The Standuino fraAngelico Arduino Synthesizer

The Standuino fraAngelico is an 8-bit PWM digital synth, built on the Arduino platform.

It does not use any D/A convertor, but the sound is generated by \ one digital output pin using Pulse Width Modulation. Resolution of this technique to achieve different voltage levels is 8-bit, but in the true essence the output form the synth is just 1-bit because the output pin does jus 1 or 0 which makes distinctive digital character to its sound.

fraAngelico features:

  • size: 11 x 7 x 4 cm
  • MIDI input (MIDI Through by special cable)
  • 5 knobs
  • 3 switch menu buttons
  • 4 big performance buttons
  • 1 volume knob
  • grain synthesis
  • true digital LFO
  • envelope
  • 8 presets (4 user, 4 factory)
  • input voltage: 9V
  • Jack 3.5 output

The fraAngelico synth is available a kit for 50€, or assembled for 100€.

  1. [cheeky alert:] At first I thought it sounded like a really good quality shortwave radio– then I got a look at those sweet gold knobs!!

    [non-cheeky comment] Does make some kind of interesting noises for a noisy synth. I’d be curious how it responds to incoming MIDI notes– i.e., can you play melodies on it? For a moment there, I heard the sound like the synth line in “Nightlife Baby” by the cars. Could be a fun lil’ toy. Also if I was making a short retro sch-fi film, this might be a useful source for “malfunctioning ship” sounds.

    1. yep! on the lowest octave of a normal midi keyboard it “stores” the sounds you can achieve with the 4 standard buttons, but in the other octaves you can play melody lines! check out the demo with the korg nanokey on the website!

  2. INteresting concept the digital output. The synth can be used for some usefull noises and it’s worth the price

    There are more videos, this one with a midi keyboard. But I warn you, if you have a cat move him out of the room before play the video, I have scratch on my face.

  3. I just want to tell that Standuino offers no customer support at all. I bought the frauangelico, which is based on this synth. My unit was not functionning and they never replied my mails, although I was using an address that I know is valid (we talked about why my unit was shipped late). I would recommend to NOT buy from them because if you have a problem with your gear they will simply go mute. I was just stolen 100€ by these dishonest folks.

  4. well sorry that happened to you but I bought a kit fraangelico has standuino and I got it quickly (about 8 days) for delivery from Czech Republic to France, and I assembled without problems, and it always still works without any problems and I love it, I will never sell it because his sound is unique and has very particular grain, he is EXCELLENT for the melodies too !!! pure crazy synth !!!
