Loved your last little jam session!! Awesome. I"m planning to build one as I've got most of the parts kicking around. I like your presentation style so please keep your videos coming.
Great stuff! Sorry I missed it live. I think adding a midi out and thru would help keep the notes from resetting overtime they are triggered. Also, you'd be able to capture your pots parameters for refinement.
First up - Notes and Volts totally rocks 🎹🔌🎸= 😊 I'm really getting a lot out of this revisit build of the granular synth on a Nano board. I had tried out the 5 knob with a nano and had heaps of fun. Including removing the spring from a gamepad thumbstick for x-y control to replace a pair of the pots - I only did one because desoldering the thumbstick from it's pcb totally warped part of the plastic assembly and required a pal with more skills than me to salvage - he did that with snips, bullnose pliers and a tiny piece of guitar string! Anyway's at first I thought the clip was a bit longwinded - but it's definately not at all. When something unexpected happens, you do what I am starting to realise is very, very important - rechecking, debugging and applying some critical thinking. I've been diy'ing simple Eurorack modules on breadboard, then veroboard if I like them, for a couple of months now. It's been great fun and I recently discovered Arduino too. The biggest thing that I've found that can kill the fun (Arduino or otherwise) is getting disheartened when a project you got from internet doesn't work first time. My experience so far is that 99% of the time I've missed a step, a wrongly placed (or even forgotten) a component, loaded code to an unplugged Nano 😜 etc. So attempting to understand what's actually going on between the wires has been pretty helpful. This video has been great for me - and I'm looking forward to adding MIDI. Cheers 😎
The first Arduino synth project works fine but i have months fighting with the nano, just don't work, any suggestión?... By the way your channel si osom
I know I'm 3 years late, but if you ever see this, can I use another audio source to replace the MIDI? lets say if I have a mic up there or an mp3 player, can I still use the synth to manipulate sound?
@@DustinjBailey You know what.. I think we could. if you see @40:01 when he was about to add the MIDI jack he only used 2 pins of 5 in the jack.... those are the audio signal pins.... it's a sound signal, the circuit won't know if it was coming from a MIDI or a mic or even a guitar it only know that it should expect an audio wave... that seems logical to me.
Hi, Notes and Voltes. Could you kindly share the schematic and if it's possible to make a list of the items that you used to make that project? Cheers from Portugal :)
At 51:30 you set dipswatchinstalled, you have it set to true, but you have ALL of the switches code commented out // So why are you getting sound out, and what do they do if you UN-comment them out in the code from the switches?
Hi, thank you for sharing this. Im a student in visual communikation in pforzheim germany, and i want to use the auduino midi in my studentproject. The old school auduino works fine, but the midi chanal makes problems, and i dont know why. I build it with an arduino UNO, i think the problems are the pin numbers on the different arduinos, where must i connect the pin 6 from optokoppler to my arduino UNO? on pin 0(RX) or pin 1(TX). what must i change in the sketch? define midichanal on pin 0? On another Video, Build the Auduino Granular Synth - MIDI Upgrade, on your Notes and Volts website you use other resistors like in the schematic from this Video, witch resistors should i take? maybe this is the mistake, what do i wrong? :( . Iwant to create a PCB Synth. HELP.
Thanks for posting these! I love your videos. I'm not sure if you'd know the answer to this, but both times I've built this circuit it's lasted for a few minutes, then the arduino board dies. There's no smoke/pops involved, and my circuit isn't in an enclosure. Any chance you'd know?
I haven't measure that yet, I'm currently awaiting to get some more boards in the mail! I've just been powering it via USB through my desktop computer. I've built a number of Arduino Synthesizers now (other than this one) and I've never had it happened to me before! I must be doing something strange lol. Anyways, thanks again!
thats so cool... Like i´m playing Saxophone i would like to build a Windcontroller like a EWI Akai but the Problem ist... Buttons are not working like a Piano.... means Butten 1 and button 2 and button 3 = a note ... and whats about note of.... if one day you build a Windcontroller ..that would be cooooooolllll.... greatings from germany and sorry for my english
Interesting! i'd like to watch these live sometimes but since the time zone differences i'm guessing that's not going to happen soon ;) Great videos and well explained. Thanks!
Yes. I use a MOTU - MIDI Express 128 but any Midi interface or audio interface with a midi jack will do. Or just plug it into a Midi controller and play it live. As long as you have something with a 5-pin midi out, you are good.
Hi Dave, Love your video's. I made the Uno and Nano version, but with both I can't get midi to work. When sending midi (I tried all channels), I read about 0.02-0.03 volt on the midi side. But no changes in voltage on the other side. 4.97-4.98v when sending and not sending any midi. Should there be? Could it be I'm using the the wrong 6N138's. I got these on Amazon: 6N138-ISO Optocoupler THT Channels1 Out isolation amplifier DIP8 6N138 ISOCOM I'm gonna try some basic midi tutorials on a breadboard to see if that's working.
Hi Ronald. Sorry your having trouble. You may have a bad 138. I have found a couple myself. Definitely do a simple test circuit to see if you can get any signal as a start.
Hi Dave. Problem solved. I build a basic midi circuit and fell in love with the Arduino possibilities of midi in/out circuits. ;-) . Because both of my projects were not working I expected some unexplainable problem but in the end (in the case of the Nano) I just switched pin 4/5 of the midi connector :-(. Not sure what is the issue with the Uno version but I use that one a a noise box now.
Hello, I would ask somenthing : When I tried to use the program that you post in the comment , It had an error : "tccr2a was not decleared in this scope". Can you tell me how to solve it please?
Very good INFO , thank you for that! questions: you connected a Midi interface A programa/software, (no free software?) maybe somewhere also find a free midi software? hope there is a sequel, with .... a free midi software ??? Kind regards from the Netherlands! Rob.
Thank you for your reply, I have no knowledge of MIDI and music.(Also software is not my strongest point) but hoped there was a small software which can do the job just for fun a little play with it. messing with Arduino I really like, and your Projeckt sounds good! Friendly greetings from the location Rotterdam! Rob.
HI Branko. The 6N137 is requires a change to the circuit and is not directly compatible. Google search 'Midi 6N137' and you should find some common circuits.

