Mini-Modular Noise Synth
The mini modular synth is a series of 4 circuit boards that offer a range of signal generators and processors.
The boards are designed to allow arduino style control “shields” to be connected via a row of input and output headers on either side. These control boards will hold miniature potentiometers and a bread board style patch bay. The emphasis of this design is on compact scale, sound experimentation and circuit development. It is not a traditionally “musical” synthesizer and is much better suited for making abstract sound patterns than it is funky bass lines (although it can do funky if you get creative). I am able to make the circuits small and cheap by opting out of including features like 1 volt/oct tracking and exponential signal conversions. Those features are replaced with tons of voltage control and lots of ins and outs for cross modulating craziness.
tested the VCF,VCA,VCO board and the S&H, RING MOD, RUNGLE board. It all works!
Now to test the touch controller. fingers crossed
I have assembled and tested the QUAD VCO. So far so good!
The boards are in and building has begun.
1. QUAD VCO (wide range VCOs from LFO to audio)
2. VCO/VCA/VCF (single voice module)
3. S&H/RING/RUNGLE(modulation and complex sequencer)
4. TOUCH CONTROL,PROGRAMMER (touch controlled voltage and preset bank)
stacking control boards
Layout is standardized to allow easy connection with stacking interface and control boards, or jumpers can be run to panel mounted hardware on a custom interface.
The stacking control board will enable the builder to connect all external hardware simply by plugging the control board on top of the module.
I will design these once the PCBs have been tested. All pots and switches will be mounted on the board and I intend to use Arduino style headers and bread board jumpers for all modular signal patching which will make this a powerful and very compact system.
*For all intents and purposes these designs can be considered UNTESTED and will most likely be modified. I will remove this note once they are tested and confirmed fully working.*
