SERGE MODULAR Installation Always turn the eurorack case off and unplug the power cord before plugging or unplugging any eurorack power cable . Do not touch any electrical terminals when attaching any eurorack power (bus board) cables . The Serge GTO is an electronic music module requiring 50mA of +12VDC and 50 mA of -12VDC regulated voltages and an appropriate power connector to operate .

SERGE MODULAR A PULSE wave (orange) into SMPL or RUN does not affect the Cycle . • Sample Mode: When the SMPL switch is up, the GTO moves (cycles) only for a very short period of time when a pulse wave triggers the SMPL input - irrespective of the pulse length: A PULSE wave (orange) into SMPL allows the GTO to run for a moment before being frozen again .
Page 6
SERGE MODULAR RUN Mode: If all of this is not flexible enough gor you, the RUN input comes into play . Here, the GTO • runs freely while the signal is high and is held when the signal is low, i .e . the duty cycle of the pulse signal determins the ratio of running to stopping .

SERGE MODULAR RUN Mode: Here again the signal is frozen as long as the RUN input is high - the GTO acts like the left • side (SMOOTH MODE with HOLD): GTO (yellow) acts as in SMOOTH mode, RUN (orange) acts like HOLD . Please note that RUN and SMPLE IN can be combined for even more complex waveforms and modulations: GTO output (yellow) as affected by RUN (green) and SMPL (orange) .

SERGE MODULAR between -12V and +12V . This is useful for generating complex control voltages and for patching a random voltage generator . In fact, the Random Voltage Generator module is a Smooth & Stepped Generator internally patched to function exclusively as such . Note that a Noise Source is needed for use of the GTO as a random voltage generator .
