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 3

I am continuing my experiments with different ways of visualising a step sequencer and this comes from from a suggestion by Twitter user @AxWax - using a NeoPixel ring. https://youtu.be/u4WNbgCWvds 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 … Continue reading Arduino MIDI Rotary Encoder Step Sequencer – Part 3 →

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 MIDI Rotary Encoder Controller

I've finally gotten around to having a play with rotary encoders.  It has been on my "to do" list for a while, so I thought I'd start with a rotary encoder version of my Arduino MIDI Button Controller which can select a voice and send the corresponding Program Change message out over MIDI. https://youtu.be/uxT_RQs1MXM Warning! I strongly … Continue reading Arduino MIDI Rotary Encoder Controller →

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 →

Lo-Fi Orchestra – Fanfare for the Common Man

Here is another piece for my Arduino tones- Aaron Copland's Fanfare for the Common Man.  This is scored for four horns, three trumpets, three trombones, tuba, timpani, bass drum and tam-tam. The Arduino tones provide the brass.  The VS1053 provides the timpani and bass drum, but the tam-tam was a bit problematic.  Eventually I decided … Continue reading Lo-Fi Orchestra – Fanfare for the Common Man →

Lo-Fi Orchestra – Janacek Sinfonietta

I've been thinking about other things I could play on my Arduino tones and they seem particularly suited to fanfares, so here is the opening movement of Janacek's Sinfonietta. For details of the projects used in this performance: Arduino Tone One Year On! Arduino MIDI VS1003 or VS1053 Synth https://youtu.be/BroTjZgu1Bs All music rights and copyright … Continue reading Lo-Fi Orchestra – Janacek Sinfonietta →
