode when the LFOs are in QUAD, PHASE or DIVIDE it will reverse all four LFOs.
- RESET/SYNC 4 – a gate or clock applied to this socket causes different actions according to mode:
- In SYNC mode it will synchronize LFO 4 to the external clock.
- In RESET mode when the LFOs are free-running it will reset the waveform cycle of LFO 4.
- In RESET mode when the LFOs are in QUAD, PHASE or DIVIDE it will shift the assignable waveform to the next option on all four LFOs, regardless of the setting of switch 8. The waveform selected by switch 8 will be selected again if the mode is changed.
- SINE – sine wave outputs for each LFO.
- ASSIGN – assignable waveform outputs for each LFO, according to where switch 8 is set.
- SQUARE – square wave outputs for each LFO.
PRECISION
Pressing and holding button 7 puts the FOUR LFO into precision mode to allow precise adjustment. The LED for the current mode will flash, and the faders will make fine adjustments around the centre point. When exiting precision mode the faders will not necessarily indicate the current setting, so the relevant LED will continue to flash to show this.
FIRMWARE UPDATE
On the edge of the circuit board next to the mode switch (6) there is a micro USB socket for updating the FOUR LED’s firmware, using the SynthTribe application.
HINTS AND TIPS
- Use the output of one LFO to modulate the selected parameter of another. Or cascade your modulation . . .
- In free-running mode use a square wave from one LFO to reset another.
