Hey ! Just finished a MIDI to CV box. (I closed it and it is still working, happy days !). I used info and schematic present on this topic. > [@Arduino Nano Midi?](https://lookmumnocomputer.discourse.group/t/arduino-nano-midi/4582/30): > > Many many thanks for posting this (and of course for sharing it). I was making the MIDI to CV from Elkayem but nothing was working. Then, funny part, i realised that the LEDs were flashing at the correct tempo or gates every time i was switching it off. What made it go from not working to “working as expected” is the pullup resistor. 500r didn’t work for me. I am using 5k and it works great. (Also works without any btw) Posting this in case someone follows Elkayem schematic and ran in some i… ![16447643290805375250584816372115](https://global.discourse-cdn.com/free1/uploads/lookmumnocomputer/original/3X/5/8/5838ab97be67e4795d49f18c93cf7475df28b3d7.jpeg) I have a project coming. I want to build a DFAM clone (without the patch bay). I opted for 2 AS3340 VCO, MS20 style filter (easy HF-LF option) dual VCA from Sam and 3 AD-AR enveloppe generator and a distortion. I found the arduino sequencer from @analogoutput that would add a nice twist to it with the different pattern length and the random option. Here is the case (empty for now) ![20220130_202356](https://global.discourse-cdn.com/free1/uploads/lookmumnocomputer/original/3X/d/6/d6dee2b461f3fb00a9752fa1f34073f9da15c333.jpeg) ![20220207_223136](https://global.discourse-cdn.com/free1/uploads/lookmumnocomputer/original/3X/7/d/7d95f1f2d96d78d9c5e67c3b6fbf92c7b137a4da.jpeg) Back in many weeks i guess 😅 --- _[View the full topic](https://lookmumnocomputer.discourse.group/t/my-build-progress/345)._
