My first venture into the teensy audio library! This is a polyphonic synthesizer with various controls. Learn about Teensy audio library: www.pjrc.com/t... Code: github.com/ote...
🤯 Been developing a T3.6/SGTL5000 quad audio shield for a laser waverfom generator/control desk. Just discovered the Teensy Synth DIY kit and ordered the front panel & PCB, but I'll use my preferred LED buttons and rotary encoders, instead. Love your multicolored cubical buttons, BTW. Are those available online or your own 3D printed caps? Wasn't really interested in the Teensy Synth's code, then I stumbled upon yours, which is exactly what I've been working with from the ground up, with the pjrc development tool.. IOW, thanks to your sharing your sketch, you've saved me months of frustrating coding. 🙏 With your foundation, I can easily duplicate and customize it for my specific needs, such as a 5 channel audio output. 2 Teensy tech scores in one day! Woohoo! Thank you for making my week!😎
@@otemrellik Thanks for your reply. Yes, after posting my comment, I discovered your link to sparkfun and found both, the RGB buttons and RGB pushbutton rotary encoders. They've already been ordered and everything should arrive this week. So, I'm anxiously waiting to get started on the laser control desk. IOW, it wasn't a double score, but a trifecta for that day. Thanks! BTW, your more developed code is transferring very nicely into mine, requiring little more than copy & paste, plus changing the declared references. That will save me ~ a month of frustrating coding. Awesome! 😎
if i could like it again i would...i am trying to make a version of this with pure data...virtual at the moment, but hopefully i can build it in real life too.
Hey bro, I been binge watching all of your videos lol. I love the little synth machines that you build. I've got 3 Pocket Operators myself and I'm starting to get into circuit bending old electronics and toys. I'm no expert by any means, but I am really wanting to attempt something like this. Unfortunately, I am kind of living off my stimulus check and don't have a lot of money to spend. Would I be able to build something like this using Teensy on a budget? I actually worked for a wire harness company for years, so soldering and crimping terminals is second nature. I can read blueprints and wire schematics for pin out connections, etc. I actually have bad anxiety, so my hands shake a lot and makes it annoying when trying to do anything with your fingers or hands, y'know.... like soldering delicate PCB boards lol
I altered your code to use MIDI. It took a long time to figure it out and much of your original code was butchered up, but I wouldn't have gotten a head start in making a synth without your code to begin with. Here's most of your synth controlled via MIDI ruclips.net/video/fVdPEy9sTUk/видео.html I made a GUI to control parameters and allow a connection of a MIDI keyboard. It's still in the early stages of coding.. there's some bugs to clear up.. I think it's the formulations changed from 10 bit resolution to 7 bit MIDI resolution (128 max vs. 1023 for your analog pots).
Good to know. I've been diving into understanding the circuitry of hardware synths this year and this has me feeling compelled to finally explore the world of Arduino. Thanks for making the code available!
Hi otemrellik, congratulation! This is a very cool thing. Wonderful work. I´m using a novation impulse 61with several knobs, faders and encoders and I like to use your synth with it. But I miss a MIDI-IN and the possibility to store sounds. Are there further plans?
this is awesome. i'm hoping to make something similar. a few questions though. what value pots did you use? also would it be possible to give us a rough idea of how this is wired internally. i have read the code but i cant quite work out the whole thing. even just a photo of the inside would be greatly appreciated by many. thanks
two questions if you don’t mind: Is the mono amp just being used for the speaker? in other words is the audio out that you use in the video stereo? did you use SF’s button pads? most code i see for that is based on using them as a matrix, which is absent from yours? not sure i understand it. thanks for any help you’re willing to offer.
As far as I remember the amp was just to drive the speaker. I probably used the teensy audio board for this so that does have a headphone out and left right line level out's as well. I did use the sparkfun button pads. I think it was two sets of the smaller 4 button boards. I don't think those are setup as a matrix. Sorry this project is pretty old and has been cannibalized for parts many years ago so I'm just going off my memory.
@@otemrellik no worries man, thanks for replying at all. i'm going to try and jump back into the project and from what I last remember, it seems that it wasn't setup as a matrix. i'll keep toying around. looking forward to seeing your new creations!
how long have you been making these? I have a couple ideas for some goofy synths id like to try out, but Im wondering if the learning curve is too steep
I think I had been playing around with arduino for a couple years making midi controllers before I built this project. I started messing with arduino without any education about coding. You can do it.
hey, I'm working on my own 16 button midi controller like the spectra. I was wondering is there any way to set up the arcade buttons with the teensy 2.0 without using a multiplexer (mainly how to connect the buttons to the board)? There are no LED, potentiometers, etc.. just buttons.
@@otemrellik I ended up working on a midi mixer board designed around the Voicemeeter GUI. I figured that I would get more acquainted with the Arduino platform before jumping into the audio side with teensy. Your synths are inspiring, dude. I'm excited to see what you come up with next~
Two tracks: 1- Learn the components of a synthesizer: VCO, envelopes, filters etc. You can play with PureData to simulate them all. 2- Learn Teensy boards or other microcontrollers.
otemrellik btw on another note! are u for hire? or do you do any consulting etc? my friends and I have a very ambitious project in the making and we sure could use some guidance 😅 haha
Dude that's a pretty cool little synth. I like the lo-fi gritty sounds it makes. Looking forward to seeing your other projects, keep it up!
Wow I'm glad I found you. Thanks so much for documenting this.
That's an awesome work! I'm building my synth with the Teensy library in this is really inspiring.
Very cool, I like the simple interface with the preset scale. I can imagine this instrument being a lot of fun to play.
You sir are a BOSS lv wizard! i bow before the might of your techno wizardry !
nice work OTEM ! inspiring as always.
Sounds so cool. So impressed u can remember all these settings.
Love this! I'm just starting out with Teensy and this is very inspiring
Wow....really cool. It would be so cool to see the wave lengths on an o-scope. As you play it.
Nice job on the enclosure and knobs! Makes wish I had a 3d-printer.
This little machine is awesome. Well done on the build. Also......................KITTY!!!
You really should sell these
damn dude your a electronic synth genius! Right on!
Hey, I stumbled upon your GitHub and saw the teensypolysynth and looked for it here. Pretty amazing. Good job!!
Could you provide schematics please?
Really want to build something like this, but I'm not sure where to start. Love how it feels built to just explore and experiment with patch sounds.
This thing is amazing!
HOLY SHIT THIS LOOKS SO GOOD I NEED 10
Nice work!Sounds rich

