super-sixteen VS O_C

I see designs with a single capacitor, some have diodes, some have inductors, some with a bit of everything like in the pic, and then there's Mutable Instrument schematics I don't follow at all yet. As I understand so far, the diodes protect against reverse polarity and I assume capacitors protect from current fluctuations?

I recently build a supersixteen sequencer with an arduino nano and it has zero noise, you could check the power section in the schematics, it uses some inductors and diodes in series, and some filtering caps

There's a guy Matthew Cieplak with a YT channel/company called Extralife who made a quite richly featured sequencer based on Arduino, and I think his code's up on Github - it's probably complicated by all the features he's built in but if you want to take a look, that's there...

The update just requires a standard USB AVR programmer with 6-pin header cable (here's one I like). The firmware update is available on the project github page, and installation details are included in the tutorial video and on the official update support thread on muffwiggler.

We can all dream for a port, but it seems like a lot of work to get around limitations in the speed of the SPI port on the 4.0. Most likely it would end up having to be a module with the heart of a Teensy 4.0 and some additional circuitry in order to get the needed performance, and it still requires a massive rewrite of several of the apps. Lots of people are clamoring for it, but nobody is stepping up to volunteer the hundreds of hours needed a to carry it out.

A serious project just right for CV modulation built around the Teensy microcontroller is the Ornament and Crime DIY module.

Ornament and Crime is open source and on github as is every mutable instrument module, including plaits. The Grone Drone seems to be a combination of digital and analog sections, a quick look at their website didn't tell me what's behind the oscillator section.
