This entire series has been very helpful and entertaining to watch. One bit of advice for anyone, regarding the step drill - the expensive bits are very useful and worth their price. The cheap ones are a complete waste of time and cash. Heads-up
Hey man, you really, really need a video that is just demonstrating the sound of this synth. I don't even really know what it is capable of. What little I have heard sounds good, but before I go and build it, I'd like to hear, y'know? Really cool work, thanks for the very thorough instructions!

I believe you could parallel the MIDI in to another MIDI jack to make a MIDI Through port
Hey, I just built the synth with your line level mod and I'm looking at the MIDI upgrade now. I was wondering if there is an easy way to swap it back to a drone synth (by switching a digital pin high/low maybe) when there is no MIDI signal coming in. Thanks for your videos, notes and work mate, really great stuff. Super fun instrument!
I was really hoping you would touch more on the code side of things.... also ive been watching most of your videos expecting to find one of them talking about the midi library and all the different functions. but i can't seem to find any. is there one that i have missed? if so could you please link me to it? if not then i wholeheartedly recommend you make a video about coding the arduino to send and recieve midi (i know a very basic one was made but im talking more elaborate, like different CCs and and what not.) Just a simple video about the different functions and how to go about building a basic midi script... in terms of how to organize the code and how the code progresses and loops. Thank you for all the work and effort you put into these videos, i definitely learned A LOT and am very tempted to build this auduino after watching your videos. and i also learned a lot about project box construction as this was a huge weakspot for me.

+fayekhelmi Hi Fayekhelmi. In this series I have covered Building a MIDI circuit, Send MIDI note Data, Receiving MIDI Notes data, and receiving MIDI CC messages. The examples are simple but show fully functional programs that you can modify for your requirements. You can find them in a playlist on my channel.
Hey, I believe you can add CV to this as well. You can use photosensitive sensors soldered to the positive and negative of the pitch potentiometer's and taped facing the sensor put a led. The led can be soldered to and audio jack and there you go CV! I haven't tested this but I'm pretty sure it would work.
The intro is quite The trip :)

Hi, Great project. Is this midi synthesizer polyphonic?
@NotesAndVolts

Hi Sourav. It's a mono synth.
awesome!!!!!
0/ using hand drill 1/ the box is secured for drilling using a very weird way, it can slip off while drilling 2/ the first drill bit is too large for first hole, i would use 1.5 or 2 mm instead 3/ the step drill bit should have less rpm on larger diameters 4/ the rivets are too long and maybe should have used closed ones into device for better look 5/ tin the wires before soldering them anywhere 6/ the midi jack soldered too fast, no tin through hole, no flux used, some connectors would not have joint yet 7/ cannot have more, i'd better go to failarmy
I think maybe you skipped a step? Suddenly, at 12:44 at the bottom left by your thumb there is a green capacitor? another resistor and a couple orange jumper wires. I can't find anywhere in your videos what these are.

Actually not that I look at it again, there are two new capacitors. Been enjoying the tutorial so far but this is leaving me dead in my tracks. Did I miss a step? I'm pretty sure I didn't :-/
Where's the schematic?
Could you make a follow up on how to add voltage control capabilities? I'd like to be able to control this little thing from my Eurorack modular.

That's a good idea WRR. I'll consider it for a future project.
It would be cool to add CV to the controls using some DYI Vactrol's (Thanks !!! Look Mum no computer)
Hey there, thanks for that nice workshop. Its my first diy build so far but i managed to implement a toogle switch to swap between midi, pentatonic drone and logarithmic drone and added simple cv controll to the parameters. Even though my cv pitch control works reverse ( dont know why, but its a happy little accident). The only trouble i got now, is when i turn on the arppregiator of my microkorg and let it play. At some undefined point it just stop. As i switch between modes it catches up the midi again. (Dont know where the problem is, code is the same as yours, i just programmed the toogle to pin 12 and 13 to switch modes and added a led) But while Keyboard playing by Hand it works fine. Maybe some kind of information overflow in the arduino ? Do you got any thoughts on that ? And thanks again for your really nice-to-follow documentation. ✌
Hi ! Correct me if I'm wrong. Pin 2 at atmega chip is a digital pin 0 (RX) at Arduino UNO 3 board ? And as I understand after midi upgrade AUDUINO reacst only to MIDI notes and is no longer a standalone noise/sound generator ? and btw thank You for that great tutorial ! It;s gonna be a great addition to a live techno setup !

+booq Hi Booq. Yes, Pin 2 on the ATmega328 is digital Pin 0 on the Arduino UNO. And yes the synth will be silent until it gets a MIDI note input. Good luck with your build!

Notes and Volts Hi. Could you please include a note in the video to reflect that the device is silent until it gets a midi signal. I spent hours trying to find the problem when I first fired the board back up to make sure it worked. I didn't realise this was the case. From the comment section it looks like a LOT of people's problem may be the same as mine was. Thank you for all your hard work, it's really very appreciated. I just wondered could this tip save a lot of people some headaches ;)
Excellent!! thank you. I have a question, is it possible to add a signal input to this synthesizer?
Is it possible adding an input instead and plugging in drum triggers to make a simmons type drum brain?
Thanx for you videos. I'm looking forward to building two of these, one for me and one for my kid. I would like to add something to it, though - a rotary switch for selecting different scales for the center knob. But I have no clue how to do it :) Maybe something for a new tutorial? :)

Hello! Thanks for sharing this awesome project. Hate to ask the same question again and again, but as I understood everything will work with the Uno, I just need to re-trace the connections, as 328 have different pinout, and also do some code tweaking, according to the re-tracing? Is there any other things I should give attention to? Thank you!
works pretty well on an arduino nano. is there any chance of polyphony, or is it already pushing the arduino too much?
Does anyone know how i would change the pin that the arduino uses to receive midi signals? I'm using a Pro Trinket so pins 7 and 2 aren't avalible
Hi! Nice video, man! Can you please explain to me how/if I can change the pin numbers to the channel dip switch? Thank you a lot!
what is the total cost of this project up to this midi point? how much was spent total through all the other videos to make this final project?
hello my friend great video you have, can you make a video on delay rack mount for vocal, short story long thanks a mill .
this code does't work, unfortunately... could someone help pls?

Hi Johnny. First go back and double check all your connections. Look for bad solder joints and parts that may be in backwards. If everything looks right, start looking for bad parts. It will take some time but you will solve it. Troubleshooting is a valuable skill that all electronics enthusiasts need to learn. Good luck!

Thanks for the reply, I tried another round with the install and everything uploaded. Unfortunately a new issue. Once I power up, there is a tone present. No change with midi input or change to the knobs. I checked for bridged connections and replaced the optocoupler with same results. The MIDI output on the controller and the program are both set to 1. Any ideas on how to troubleshoot?
Hi, very cool project man! I want to build it in the next few week but I have a question, how can I connect a usb key to this midi synth? I search online some adaptor but i found only a one usb to two midi (like this www.strumentimusicali.net/product_info.php/products_id/30028/bespeco-bmusb100-interfaccia-midi-usb.html?gclid=CJ3qm5a579ECFWcq0wodaSEE1g) so, if 1 goes to the synth the other where it goes? It works also if 1 midi is disconnected? Help please! Sorry for my english and for my electronics knowledge ahah
