So looking at that manual, you will need a midi 5pin DIN output for the messages. You can configure the microcontroller to send sysex messages that take in the value of a POT and send that value across using the format described in the manual. Page 67-78 details the sysex format you will need to use. This looks like a challenge! ---

Thanks for the info both of you. It is the 81z . I’m trying to work out what controls I want/need on a panel and what knobs and encoders etc would suit. Ideally I’d like to avoid a screen in favour masses of controls to play with. ![220px-Museum_of_Science,_Boston,MA-_IMG_3163](https://global.discourse-cdn.com/free1/uploads/lookmumnocomputer/original/2X/2/28a430b585763f2c248fca4c04c8e53f35dced71.jpeg) ---

So your basic polling loop would be looking at each knob or button or switch in turn, debouncing the buttons if necessary, then sending the relevant sysex message out if there has been a change. This is the pseudocode: ``` Initialise all parameters to default/initial values. Until hell freezes over do For each control do Read and possibly filter new value. If new value of control is different from the previous value then Store new value of control as current value Send appropriate sysex message over MIDI to update the parameter corresponding to the control Endif Done Done ``` ---

Cheers @Bitnik. Now all I need is a smart case tool to parse your pseudocode into something that will sit on an arduino Mega… oh, that’d be me. If anyone has any smart layout ideas for "performing " with FM do shout out. I just found a huge bag of linear 10k faders. Time to doodle. BTW many old organs used pots like flip switches with three or 4 set 'positions ’ that lock off. Can anyone remember what the toothed gate thing was called you could add to a pot to do this? Very sore and medded so if i dreamt these then welcome to my kickstarter 😃 Thanks again ---

I recommend the “Control Surface” Library. It just makes everything much easier. It handles the de-bouncing and analog filtering and a bunch of other boring things, and just gives you an easy to work with interface into midi with best practices built in. Also supports things like banks and multiplexers super easy out of the box. > **[Control Surface: Main Page](https://tttapa.github.io/Control-Surface-doc/Doxygen/index.html)** ---

That sounds like an amazing library! I love the advertised scalability from Uno/Nano right up to ESP32. I hope it works! ---

I have used it for 3 different controllers so far and can attest to the reliability and ease of use. Ive done it “the other way” and its just night and day. I have used a teensy 3.2 and arduino nano. If anyone has questions about how to use that library, we can make a thread and cover some basics and show code so its even easier for folks. If enough interest is here ill go ahead. Might do it anyways, but i just wanted to test the waters a bit, and its just an excuse to make a poll. _Poll ([view on site](https://lookmumnocomputer.discourse.group/t/my-build-progress/345/1779))_ ---

Perhaps a practical project like a MIDI box to plug into the midimuso like a drum pad or test gates and triggers? I have several arduino and teensy 3.2 I stumbled through with the MIDI library and teensy (pure data code writer thing - sorry) . Something we can do together might even help Sam? ---

don’t know shit about coding / programing , but it seems like something that would be useful to know at least the basics , make it easier to load others stuff into the arduino based projects . ---

I’m down to lurk and learn. I’ve go a Teensy4 thats being under used (Currently just a 4pad MIDI Trigger) and a couple nanos to tinker with. it’ll probably inspire me to finish the Big Button too @Farabide do you mean the notes’n’volts guy? I enjoyed his series about that. He said he is doing a Teensy4 project too. =) ---

Actually Dave’s channel is by far one of the best intros and projects like the granular and teensy are worth doing. This control surface looks… smarter to me and for what I want to do (make stuff do stuff) it’s less clunky. Dave’s code is excellent though "all hail your old pal Dave " ---

Also went to my local aluminium place and bought half a sheet (1.2m x 1.2m) of 2mm aluminium (it was 60aud). They were kind enough to cut it into 20cm strips, I’ve cut it down into 5, 10 and 20cm panels (with plenty of left over to do some longer 50 or 60cm panels if need be). Anyways more than I’ll probably need… For now… Also bought some black spray paint and silver paint pens in varying width tips (.7mm, 1.3mm and 3.5mm) ![IMG_20201102_170416](https://global.discourse-cdn.com/free1/uploads/lookmumnocomputer/original/2X/d/d24da4f7323ae6bc7171141d18cde7a8fc6f0f85.jpeg) ---

This circuit is very small, initialy it’s a schem for a pedal guitar signal i think, you didn’t add a circuit for adapted it to the synth level signal ? or maybe you use it with a Stomp box adaptater module ? ---

No I did not. Just 9v. Lucky there’s space on the board _scurries off to do research_ Totally open to any suggestions as to how so the in and out. ---

the synth have a big signal in contrary of a guitar, i’m not a specialist but it’s not good for the pedal guitar. to use guitar pedal with my modular i use A Stomp Box Adapter module, this one > [@AI006 Stomp Adapter Schematic Help](https://lookmumnocomputer.discourse.group/t/ai006-stomp-adapter-schematic-help/96): > > So I got the idea to build a Stomp Adapter from [AI Synthesis](https://aisynthesis.com/product-category/eurorack/)’ - [Schematic](https://aisynthesis.com/wp-content/uploads/2018/12/stomp-adapter.pdf) that is available for the [AI006](https://aisynthesis.com/product/ai006-eurorack-stomp-box-adapter/) from another member here in the Forum. I am curious if anyone is willing to take a look at my Strip Board Layout to see if it matches correctly with the Schematic! I am having a bit of confusion with the To Synth portion of the schematic… I know… ridiculous… it looks like the easiest bit… but simple things always become beyond over complicated in my head… lol. So I want to make sure that… it lowers the synth level to an instrument level to enter in the pedal, then increases it to obtain a synth signal again.