Why do I see just random pictures instead of the video? If I hover my mouse over the timeline I can see the actual video, this is confusing as hell lol
@@SpaceDanceOfficial Hi, If you use another browser (other than chrome) then it should work. thats how I got it fixed. I just used edge instead of chrome.
That's true! I think music and math use many of the same mental processes. Also, When I was young, I got really into guitar but couldn't afford much gear. Once I figured out you could build you own overdrive box for about 1/10th the price - I was hooked!
Where do i get Arduino MIDI Library v4.2 or later? In fact why don't you tell us where to get it? You never mention it. why assume things? Not that I'm likely to get an answer, looking at the questions below NONE are answered.
Loved your last little jam session!! Awesome. I"m planning to build one as I've got most of the parts kicking around. I like your presentation style so please keep your videos coming.
Dave, your solo improvisation over the backing track near the end of the video was real trippy, man! Love your work!
Thanks chapogee!
The nano is producing that audio output ? Very impressive
Love the on the fly multicamera work with your Auduino in the upper left.

just recieved all the parts for this build...cant wait to put it together
Hi! Noob here, any chance you can post a list of the parts?
Nice mix of theory and practice!

Have you ever come across CV control so you could use it with modular - or is that too much for the Nano
Entertaining and educational, as always. Thank you!

Great video, Very educational. Wanted to ask where I can find the parts list for this synth.
i have just discovered your channel! Its great! just what i needed. I just got stocked with arduinos and cables... Im ready to follow you master :)
LOL! Thanks Pablo! Welcome aboard :)
This is really amazing! Thanks!
Is there a list of the components in a online store somewhere?

Hi. Great project. I just finished building this on a breadboard, so now it is time to order some components and build it into a box :)
Awesome Martin! Nice work :)
Thanks
Is there a way to plug a midi controller via USB? My midi keyboard does not have a midi port.
will the code also work for an arduino UNO?
Yes, it will. UNOs are pretty cumbersome to stuff into a box though.
At 51:30 you set dipswatchinstalled, you have it set to true, but you have ALL of the switches code commented out //
So why are you getting sound out, and what do they do if you UN-comment them out in the code from the switches?
Buenas tardes, gracias por el video. Una pregunta, donde consigo esos modulos osciladores o filtros que tienes, que pone arduino?

Great show again. Is it possible that you can share the KiCad file for the schematic?
What model of pots are you using? I can not find any parts list.
can you trade out the midi and or add a 1/4 inch in...for guitar or and instrument input...use it as a realtime effect?

Hi JR. That's weird. What are you powering the board with? If it's an adaptor, what voltage are you measuring at the Vin pin?
I haven't measure that yet, I'm currently awaiting to get some more boards in the mail! I've just been powering it via USB through my desktop computer.

Watch out getting a 5V Arduino! There are also 3.3V Arduinos, which will die when putting 5V on...
sam reccomended i come and see this site...im not dissapointed.
I´ve build it twice, one with Arduino nano and one with Arduino UNO and everytime it doesnt work , doublechecked everything :(

Yes. I use a MOTU - MIDI Express 128 but any Midi interface or audio interface with a midi jack will do. Or just plug it into a Midi controller and play it live. As long as you have something with a 5-pin midi out, you are good.
Is it possible to do it with a Jetson Nano?
Dave, I noticed that you used 10K pots in this project as opposed to the 5k pots in the original granular synth project. Any comment?
HI David. I switched to 10K Pots because they are more common and easier to find in stores. Either 5K or 10K will work in the circuit without issue.
Thanks for taking the time to answer. I really enjoy your projects and presentations. Well done!

Hi Luca. What Arduino board are you using?
I'm using Arduino micro board
This won't work with the Micro. It needs a 328P based board (Nano or Uno)
Ok, thanks for the advice !
Notes and Volts Sweeet! That means I can use the Pro Mini!
What is the part number on the linear pots?
Very good INFO , thank you for that!
questions:
you connected a Midi interface A programa/software, (no free software?)
maybe somewhere also find a free midi software?
hope there is a sequel, with .... a free midi software ???
Kind regards from the Netherlands!
Rob.
Hi Rob. You can use any sequencer or DAW software (or hardware) that outputs 5-pin Midi. You don't have to use Ableton.
Thank you for your reply,

Is it only the MIDI controller ?
Hi mrstanlez. The Auduino generates its own sound.
@@NotesAndVolts Thank you. I was in thinking that only you say about midi controller with some pots.
WOW!!!!!!
So could you plug in a midi keyboard to control that?
Hi Lee. Yes, with a 5-pin Midi cable.
Ok cool! so it could basically be used to turn a simple midi keyboard into a basic synthesizer?
Yes, that is doable.
hi dave can i do'it with a arduino uno???

have you found out?
In a previous video he says 33nf. It doesn't have to be exact, for it determines how much information will be removed from the signal
