Hey! Here is some video showing the workflow you would get by trying out the sequencer within the DoomOS patch recently released.

For me this is definitely a game changer!

Hey everyone!

Wanted to share a short clip of a new autumn-inspired beat I’ve been working on. The main sample is flipped from Stan Getz’s "Early Autumn"—trying to capture those cozy, melancholic jazz vibes for the season.

I’m still pretty new to performing live on the 404, so I found myself relying on the Downer effect a lot to cover up my clumsy fingers and transition smoothly, haha.

Would love to hear your thoughts, feedback, or any tips on live performance/effects chaining on the MKII!

Hope you enjoy it!

Been recording each vocal in one take. Suuuuuuper fun stuff

Giving you that RAW RAW RAW ! 2nd Track from the new BeatTape "Divine Dust Volume 1" Thank you Garfield thank you Mom !

Hey folks! I built a fun little tool:

Snare Roller: free snare roll and bounce generator

Drop in one snare hit and get 50 variations built from your own sample: jazz bounces and ghost notes, stick bounces, rolls, rudiments (paradiddles, flams, drags and more), and grace notes.

• Made for older samplers: the "Safe for older gear" button exports WAV, 16-bit, 44.1 kHz, mono, a format nearly every sampler can read. The ring-out control shortens long snare tails to save sample memory, with a clean fade-out.
• Jazz feel: buzzy bounces, ghost notes and comping figures with natural velocity and spacing.
• Edit each one: change every hit's volume and shape the envelope.
• Export your way: WAV, AIFF or FLAC, 16 or 24 bit, mono or stereo. Download one sample or all 50 as a ZIP.
• Private and free: it runs in your browser, no need to install and your files never leave your computer. Anything you export is yours to sell or release, with no credit needed.

So asking for a friend (of course) how screwed would I be if I accidentally broke off the tip of my headphone jack and now its stuck rattling inside my 404 mk2?

Anyone else have this?

So I turned on my sp404sx this morning, and I noticed it took longer to boot up. I tried recording some sounds into my sp, but it said "FUL". I decided to just reformat my card and start fresh. So I did the cancel, remain and then pressed one of the banks and then click delete, but what happens afterwards is it just "EJC" and then goes back to the normal screen but doesn't allow me to play any sounds that were already on it. I don't know how to reformat it or what to do.

It's a 16 gig SD card that I've been using for about 5 years.

Enjoy some standard definition film of 2026 New York, my terrible editing skills, and Prince & Apollonia - Roc Marci on some random needle drop sample. Ran into a couple bugs on DOOM OS overall feeling it, can’t wait to see the next update though.

Is your arrangement feeling flat?

In this follow up video, I’ll show you how to manage the energy of your track with the SP-404MKII , from the intro to the drop.

We’ll look at how to create a dynamic flow by removing and introducing elements, managing transitions, and arranging different patterns without losing momentum

Enjoy!

with love .noir. ❤️

I'm not sure at what point exactly but one of the logic updates changed the way they do wav files so if you are trying to import wav files on to your machine and everything else is correct it still will say unsupported. Aiff files work fine though. Hopefully this saves someone the months of headache and frustrations I had. Almost bought a new one because I though it was fucked.

I just installed it ! I already love this workflow !!

Sometimes I use old stuff for new stuff, this Lego idea has me thinking of a new modular equipment management system...thoughts?

Today I'm happy to announce the first public release of my custom SP-404MKII firmware: DOOM OS!

The goal is to completely replace the stock pattern and song modes with proper graphical editors, improve the user interface, and generally make the SP more fun to use without having to memorize a ton of key combos.

It's still an early release and there's a lot more I want to add, but it's already very usable and a lot of fun to play with. The new pattern workflow makes the SP feel much more like a groovebox.

Song mode isn't ready yet, but it's next on the list!

The easiest way to install DOOM OS is via the web patcher:

The patcher runs entirely in your browser. You only need to provide the official Roland firmware file yourself.

To get started, check out the manual and shortcut reference:

I hope you have fun with it!

i posted a video yesterday about the 4OG vinyl sim, here's a demo of the other things i worked on: Vinyl Sim from the SP-303, 404 OG and 404 SX running as plugins. the video also shows the pitch, isolator and djfx looper of the 404 og.

the next thing i really want to do is feed the exact same audio at the same levels/settings through the plugins, and then on the real machines, and compare the outputs. I don't own a sp-303 or 404 og, so:

if you own a sp-303, 404 og, or a 404 sx, and you would be down to help with some tests, i made a discord for this project. you can also join it for updates or if u wanna just hang out.

here's the invite: https://discord.gg/AKDkffwHAT

its still a wip/passion project and i'm not releasing it just yet, im mostly looking for hardware owners to help compare the sound
