This module was designed in order to create complex and intricated sequences out of three basic sequences provided by one or more external sequencers.
As a matter of fact, it is a kind of sequential (maximum six steps) multiplexer that makes it possible to route three analogue inputs to two different outputs.
For each step, a rotary switch offers nine possible routes (number sare for inputs and letters for outputs, A2-B1 reads output A receives input 2 and output B recives input 1) : A1-B1, A1-B2, A1-B3, A2-B1, A2-B2, A2-B3, A3-B1, A3-B2 and A3-B3. For the STEPs #2 to #6 the first position of the rotaries is the sequence RESET function.
Strictly speaking this offers more than 531.441 possible combinations !
The steps are shifted either using a push button or by an external GATE signal. The routing sequence is reset to start position using a RESET push button or by an external signal. Yellow LEDs indicate which STEP is active.
Note that it can be used also for sequencing-multiplexing three audio sources to two audio channels !
NOTE : Yves at YuSynth limited the circuit to 6 steps because of a 2U panel was too small for 8 rotary switches and jacks. However, the same PCB and components can be used to extend it to 8 steps. Read the notes on the schematics and see the different component layout versions. The Soundtronics components kit includes parts for the 8 step version to match our own front panel.
We all have our preferences when it comes to building our modular synth so we offer a range of products for the build:
- PCB, size 75 x 100mm
- 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
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.
