This is my take on Audiuno by @NotesAndVolts. I added CV inputs to all controls. It still needs some tweaks to make it respond better, but I'll save those for the next version!

Impressive. I bought a nano to do something similar (sampler), but I haven't a clue where to start except follow other people's projects. You are obviously far more accomplished and the result sounds really good.

This sounds really good! Hope to see more of these in the future! Great video
-
Looks and sounds superb 👍GREAT job
-
Seriously brilliant work on this Benjie !
-
Great work! Sounds great!
-
nice! great technique to save time with front panel design. awesome.
-
cool jam! I really enjoyed it.
-
Bravo .. this is awesome 👏
-
Amazing!

Thanks for your contribution to the Granular Synth community 🎶🌎☮❤ I don't have the skills, but would be great if someone could turn this into a PCB file with gerber files, so we could send out to have PCB made. Maybe do a batch purchase. Best wishes for your continued success 🔥

Astig! buti nakita ko tong channel mo 🙌

woow ..very very cool
-
Lovely. It's like the first words from a newborn. ;-)
-
amazing m8!
-
That turned out really nice dude!
-
wow!!! nice sound. Are you by any chance going to make the code and schematics available, please? I really would like to build one for myself. Thank you and VERY WELL DONE!!!!! :)

Hi Benji, First off, let me say thank you for posting your builds online, and especially for offering the files and BOM’s as well. Very generous! Wanted to ask about the soundtrack of the video you made for the GranulArduino. Was this all recorded from the GranulArduino? And if so, how did you process it? Clearly reverb, but anything else? It sounds great! And you are using a sequencer? It wasn’t clear to me how the two oscillators interact, the timbre of the sound does vary (and sounds great) but I can’t really tell if there are two separate voices or if one voice modulates the other? Anyway, I am teaching myself building electronic stuff as well, and this looks like a great project with a very rewarding result! Am very interested in your idea of a sample playback device, have you developed this idea any more?

Great job for a nice toy ! Just a simple silly question, the leds you added are directly from pins 2, 4, 9 & 12 through resistors ?

This seems like a fantastic project Benjie, but I'm not sure I understand what a granular module does in a modular synth setup. Does it use a sampled sound and take grains from that, or is it sampling grains from a VCO as input? What is actually happening "under the hood"? What I do know, is that I would like to make one 😆

Excelente adaptação. Já construi tres unidades baseadas em notes and volts e fiquei feliz em encontrar a sua versão CV. É possível não utilizar o ADC e ter algum bom resultado? No Brasil é dificil encontrar esse componente e a exportação fica ridículamente cara por causa do frete e impostos. Agradeço se puder me ajudar com essa questão. Boa sorte e sucesso.
