YuSynth Noise + S&H Module

This single modules integrates two sub-modules : a noise voltage generator and a sample and hold (S&H) processor.

The noise generator generates three different signals : white noise (evenly distributed frequency spectrum), pink noise (1/f frequency spectrum, that is with a 3dB/octave slope), and a slow varying random voltage (frequency smaller than 6Hz).

The Sample and Hold processor has an internal clock but can be driven from an external clock. The clock rate ranges from 0.1Hz to 100Hz. The clock I/O acts either as an clock input or as a clock output depending on the position of the EXT/INT switch. A yellow LED shows the clock rate. A slew rate is also provided (its behaviour either linear or exponential can be selected with a jumper on the PCB).

As a default, the input of the S&H processor is connected to the white noise source.

Yves designed three different PCBs : a PCB that integrates both the noise generator and the S&H processor (this board 7220-046), a PCB for the noise generator on its own (7220-045) and a PCB for the S&H processor on its own (7220-030). Thus one can build the module of one's choice, either combined or separate.

We all have our preferences when it comes to building our modular synth so we offer a range of products* for the build:

  • PCB
  • Individual components
  • Kit of parts (excluding PCB, knobs and connectors)
  • Knobs (Cliff KM20B)
  • Jack sockets
  • Power connectors
  • Front Panel
  • Back Panel
  • PCB Holder
  • PCB Holder Brackets
  • Panel PCBs
  • Wiring Leads

*Not all products are available at the time of writing but are in development

For the latest build information, we recommend visiting the YuSynth website at http://www.yusynth.net/Modular/index_en.html

However, we also include this build information in our product pages plus additional details relating to the complete module assembly using our front panel solution as they are developed.
