Getting Started with the Fluxamasynth for Arduino

  • 5000

Sunday November 18th, 12PM to 3PM at AS220 Labs

In this 3 hour session you'll learn how to use the Modern Device Fluxamsynth, a platform for making electronic musical instruments that are generative or have alternate interfaces. The Fluxamasynth is an add-on for Arduino, where you write simple programs using the Modern Device Fluxamasynth library. In this workshop we will use a minimal set of inputs to get started (two buttons, a pot and an AMBI light sensor).

Here are a few suggestions an what you can use the Fluxamasynth for:

  • Make your own MIDI instrument with unconventional analog sensors
  • Create algorithmic compositions
  • Use it in a homebrew pinball machine to generate music and sound effects
  • Build an unusual percussion device
  • Augment an analog instrument with a Fluxamasynth-based hyperinstrument

In the gallery above is an image of a Fluxamasynth-powered instrument made by Ed Potokar of Potophonics. We won't be getting into physically constructing instruments in this workshop, just the basics of getting started and up and running with programming. There is no soldering involved in the class either (photo is of a Benjolin-making workshop).

Workshop participants will a sneak preview of the new Fluxamasynth 32 all-in-one ESP32-based board.

The Fluxamasynth is based around a chip from Dream Sound Synthesis that would typically drive the sound on a Karaoke machine or keyboard. It has a built-in wavetable with 128 general MIDI sounds and an additional set of 128 variations and dozens of percussion sounds. It can play music in 64-voice polyphony without effects or 38 voices with effects. Here are some additional features:

  •     14 bits of pitch bend range
  •     Access to fine and coarse tuning in cents
  •     Access to low level wavetable parameters
  •     Stereo line level output
  •     Master volume and per-channel volume control
  •     4-band Equalizer
  •     Chorus, flange, delay effects
  •     8 Reverb effects
  •     Spatial effects

This workshop is free to attend, but has a $40 materials fee. You'll go home with a Fluxamasynth Shield and a custom board that has a minimal set of inputs and sensors that we'll be working with. If you already have a Fluxamasynth board or want to try before you by, drop me an email at and I'll put you on the list.

Location and Parking.   The AS220 Labs is located at the Mercantile at 131 Washington Street Providence, Rhode Island on the 1st floor. The shop's entrance is located at the back of the building on Lucie Way; the shop's double doors are at the Northwest corner of the building. There is 2 hour metered on street parking available, and parking is free on Sundays. We are also located near a parking garage with entry on Washington Street, look for the big blue parking sign.

Important Class Policies.   Please be as respectful of the short time you and the other participants have to learn and be as on time as possible. If you arrive more than a half an hour late we will not be able to teach you. Please plan ahead, it always takes time to find on street parking. To cancel your reservation must email at least two weeks in advance, or risk losing your payment.

Cancellation of Classes.  If minimum number is not met in class enrollment, the teacher may opt to cancel class. If this is the case, we will give a full refund of class payment and first choice to enroll in future classes. We will attempt to give as much notice as possible, thank you for your understanding.
