Raspberry Pi v1 Model B Synth Board

If you've been following along, you'll know I've been playing around with an original Raspberry Pi v1 model B as the engine for some digital sound synthesis.  This is a slight project tangent to build an analog IO and MIDI add-on board.  Note that this does not conform to any standard for Raspberry Pi add-ons … Continue reading Raspberry Pi v1 Model B Synth Board →

Arduino MIDI LED Step Sequencer with MCP3008

Having now experimented with an SPI eight-way analog to digital converter in the shape of the MCP3008, I wanted to build a step sequencer where the type of analog input was configurable.  This project allows you to choose between the following options for controller the steps of the sequencer: The native analog inputs on the … Continue reading Arduino MIDI LED Step Sequencer with MCP3008 →

Arduino Mozzi FM Synthesis with MCP3008

I'm always on the look out for new ways of building control modules for my Arduino synthesizers, so when I discovered the MCP3008 SPI 8-channel analog to digital converter, I thought I'd give it a go with my Arduino Multi-pot Mozzi FM Synthesis. https://youtu.be/A5if3Y4u8aM Warning! I strongly recommend using old or second hand equipment for your … Continue reading Arduino Mozzi FM Synthesis with MCP3008 →

Auduino Slider Waveform Granular Synthesis

Now I have a version of the Auduino that will use a wavetable as the grain for the granular synthesis, I can start some alternative experiments, so first of all I thought I would try to use my slider potentiometers to build the wavetable. https://youtu.be/HABkDbIHvO8 Warning! I strongly recommend using old or second hand equipment … Continue reading Auduino Slider Waveform Granular Synthesis →

Arduino MIDI Slider OLED R2R Waveform Generator

This project moves on a step from my Arduino MIDI Slider R2R Waveform Generator and adds a small 0.96" OLED I2C display. https://youtu.be/MGwdu017e00 Warning! I strongly recommend using old or second hand equipment for your experiments.  I am not responsible for any damage to expensive instruments! These are the key projects for the main concepts used … Continue reading Arduino MIDI Slider OLED R2R Waveform Generator →

Arduino MIDI Slider R2R Waveform Generator

When I first started looking at using fader/slider potentiometers I always anticipated using it to generate waveforms for my Arduino MIDI R2R Digital Audio board.  But as that is currently part of the Lo-Fi Orchestra, I decided I'd build a new one, hence the diversion into using PWM first whilst I decided exactly what to do. … Continue reading Arduino MIDI Slider R2R Waveform Generator →

Arduino MIDI Slider PWM Waveform Generator

This is a short update, to demonstrate the MIDI version of my Arduino Slider PWM Waveform Generator. A future project shows a similar system using an R2R ladder. https://youtu.be/chMNcMcGbXY Warning! I strongly recommend using old or second hand equipment for your experiments.  I am not responsible for any damage to expensive instruments! These are the key … Continue reading Arduino MIDI Slider PWM Waveform Generator →

Arduino Slider PWM Waveform Generator

Having finally been through the details of PWM audio output, I can now link this up with my 16 slider potentiometers and start creating more complex waveforms by actually "drawing" out the wave with the pots. https://youtu.be/PbkMxU_cBL0 Warning! I strongly recommend using old or second hand equipment for your experiments.  I am not responsible for … Continue reading Arduino Slider PWM Waveform Generator →

Arduino Phased Step Sequencer

After using my slide potentiomers to control the timing and phase of rhythm, I wanted to turn my hand to pitch.  This is my first experiment. https://youtu.be/AWbLFKj6VMk Warning! I strongly recommend using old or second hand equipment for your experiments.  I am not responsible for any damage to expensive instruments! These are the key Arduino … Continue reading Arduino Phased Step Sequencer →
