hi there Ben! I've built a simple but nice monosynth with CMOS oscillators, one of them being your very own miniOSC (you cant take a look at it on my channel), and after a while I got a pair of CEM3340s, very hard to find where I live. so, a second monosynth is on the way. but this time I want to make it midi controlled, to get a decent tracking (and your module is a solid candidate). my question is: is it possible to add a glide - portamento to this midi2cv converter? thanks a lot in advance. keep up your excellent work!
Hi habbi! Thank you very much for the kind words! I'm pretty sure you could add a portamento circuit at the end of the CV output. Something like this (unverified) should do the trick: ua726.co.uk/2011/05/22/really-simple-portamentoslide-circuit/ Thanks for bringing it up, too! I'll consider it when I design the Eurorack PCB version.
@@benjiaomodularHello again. I seem to be having some trouble getting this going. I've gone off your schematic you supply in the link (thank you for that). I can see the RX led on the arduino nano react as expected with note on off information. The CLOCK (& GATE & TRIG) LEDs don't react to anything at all. I would expect the CLOCK led to be flashing to the project BPM of my DAW (cubase) where I'm outputting the MIDI channel from (Channel 1), but I get nothing. I get no changes in voltage on a DMM when sending pitch bend or mod wheel info to the circuit. I'm using Elkayem's code with no changes. After a while, I also see the TX LED flash as well as the RX LED, where I'm pretty sure it should only be the RX? I would so really appreciate any info you might be able to shed on this! I feel like I'm missing something which may be obvious but just don't know. Could it be the midi library version or anything like that?
Ok. It appears I can receive MIDI from a keyboard, no problem. I can read voltages and all expected information, but it appears the problem is when I try to send the midi from my DAW. I so far can't figure that out.
@@-______-______- hey! I haven't tried using mine with a DAW, but are you by any chance trying to use it via USB? Because I don't think that'll work with Nano without extra circuitry
Great explanation. I wish someone would do a full build video.
Your synth is looking so nice! really loving the modules you've built :D
heyyyy. thanks dave! 🙌🙌🙌
This is brilliant! As is your DIY modular synth. Very impressive!
thank you very much! 🙏
Great video Benjie, it's just what I was looking for, I'll give it a try. Thanks.
Thank you very much! Let me know how it goes. ☺
@@benjiaomodular Will do Benjie, thanks.
thanks for this bro...
Maraming salamat din! Tamang video manual lang. 😁
perfect explanation.
Thanks, Markus! 🙏
Great video. I need to make one for my system. Good explanation on how midi works. 😃
Thanks, man. Do it!! I've yet to do a video on my entire system as well. 😅
I did the case still need to do the circuits lol its on the back burner. Lol @benjiaomodular
nice bro!! :)
Salamat!! :D

@@benjiaomodular yeaaahh thanks a lot! this is exactly what i was searching for! I can even try it on my mk1. thanks again! you da man!
@@habbi1974 Perfect. Good luck with that build!
May I ask, did you use the exact code included in Elkayem’s design?
yup! pretty much

@@benjiaomodular no. Not usb. Over serial.
did you consider PWM instead of DACs?
TBH, i went with this route because it was the one i had enough references for. Will that give enough resolution for v/oct scaling? 🤔
@@benjiaomodular yes, with clever scaling even a Tiny85 can do enough to be precise
That sounds great! I'll add that to my list of things to try. Thanks for the suggestion!
