I’ve made a little stop in zynthian software development and have finished a little project that has been over my desktop from a few months ago. Here is the result:
The firmware allows to control upto 24 MIDI-CC parameters arranged in 3 layers: red, green, blue. You can change the layer by clicking the top-left encoder.
Excelent stuff! I really love it …
Please, tell me, what do you think is the better way of implementing this “preset switch functionality” for Zynthian. For instance … what MIDI messages are you using in your pedal switch?
while I was still puzzling to get my basic ZBox up and running, I was trying to think about extensions like adding a number of poteniometers to the system - and now your controller developments catapults me into a completely new universe with the ability to make online and offline (not on stage) parameter input a real snap. your new Controller box opens the doors for a heap of exciting new parameter controls…
When you find the time, PLEASE
Tell me if you are going to offer this also as kit ?
… if yes - I’d already now want to order one;
… if no - please indicate where to find parts and building instructions
(I am having some problems to find a quote to thhe rgb led ring you have used.
In addition:
… would it be possible to use a teensy (3.2 or 3.5) instead of the ATmega ??
I would like to write a “tutorial” for the MIDI-USB controller, but it’s still a prototype and i want to improve some things before. When it’s ready and i’d wrote the guide, perhaps i could offer kits, but it’s not sure.
Anyway, it’s a really simple device … but a mess to wire!!!
Regarding your questions, yes, it could be done with a teensy. No problem with it. The code should compile with very little changes …
Hi again!
thanks for your answer - i’ll just wait for your tutorial to come about.
Maybe your prototype could be one prime example for shifting RPi GPIO to some external device / protocol which is currently discussed triggered by “good ole” C0d3man - anyway that ideahas some tough corners to get around…
Just reading your comment about the wiring, also found in a few other comments, I can say that I did not find it very difficult at all after I had puzzled out some part orientations, pin numbers ec which I did not find in the tutorial or in the wiki. I have then tried to upload / enter my so very clever comments (mainly pictures/drawings), but I have not figured out how to do that.
OMG, so many things to learn beforeI can become an efficient community member …
Maybe I need a kick to my butt from you directing me how to do that ;-))))) ?
I’ve used the Nord Modular G2 a fair bit and it uses encoders and leds in a very similar fashion to this, with an x-y array of switches to select many, many parameters of it’s virtual synth’s.
It’s easy to get a little bit lost in the heat of the moment, and the LCD displays on the Nord help a lot.
Would you plan on putting any sort of display on the MIDI-UB controller to aid in such a situation or would this be handled by the zynthian display?
Also, the wiring is more or less the same mess, jajaja! I really like the idea of having the assigned parameter name on each rotary, so i will try to build a prototype as soon as i have some spare time … … perhaps never!!
Been thinking…
24 knobs, sure that"s better than nothing…
But zynaddsubetc needs more…
But sure, as long as we can decide which parameters are concerned, it’s a geat add on…
But could we convert your module into a 24 analog input controller ?? 8 of them would even be enough… That would allow the use of external pedal, ribbon, joystick, breath controller, even an old ARP 16 note sequencer, or an envelope follower… Let’s dream : 24 envelope followers, to control 24 harmonics… A zyncoder…
Ooooops…
I realize how silly I am… These are encoders, you used, Not potentiometers… So of course, the conversion would not be possible… Sorry for disturbing…
Enjoy the day anyway…

Hi! I hope you’re well. I’ve been randomly researching small sized midi controllers online and I landed upon yours in an simple Google search via images. I must say that I’m impressed with what you’ve built and I also say I had no clue about Zynthian and what’s it’s about until I’ve stumbled upon your creation. I’m looking into creating something like this to control a sound module via Midi 5 pin. I’ve never ventured into programming, I’ve never ventured into the world of Pi etc. I’d like to create a similar unit but with linear faders and the ability to assign and NAME the faders. I won’t need the audio capability of the Zynthian. The unit will strictly be used to control the modules parameters via MIDI CC. Can I do away with the Soundcard? Any help? Thanks in advance.
Actually this project doesn’t work without a soundcard.
If you need a fader-to-midi module, there are better suited projects in the web.
I can’t name them except of MidiBox which might be a little to big/expensive for your purposes though.
or would we use different colours for different layers?
