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 →

JC Pro Macro (V2) MIDI Controller – Part 2

Following on from the JC Pro Macro (V2) MIDI Controller as a step sequencer, this project shows how it can be used as a generic MIDI controller. https://youtu.be/LjU9QdAnlJg 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 previous projects … Continue reading JC Pro Macro (V2) MIDI Controller – Part 2 →

JC Pro Macro (V2) MIDI Controller

I was exchanging some messages with Jeremy Cook on Twitter about Arduino tones on Leonardo compatible boards (i.e. those driven by the ATmega32U4) and that lead to a conversation about his latest crowd-funding effort for a Pro Micro-based "Macro" keypad and rotary encoder.  One thing led to another and he very kindly sent me one … Continue reading JC Pro Macro (V2) MIDI Controller →

Arduino MIDI Rotary Encoder Multi-Track Step Sequencer

Now I have the option for multiple colours for my step sequencer displays, I thought it might be interesting to start experimenting with a "multi-track" step sequencer. https://youtu.be/oQc1IVoJLeQ 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 Rotary Encoder Multi-Track Step Sequencer →

Arduino MIDI Rotary Encoder Step Sequencer – Part 2

In my last post, I mentioned other display options for my rotary encoder step sequencer.  To be honest, I wanted an excuse to use some "LED bars" with a rotary encoder, so this post is more by way of an excuse to play rather than a serious option, but in reality it actually works quite … Continue reading Arduino MIDI Rotary Encoder Step Sequencer – Part 2 →

Arduino MIDI Rotary Encoder Step Sequencer

I'm thinking about other applications for a rotary encoder and one thought was to support a multi-step, step sequencer with just a single knob, so this takes the Arduino MIDI Step Sequencer and recodes it to use the rotary encoder and 7 segment display described in Arduino MIDI Rotary Encoder Controller. Here are some links to … Continue reading Arduino MIDI Rotary Encoder Step Sequencer →

Arduino Four-tone Multi-tones

I had reason recently to take a look at the ATmega32U4 microcontroller again.  This is used on the Arduino Leonardo and the Sparkfun Pro Micro and includes built-in USB functionality.  But it also has four hardware timers, so I thought I'd try to get them working with the three-timer Tone library. https://youtu.be/N0GdLr4a9hM Warning! I strongly … Continue reading Arduino Four-tone Multi-tones →

Arduino PWM Output Filter Circuit – Part 2

I've been using my solderless breadboard version of my Arduino PWM Output Filter Circuit quite a lot so thought it might be useful to commit it to protoboard and build it onto a simple shield. Warning! I strongly recommend using old or second hand equipment for your experiments.  I am not responsible for any damage to … Continue reading Arduino PWM Output Filter Circuit – Part 2 →
