TB-303 owner here. If my TB-303 sounded this bad I'd set fire to it ;-) Really this is just an implementation of a basic oscillator, filter and envelope. No harm in that all and it's more than I could manage - it's fun and nice, but it's nothing like a 303. "Building an acid synth" would be fairer. The accent and glide are core components of the sound, as is the really quite unique sequencer control - from the strang…

they should have referenced Rebirth - that one was spot on (i never owned a 303 though, just got access to one occasionally)

I remember playing with Rebirth in the late '90s and then actually finding a real, TB-303, albeit with a bunch of drawn on crap. But it was very functional. Keeping it in a box for my daughter. She will either think it's cool or sell it after I'm gone. If she sells it, hopefully she gets some decent coin. I'm kinda tempted to give it to my neighbor's son though. He knows about all this stuff and loves it. He'd apprec…

You could always invite him over to check it out, just to see how he reacts to it, and if he's interested more in the tech aspect or the music aspect. Due to the increased rarity of the device, you'd probably want to find out if he would actually use the device, or try taking it apart to see how it works. I'm not sure how old your daughter is, but you could try asking her if she would be upset if you allowed the neighbor to play with the device, just to avoid any ill feelings.

It sounds like you've got some great options either way. I wish I had a neighbor growing up that had cool music gear (although I did get to grow up with a dad that got me into computers before I could read, so that definitely built my love for technology). Sounds like you're the kind of dad more kids these days need in their lives.

I, too, have a TB-303.

It seems like there might be a disproportionate number of 303 owners here on HN.

me too, and many clones...

What do you think about mine implementation? https://drumpatterns.onether.com/drumkit/roland-tb-303/

I don't know what this website is made off but not being able to use pgup/pgdown to move around is super annoying.

What's your OS/browser? On Chrome/Linux it works fine. If you're focused on an editor it can capture the page keys so you have to click outside first.

I'm seeing the same issue as GP on Firefox/macOS

This I don't understand. DINsync is raw trigger outputs/inputs like you'd have in a modular synth, in contrast to MIDI that has to send serial messages over a 1k data bus. Perhaps this take has something to do with calling a five-pin DIN plug '5-pole'? Something's wrong and backwards here. Again, I guess this is where we are now? I remember reality, but here we are.

DIN sync is not trigger based, it's a full clock protocol invented by Roland that has various different states. The fact is that not all DIN sync capable machines implement it the correct way, leading to slight differences in synchronisation, even between devices made by Roland.

Interesting, I'd be curious to read a technical analysis of the differences. DIN provides by far the tightest sync we've ever seen in hardware, so I question the idea that lag and latency are a defining feature of the protocol.
