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 PWM Sound Output

Up to this point I've been using a range of audio output options, of varying fidelity, including outputting "PWM" using the Mozzi synthesis library, but I haven't actually experimented with PWM, or Pulse Width Modulation, itself directly so thought it was time I looked into it a bit more. In Part 2 there is an … Continue reading Arduino PWM Sound Output →

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 →

Arduino Mux Slider Phased Relays

I've mentioned before that I quite like some of Steve Reich's ideas for weird rhythms and percussion and I know thing he liked was rhythms going in and out of phase. So having just received a new bank of eight relays I thought it would be fun to combine it with my 8-pot slider board … Continue reading Arduino Mux Slider Phased Relays →

Arduino Multi-Slider MIDI Controller – Part 3

This is an expansion of the multiplexer version of my Arduino Multi-Slider MIDI Controller from Part 2 to add a further 8 potentiometers. In a future project, I build a "shield" to make linking to the pots easier. Warning! I strongly recommend using old or second hand equipment for your experiments. I am not responsible for … Continue reading Arduino Multi-Slider MIDI Controller – Part 3 →

Arduino Multi-Slider MIDI Controller – Part 2

This is the multiplexer version of my Arduino Multi-Slider MIDI Controller. In part 3, I extend it to 16 potentiometers. 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 tutorials for the main concepts used in this … Continue reading Arduino Multi-Slider MIDI Controller – Part 2 →

Arduino Multi-Slider MIDI Controller

A while back I bought some cheap slider potentiometers, so decided to get them out and give them a go. This first project is using eight with an Arduino Nano as a multi-slider MIDI controller, expanding on my Arduino Simple MIDI Controller. In part 2, I show a version that uses a multiplexer. In part 3, … Continue reading Arduino Multi-Slider MIDI Controller →
