Hex 1.0


HEX 1.0 is a digital polyphonic synthesizer with a capacitive keyboard, potentiometers for signal modulation and an adaptable looper that through its unusual shape explores new ways of.”Sed ut perspiciatis unde omnis iste natus error sit voluptatem accusantium doloremque laudantium, totam rem aperiam, ea




Lag is a real-time sound processing device. The signal sent through the left jack input (8), goes through the GAIN (2) stage and is fed into the circular buffer delay line. 


There are four potentiometers dedicated to sound manipulation. GAIN (2), RATE (3), SPREAD (4) and FEED (5) settings can be adjusted to turn your sounds into thick drones, bit crushed chaos, pitch shifted copies, junglist stutter, etc. RATE controls the sampling speed and overall delay time, while SPREAD is used to adjust the separation between the read & write “tape heads” within the circular buffer. The FEED potentiometer can also push the device to self-oscillation mode, enabling standalone usage.


Touch the golden touch pads (1) to additionally manipulate the DELAY and SPREAD parameters for manual vibrato-like effects and expressive sound design.


Push button (6) can be used to achieve the freeze/stutter effect. The stereo output jack (9) outputs two versions of the signal – 50% and 100% wet.



Lag also has a pitch-shifter mode which can be accessed by turning the SPREAD potentiometer fully clockwise and pressing the push button. In this setting, RATE controls the sampling speed and SPREAD adjusts the pitch-shifting frequency. FEED still controls the feedback, producing granular-like pitch shifted swells.


I /O

There is a triple header row next to the input jack for interfacing with external control voltages. The top pin is connected to GND, the middle to SPREAD and the bottom to RATE potentiometer. Both SPREAD and RATE expect a unipolar signal 0-5V.



COMPONENTS (tole je lahko v vrsti sosledno, če bo preveč teksta oz. lahko kar ven vržemo)

  1. 47uF capacitor / 1x 
  2. 10uF capacitor / 2x 
  3. 1uF capacitor / 2x 
  4. NE5532 chip / 1x 
  5. ATTINY85 chip / 1x 
  6. Push button / 1x

You will need a soldering iron, solder, pliers, tweezers and some patience. Before you begin the process, make sure you are working on a clean, well-lit surface. Be careful with the components, some of them are very small: take them out of the packaging one at a time, when needed. Most of the tiny SMD components are marked with numbers that match the numbers printed on the PCB. If you are new to soldering SMD components, we recommend watching some tutorials on YouTube beforehand. For the assembly video, visit our website. In any case, take it slow, go step by step and enjoy the process of building your own HEX. It’s like a puzzle that you can still use and play with afterwards. Oh, and if you have any questions, do not hesitate to write us. Have fun!


  1. Solder the 47uF capacitor / 1x * 
  2. Solder the 10uF capacitor / 2x * 
  3. Solder the 1uF capacitor / 2x * 
  4. Solder the NE5532 chip / 1x * 
  5. Solder the ATTINY85 chip / 1x * 6. Solder the push button / 1x
  6. Solder potentiometers / 4x – (do not put the knobs on before you are finished with the whole process) 
  7. Header pin / 1 x 3 pins (place the boxy part on the bottom of the PCB and allign with the base) solder 
  8. Solder 3.5mm jack / 2x
  9. When finished soldering, check if all of the solders are well connected to the components.
  10. Clip all of the excess steel leads on the bottom side and see if it fits the wooden base. 
  11. Drive in the nuts and tighten the bolts.
  12. Align potentiometers to central position and attach the knobs.

* The marked components are polarized. For the correct allignment observe printed graphics on the PCB.
