Great video! Thank you for your work you spent on the Ostman Solina, which I found to uninteresting in it's original state. Didn't even recognize it didn't have DIN MIDI. But the final game changer is the gate output. Together with EG, VCF and VCA, you get something Korg Poly-800-alike, which is not too bad considering the low cost and effort. The pinnacle would be an additional PWM CV output which doesn't have to be 1V/oct, just for the sake of brightening up the filter cutoff at the higher notes. But I can also implement that by chaining the string synth with a MIDI to CV interface. I have some assembler code to run on a little ATTiny85 with an optocoupler for MIDI and a pwm output with a plain passivce RC lowpass for the CV. PWM frequency is high enough so you get all the steep note changes without any unwanted portamento, which I would have expected from a circuit as simple as this. I can send it over, if you're interested.
Oh that's some really cool insight. I would be really interested in adding an EG but I'm new to DIY synths and I couldn't find any that would run on +9V or +5V (edit: single supply). Do you know any?
@@SaltaSoles TH-cam deleted the Link I posted in response. Google for Schmitzbits ADSR. The second design with the 555 timer should work on single supply as well since the signal voltage buffered by the opamp doesn't go below 0V anyway.
@@zerstaerker ohh thank you very much. Those projects seem simple enough for me to try. Sorry for asking over and over but I'm still not familiar with opamps. Could I use the same schematic with the same opamp (TL081), using the ground instead of the negative, or should I change to another opamp design altogether? For instance, an Lm358 or alike?
Berry nice. Little mistake on your version of the filter schematic. The 10k resistor after the dual pot should connect to the wiper of the second pot in the dual pot.
@@LAURISDIYCHANNELTV Anyhow - that's a pretty fun filter. A good find - and thanks to Leploop for publishing their design. I built the filter to add to my DIY modular. I also added a diy dual vactrol to the cut-off pot so I could have VC on the cutoff. Niiice.
The synth + filter sound really good. Here's a little rookie mistake I made, in case someone else wants to build this: contrary to other arduino synths out there, the original code apparently has a few switches for midi channel selection. If you don't connect anything, like in the video, the synth will listen to midi channel 1 only. Be careful not to accidentally change the midi channel in your midi controller (it happened to me), since only midi channel 1 will actually work.
It would be nice to modify the code so that multiple Arduinos could be stacked, since a big (BIG) part of what makes true string synths (and divide down transistor organs) musically useful is unlimited polyphony. Being able to scale this project up to at least 16-24 voices would at least get you in the ballpark. As it is it sounds fantastic, though. It's abig improvement on the original project and could be the basis of a really handy drone synth.
I'd strongly recommend to use the gate output with an envelope and add a AS3320 based filter to it. You won't need a VCA since the "oscillator section" comes with it's own volume control. But DUDE that 3320 filter sounds super fat with resonance turned all to zero and giving it an slower attack brass sound like envelope. You really get some prophet vibes. How difficult could it be to change the code from driving a PWM audio output to driving a dedicated DAC chip?
Yeah ive used this with my SSM filter, that has a similar sound to a CEM, and it sounds very pleasant and brassy indeed! I’m sorry but i have no idea how to modify the code, i know very little about that stuff! 🙈
Maybe aliasing on the higher notes, could you increase the internal clock rate or something? Sounds great lower down though! Also 6 voices would be nice, is that a limitation of the Arduino's processing power? I know nothing about that, but cool project anyway. Nice work!
I'm not a specialist but after having a glance at the code, it looks like the pitch is defined by initialising the internal registers/timers of the micro-controller, I don't see a simple way to modify it and doubt it can be possible keeping this architecture.
I dont know a whole lot about coding, but im pretty sure there is no way to run VSTs on arduinos, because the hardware just isnt capable! You could build a dedicated midi controller to use with your DAW and the VST but thats about it i think!
niiiiice! I've tried to build it on Arduino Uno, but it doesn't work! The RX led doesn't even blink :( I've replaced the octocoupler's diode with a led to see if there is signal from my keyboard at that one is fine... Would you have an idea about what could be wrong? Thanks a lot!
I’m not sure what the problem could be! Make sure your pins are correct, as the UNO has a completely different pinout. And remember the output pin needs to be a PWM pin.
Oh and make sure your keyboard is on the correct midi channel! If youre not using switches to change the channel, it should be channel 1, if i remember correctly
When the ensemble is turned up I wonder whether the distortion is simply due to clipping. The summ of the signals gets too large (positive or negative) and therefor the amplitude to the DAC clips at the maximum integer value. By keeping the amplitude at bay, you might be able to prevent the clipping from happening.
