- Page 3 Description Logic gates were originally used for the implementation of Boolean functions in computation and in electronic devices. These functions were performed on one or more binary inputs to create a single binary output. In music synthesis, this concept can be appropriated for many things including the creation of interesting rhythmic patterns as well as patch- based problem solving.

Page 4: Installation
Installation 1. Confirm that the Eurorack synthesizer system is powered off. 2. Locate 4 HP of space in your Eurorack synthesizer case. 3. Connect the 10 pin side of the IDC power cable to the 2x5 pin header on the back of the module, confirming that the red stripe on the power cable is connected to -12V. - Page 5 eãs | /es/ | noun (nature) a cascade of water falling from a height, formed when a river or stream flows over a precipice or steep incline.

- Page 6 Gate Logic AND & NAND Gate Logic: In AND gate logic, voltage is held HIGH at the output if all the inputs to the AND gate are held HIGH. If none or not all inputs to the AND gate are HIGH, the output will be held LOW. NAND gate logic is the inverse of AND gate logic.

Page 11: Patch Examples
Patch Examples Pulse Syncing: Summary: A primary use case for AND logic is to synchronize two pulse signals. By connecting a steady clock signal to AND Input 1 connecting a faster random pulse signal to AND Input 2, the Output will generate random pulses only when the steady clock signal is held HIGH. - Page 12 Pulse Mixing: Summary: A primary use case for OR logic is to mix two pulse signals. OR Input 1 By connecting a pulse signal to and a different pulse signal OR Input 2, the OR Output will generate a sum of the two pulse signals, creating a more intricate pulse pattern.
- Page 13 Rhythmic Variations: Summary: Any two different clock signals or gate/trigger patterns can be connected to one of the logic gates for interesting rhythmic outputs. Experiment with different clock rates and logic gates. Take advantage of the internal normalling and use three clock signals or gate/trigger patterns instead of two.
- Page 14 CMOS-Style Ring Modulation: Summary: Connect two different audio signals to both XOR Inputs for CMOS-style ring modulation effects. This style of ring modulation is often used for synthesizing cymbal sounds. It’s also found on many classic synthesizers as a way to add overtones to the primary oscillator waveforms.