Np! The push buttons were from sparkfun I think. All the slider and pot knobs were 3d printed but I don't remember them turning out super great, haha.

Dude! This is awesome!!
Awesome!!! Great work!
Nice job Dude.
Add MIDI-in and you have a winner!
put a LiPo and a charging board so you can recharge it with the USB port
So cool!
you are amazing.
i would buy
subscribed. this is dope.
Impressive!!!
Hi! Nice!
I plan to build a synth - would it be possible to show some pics of the circuit. That could help me.
Thank you
Hey, sorry I never drew a circuit for this.
I would buy anything you made

Yeah, you should be able to build something like this pretty cheap. I'd start out with just a teensy and some pots/buttons and just experiment a bit.
I altered your code to use MIDI.

Can you share complete plans?? would love to replicate this
I love everything about this. Plans to share further details of the build? Schematics?
Thanks! I don't have schematics but if you look at the code you can figure out the pin connections.
Good to know. I've been diving into understanding the circuitry of hardware synths this year and this has me feeling compelled to finally explore the world of Arduino. Thanks for making the code available!
Id buy a kit
i want to chew so much on these buttons
Hi otemrellik,
congratulation! This is a very cool thing. Wonderful work.

This project is 4 years old. Check my recent videos for newer projects.
Love this! Approximate cost? (in the middle of the video, in case you say it at the end)
this is awesome. i'm hoping to make something similar. a few questions though. what value pots did you use? also would it be possible to give us a rough idea of how this is wired internally. i have read the code but i cant quite work out the whole thing. even just a photo of the inside would be greatly appreciated by many. thanks
10k pots. Sorry I can't provide much on the wiring. I don't really have the time to pop this guy open or make a schematic.
Interesting stuff! Although I'm not a "digital guy".
which amplifier do you use please 😊 and why do you use a multiplexer ? thank you and Amazing project
very cool. slick looking synth. Did you make the box itself or was it something you bought?
I printed it. Here is the design:

Hi, a great project. Can I ask you where you got the key pads from?

Sorry, I don't have a schematic.
Great achievement! I'd like to know how many keys can you play simultaneously? :)
Eight.
How would one go about attaching a TFT display to this board for showing a bar graph?

I think I had been playing around with arduino for a couple years making midi controllers before I built this project. I started messing with arduino without any education about coding. You can do it.
Is there a MIDI library function that can be incorporated into the build?
love your video..you still have this? maybe you sell to me..i would love to buy this from you...
I don't. This was cannibalized for parts many years ago.

TheNullObjects If you use the new teensy3.5 or 3.6 you don't need sound adapter or mux.
Is there anywhere that I can find your schematic for the hardware? I'm new and learning. This would be the perfect project for me to get into teensy.
Sorry, I never made a schematic for this. If you are just getting started, check out the Teensy Audio Library examples.
@@otemrellik I ended up working on a midi mixer board designed around the Voicemeeter GUI. I figured that I would get more acquainted with the Arduino platform before jumping into the audio side with teensy. Your synths are inspiring, dude. I'm excited to see what you come up with next~
this is so cool! where did you get the knobs from?
I printed them.
Dude, what did you go to school for?
How you make switch caps? TPU print or?
I think these were just abs plastic.
2:08
How did you play the synth without computer?
Do you mind if I ask what rating of pots you used on this? Are they the same as your looper thingy (10k)?
I don't really remember but am almost certain they were 10k.
What does it sound like? THE FUTURE!
Do you have the teensy audio design layout that you used for this synth? Or is that all taken care of in the github code?
you can import the code from github into the design editor to see how everything is patched.
Hi, may I ask what values you used for the pots and sliders? = )
10k
Is there a guide ?
No, sorry.
how can i get into making these devices? where to start?
Two tracks: 1- Learn the components of a synthesizer: VCO, envelopes, filters etc. You can play with PureData to simulate them all. 2- Learn Teensy boards or other microcontrollers.
i appreciate your reply thank you my brother
Where do you get those glowy buttons?!
www.sparkfun.com/products/7835
are there any tutorials showing how to easily make a midi controller using teensy?
little-scale.blogspot.com/2017/03/teensy-36-basics-send-midi-continuous.html
oh man... this looks so complicated :S
It's not! Just take it one step at at time.
otemrellik ok haha thanks I will :))
otemrellik btw on another note! are u for hire? or do you do any consulting etc? my friends and I have a very ambitious project in the making and we sure could use some guidance 😅
haha
can i use a raspberry B ?
Not for this project. This uses the teensy audio library.
for rpi you can run headless puredata patches and have the same result but a bit more work . The teensy looks quite faster to build
