Behold! The first commercially available eurorack module from all round experimental fun-time positive excitement guy Sam Battle AKA LOOK MUM NO COMPUTER! Overveiw Octave Switch ad ds 0-4 volts—or 5 octaves—to the 1v/oct signal. Fine Tune has a one octave range. Tunershowsthenearestnoteand LEDs indicate wether it’s flat (left), sharp (right) or bang on (middle). Pulse Width can be adjusted from 0-50%. 1v/octinput. Additional Frequency CV input and attenuator. Pulse Width Modulation CV input and attenuator. Frequency Sync input. Works best with simple waveforms. Frequency Modulation CV input. Simultaneous Pulse, Ramp and Triangle outputs. Note that the outputs are unipolar audio signals with levels that vary from +4v to +8V. Calibration Trimmers. See next column. Your VCO comes pre-calibrated, but differences in power supplies might mean you can get improved accuracy with further adjustments to the trimmers. You may at least want to adjust the CNTR trimmer if C isn't right in the center of the Tune knob range. REF: Reference voltage at the 4V test point on the back. You should not need to adjust this. If you do, try to get it as close to 4V as possible without going over. CNTR: Center frequency. The VCO is set to produce C1 at the lowest octave setting on the octave switch and tune knob set around noon. You can adjust the center frequency without affecting overall tracking. TRK: Tracking. Use this to adjust the space between notes in relation to the 1v/oct input voltage and octave switch. This may be useful if your sequencer’s or keyboard’s tracking isn’t perfect. HF: High frequency tracking. This is unlikely to need adjustment, but is there to fiddle with if you feel tracking at high frequencies could be improved.
