Hi my name is Matt, and I am building a modular synthesizer, It's going to be awesome.
My first priority is to build myself a bank of filters I can use to process other instruments. Along with a few other bits such as an ADSR, LFO and MIDI to CV converter.
Because of space considerations in my flat I have decided to use the Frac Rack format as eventually it'll fit into a pre-existing 19" racks, though at this stage I may very well decide to build custom cases out of wood and tolex.
Modules in progress
- Polivoks Filter Clone
- Based on schematic from here
- using individual op-amp ICs and built on pad-per-hole
- 556 based dual ADSR
- MIDI-CV converter
- based around arduino uCto allow for user based development
- support for different tuning systems
- future expansions will support programmable CV quantisation and arpeggiation
- +-15v PSU
Modules in the planning stages
- Ian Fritz Chaos Modules
- George Hearn VCO
- Sample and Hold
- Noise Generator
- Wavetable Oscillator
- A 556 based chime module
- 4 Voltage Controlled FM oscilators
- 2 Simple AR generators
- pitch inputs
Things I have learned
As I am new to most of this stuff I am leaning things as I go on, some obvious, some not so obvious.
- ALWAYS use an RCD when building your own PSU
- This one is a bit of a no brainer really
- Plan your pad-per-hole layouts before you put soldering iron to board, this will save you time, brain-ache, money and components
