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!

These are the key Arduino … Continue reading Arduino Phased Step Sequencer →

Arduino MPR121 MIDI Touch Piano

A comment on the Arduino MPR121 Touch Piano pointed out that I never went as far as building a 48-note MIDI touch piano. In principle all the bits are there between that post and the Arduino MIDI Touch Piano so this post brings the two together to do just that. https://youtu.be/fdxiHUlXFbY These are the key Arduino … Continue reading Arduino MPR121 MIDI Touch Piano →

Arduino Mozzi Sample Drum Sequencer

This project combines the Arduino Mozzi Sample Drum Machine with the code from the Arduino VS1003 Drum Machine and the buttons from the Analog Keypad Tone Controller. https://youtu.be/e_hVGe0Z_mE Warning!

Arduino Mozzi Sample Drum Machine

There is still a lot to explore with the Mozzi synthesis library, so today I wanted to look at the "sample" options - getting the library to play pre-recording samples of sounds. https://youtu.be/eB7vzF_4zxY Warning! I strongly recommend using old or second hand equipment for your experiments. I am not responsible for any damage to expensive … Continue reading Arduino Mozzi Sample Drum Machine →

Analog Keypad Tone Controller

I've picked up a couple of cheap 3x4 keypads so thought I'd look at its potential as a music controller. https://youtu.be/C1n5NBVvfLg Warning!