Fuck yeah dude I looked this up years ago but jan's version was with a midi keyboard and it was too scary for me to try. I'll definitely try this one it looks simple af
The intro jam absolutely enthralled me to the point I am just about to finish my own DIY solina using your code and schematics. Today I received the last batch of components I needed. One quick question here: do you know any EG schematics that could run on the same voltage of this synth? A single supply +9v also works since I'm using a 9v power supply with a 7805 regulator to power up the Arduino and the filter anyway. However all the projects I found regarding EG required dual power supplies unfortunately. Any insight would be really nice.
@@SaltaSoles yeah for most EG circuits online you do need a bipolar power supply, but i’ve used a simple AR envelope design by Synthnerd a couple of times and its awesome, if an AR envelope is enough! I’ve used it with 12V DC and it should work fine with a lesser or greater voltages as well. You can google ”synthnerd AR envelope using op amps” and you should find the website for it!
@@LAURISDIYCHANNELTV thanks a ton! Will definitely check it out. Also yesterday I was prototyping the circuit with your code (without adding the pots nor the filter yet, just the optocoupler and the output circuit in the Arduino schematic you shared) and for whatever reason I couldn't manage to make it sound. When I load other arduino based synth sketches (like, the Helios One) I managed to pull out some sounds. But not with your schematics. It's very odd. Helios uses a different PWM pinfor the output, but otherwise I used the same schematics as yours when I loaded the sketch. Any ideas on how to troubleshoot it? [EDIT: I figured it out. Mind the midi channels of your controller! Will post in the general comments just in case someone else falls for the same rookie mistake as I did]
Hi, this is awesome indeed. 1 question though. Why isn't there some DAC chip? I recently build a midi to CV converter and this need a DAC to convert midi notes to voltages. Why is this different?
@@MJLouer the code uses the PWM output of the arduino, so the output is just +5V pulse wave with very fast varying pulse widths! This makes the circuit super simple as you dont need a DAC but also the output is nowhere as clean and nice as you can get with a DAC. At least this is my understanding of the subject
I tried to present the project, it works poorly for me, the sound on your video is also not so beautiful. Question, why do you have 6 knobs in your synthesizer, and 5 in the circuit?
Yeah the sound is definitely not “beautiful”, its supposed to be a bit glitchy and dirty! The 6th knob is just the pitch control i tried to get working but failed! So its not connected to anything
Oh true, i dont mention this in the video! I’m using a 5V voltage regulator, but i believe the arduino nano boards do have a built in regulator. So you connect 12V to the voltage input and you can take the 5V going to the potentiometers from the boards 5V output pin. At least thats how i think it works! I always use an external regulator cause i trust them more then the cheapo arduino clones im using + for some reason its clearer for my brain to build circuits this way!
Mine is permamently set to channel 1, but if i remember correctly, the code includes a way to set the midi channel. You need 4 on/off switches that connect 5V to 4 digital pins of the arduino and the combination of the switches chooses the channel. I cant remember what the pin numbers are, but you should find that info in the code
@@LAURISDIYCHANNELTV Is there any discord ? I cant get it work. Ive uploaded the sketch on the arduino, on breadboard i only have the output A5 for the envelope control, I have the midi connected to the 6N137, and it works because I used it for another midi IN project for a volca, I only breadboarded the resistor and the two caps at the output pin D11. I have connected the midi to my beatstep pro and see taht the RX led from te arduino flashes... andd it does not sound anything... May in the code the pins be set different as per your schematic? super regards :)
I guess you could use cv instead of the potentiometers or combine the two with a couple of resistors! But i think you should make some sort of a diode clamping protection so you dont accidentaly connect negative voltages or more than 5V to the analog inputs of the arduino and fry it!
You can do a crude voltage control for the filter using 2 vactrols. The resistor sides of the vactrols should be connected to the pins of the dual pot (cutoff). And the led sides should be connected to ground and CV input with a 1k resistor. Its hard to explain in writing without it sounding complicated hahah but its simple. You can google similar circuits and look at the schematics. I used vactrols the same way in my cd4069 filter, that i have a video about on my channel! Hope that helps ✌️
Hi all. I build this and works, but the 12db filter is behaving strangely. It works but when i press a key i hear some sort small pauze before hearing the note. It sounds a bit like that the transistor startup by each key ptessing. Its gets worse when pressing 3 keys. Ik checked the schematic multiple times but all seems good. Maybe this behaviour is caused by the double decoupling. 1 from the solina synths output (1k, 10uf cap), and 2nd the input resistor and cap. To me it seems redundant? Or do i just connect the output of the solina to the base of the input transistor of the filter? Any advice very appreciated.
I'm having the exact same issue. Like a gate that slowly opens after pressing a key. My audio interface also clips when I press a key, but there is no audible signal at first. This did go away when the middle wire to the 10k resonance potentiometer accidentally broke off, wich also boosted the audio signal tenfold. Not a great sollution, because the filter did not work as intended anymore. I tried plugging the synth into my monotron, and the monotron filter reacts the same. Seems as if the issue is caused by the synth circuit, but I have no clue yet where.
