Introduce yourself!


I am Walt, a hobby musician and professional electronics engineer living in the English seaside town of Clacton-on-Sea. I have very little formal music training but dabble in whatever I can, mostly guitar. I have a selection of instruments including MIDI keyboards, wind, guitar and drum controllers which I intend to dust off and drive my new Zynth. I have been designing and building a synth for the past few years (actually, probably decades!!!) but the latest iteration was so similar to Zynthian that when I read your blurb I decided to abandon (or mothball) my efforts and try this - so far, none too shabby. I want a device that I can program and control with lots of knobs (like we did in the 1970s) but can also be used as a simple and small live tool with recall of all those lovely soundscapes so plan to have a hardware controller for sound design and a box (or two) that lives in my gig bag.

I have been using gnu/linux since the turn of the century and am an advocate for free and open source adoption. I participate in several open projects (and host a few) and have much experience with project management, issue management, version management, release management and test management. (That is a lot of management - like a Hale and Pace sketch (for our UK viewers) :slight_smile: ).

I hope this project turns out to be the panacea I have been looking for and allows me to make music rather than just design the tools to do so. I have read a lot of the discourse and you look like a fairly friendly bunch. I may stick around…


Welcome aboard! Please accept a complimentary glass of champagne . . .

My Parents live in Harwich . . . Did you visit Maplin in Southend…? :smiley:

It all sounds similar to my own journey. . . .Trying to build something around a hifiberry amp and wondering how to get latency down…

It’s like the 70’s build but now you get a community . . .

…Even if it’s only this one … :smiley:

Yes, I remember Maplin when it was just that little shop on the A13. Later I used to connect to their dial-up ordering service via an acoustic coupled modem and be excited at being presented with a text based menu that I could traverse, slowly… Maplin had a chequered history and rather lost its way. I long since stopped relying upon it for my supply of electronic components. Farewell old friend :cry:


You have stepped-in with really good energy, Walt! Welcome on board!
We have a lot of funny work to do by here … I hope you enjoy a lot in our little Zynthianverse :grinning:

Hello fellow zynthonians !

My name is Steven, I’m 41 and from Belgium.

I’m a unix system administrator with a passion for (micro)electronics and building things.
No music skills whatsoever, but messing with electronics and listening to randomly generated sounds keeps me sane :stuck_out_tongue:

Since my attention span is fairly short ooh look a butterfly there is always some half finished projects on my desk.

My favorite toys: hackrf, plutosdr, prusa i3, a vast selection of microcontrollers and SOC’s

Currently working on:

  • zynthian box (7" touchscreen, pi 3B, clone hifiberry dac+, mcp23017 with assorted encoders & launchkey mini)
  • Teensy midi sequencer (teensy 3.2 with potentiometers, buttons and oled - loosely based on teensy examples and adafruit Fifteenstep)
  • another teensy controlling an OPL2 sound board; still looking for a nice way to integrate another soundboard into my zynthian setup - I have no HW mixer)
  • RC remote control (STM32 with oled and NRF24’s to control a 3D printed spider)
  • some assorted trinkets for integration with esphome and

Hope you are having a great day and see you around the forum!

I am Vincent, I went to this forum to speak about midified Open Theremin and Zynthian one or two years ago.

At this time I didn’t have my Zynthian but had an oportunity to discover how this project was interesting.
I had a SM Pro Audio V-Machine to cover my need for software synth on stage but I kept the Zynthian in my list of future project…

Recently, I advertised to a friend of mine the Zynthian, telling him that he would take no risk and that I would buy him his device if he was not totally satisfied.
Unfortunally he left his band and get too much buzy for zynthian project. Then he took advantage of my proposal and sold me his Zynthian.

Here I am, I have my Zynthian ! I am having a lot of fun and I am ready to share tips, help to fix problem and, most important, make some music…


Welcome aboard . . .

So easily they fall into the trap!!! . . . :face_with_monocle:


Did I fall into some linguistic trap ? “Play some music” maybe… I spent one hour or so on Wordreference to see if I made any English speaking error ! :thinking: and didn’t find any answer…

Wyleu 's"ceterum censeo" is to ask for an audio footage.


OK ! I got it…

Some theremin voices trying to be celestial (some LV2 step sequencer on Zynthian + midi theremin on my V-Machine):


A lovely closing shot of many a film!! :smiley:

Have you built a kit or do you have desktop constructions we are desperate to see . . . . .:smiley:

… and hear :face_with_monocle:

I really don’t want you to get blind :wink: But I promise that I will post a picture once it won’t be such a mess anymore !
