The circuit sounds really good. I love the color, it sounds much more lively then the noise based circuits. Nice work! 👏

[@LAURISDIYCHANNELTV]

This is awesome! I’m also building a hihat synth with the 40106, and this gives me the inspiration to get back to it! 😍

[@SkullDraizer]

I've had the DR-110 schematics for years intending to build some modules from it. You actually did it. Great work!

[@xavierayayaell546]

I made this and the switching noise coming from the 40106 is absolutely insane... No amount of decoupling can tame it.

[@HAGIWO]

Try tuning the limit resistor on the VCC of the 40106.
Looking at Roland's original circuit diagrams, it’s clear they put a lot of effort into noise reduction.

This system keeps getting better and better
Keep it up!

Super slick! I might try and see if I can make a 1u tile layout for this module.

[@SwampSurfer69]

My thought as well...🫡

[@pixelfrenzy]

Great sound for something so simple!

[@jenniferw8963]

Love it :) I'm definitely going to make one of these on my breadboard and try it out :)

[@wunderbar-q6y]

interesting. is the pcb with vcc and ground lane (3:17) premade or made by yourself??

[@HAGIWO]

Yes, this panel is my design.

@@HAGIWO thanks !

[@AnalogDude_]

looks similar to the TR-808, very cool.

[@the2d]

I need this in my life. I may try with both cd4006 noise and your noise circuit to see what I like, or both. Why not?

[@mcshafty1]

Sounds great!
