Arduino Twitter Follower R2R Tones

One thing I wanted to do as a follow-up to my Pico MIDI (H)Arp was to use some data from the Internet as the source for some generative music. This post is my first try at taking my Twitter follower data and turning it into sound. A follow-up project uses a Raspberry Pi Pico to turn … Continue reading Arduino Twitter Follower R2R Tones →

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 →
