If I have zero experience designing PCBs but wanted to do a similarly (non)-complex one, how much of a tall order would that be? In my completely made-up mental model, I'm guessing I just take the parts I've already breadboarded, look them up in some sidebar, and drag and drop them around, snapping to nice clean spacing, and then connect all the various pins together and have it automatically organize things? We're n…

I'm not a kid. I still want it !

Same. It's a solid four-note ARP that sticks to a fixed set of musical keys. You literally can't make bad sounding music with this.

A more grown-up version of this would be 16 notes, with variable length patterns (4-16?), and a "swing" function. A little bit of I/O mux under the hood and I bet this design could be expanded in that way. Or maybe you just daisy-chain multiple sequencers?

It's not kid friendly, but in case anybody's interested I just wrote up how I made a simple "hardware" synth by bodging together a Raspberry Pi Pico 2 and I2S audio module, total cost around £10 on Amazon UK.

The hardware's very cheap and easy. The "default" synthesis is pretty simple but also pretty hackable (in Rust) if you want to customize it.

Earlier quoted context omitted.

How are these, are they worth the money? I have seen these before, but thought they might be crappy "jokes". However, if they are decent, I would love to play around with them.

They -are- decent modular chunks. They have a bit of opinion pushing you in certain directions as far as sound goes. Each one does a pretty limited set of things and combining them can be annoying. But you get a lot for the money you spend on them.

combining them can be annoying

The strong design opinions about how the Pocket Operators interact with other musical gear are a big part of why I haven’t had high enthusiasm for using the small PO’s when I’ve had small PO’s.

For me, Volca’s are a similar ecosystem but to a lesser extent…maybe because the Monotrons sit lower in Korg’s product portfolio while the PO’s are rock bottom of TE’s product line.

The traditional approach is you give noisemaking toys to your niblings, not your own children.

This sounds like a lesson I’m going to be learning the hard way

Good parenting is doing things the hard way.

So why not go all in with a full set of acoustic drums?

This ends at Eurorack.

Looks so nice! The sam is a midi synth chip right? Super cool. How/where did you get the knobs?

Thanks! Yes it's a little digital synth that receives MIDI. I used Chroma Cap knobs: https://store.djtechtools.com/products/chroma-caps-knobs-and...

Aah kool, i had one in a arduino format board, was great to cycle through all the instruments randomly + some sequence/chords. Instant Aphex Twin

jmb99 already said the part about cost/price. I just made a PCB for someone’s Halloween costume and it was only the 4th PCB I ever made. (So far I’ve used PCBWay for all 4 but since I’m in the US I also ended up doing a rush order from US-based Osh Park because I was panicking about how long the shipping was taking. Tariff situation has made shipping from China to the US more complicated. I found out DKRed, which is…

+1 to /r/PrintedCircuitBoard. It's exactly the community GP is looking for.
