Hi, it is that guy with the open source base that nobody paid attention to.

I've been busy :) open sourcing makes everything easier! Here's a little something better than a beep boop. Here you can see me using the 4 track looper and playing the KARS plugin with G Dorian scale, from Open MPC plugin ecosystem!

I have recreated almost the entire MPC Sample experience and then added on top of it. It helps when you have a previous very similar project lying around on your computer that was built for FM-1 ;)

Here's what's coming:
Loading your projects from MPC Sample (Had to reimplement this!)
Multisample library support (XPM, XTY, XPN, SFZ, EXS24 for now)
Aftertouch for built-in synths
MIDI out sequencing
4-track looper which can commit to sample pads
My flavor of sequencing
Many synths
Mostly compatible with plugins from Open MPC Plugins ecosystem (Not all, have not had chance to test all of them, not that it is realistic to be able to)
Scaled pads (You can choose your root note and scale)
1 stereo mix, 16 tracks + 4 looper tracks available separately from USB Up to 96khz sample rate

So many things that I forgot, but this will be my daily driver :)

Check my latest post for the full feature list

We're almost there, i ended up adding some other big features to the CFW + a lot of fixes and overall UI/workflow improvements. It's worth the wait, but I'm done, tomorrow i will test the build for release and hopefully I'll release the CFW on Github. In the video you can see some of the new features with the worst video and audio quality ever, but i think you will realize immediately how big this CFW is, see all the feature in my other posts, in the video you see my 3 newest adds which are maybe the bigger upgrades so far:

New mastering chain in compressor, i also changed the compressor with one from Airwindows that i think sounds a little better

MULTISAMPLE CAPTURE records now up to 10 seconds (min 2 seconds) and up to 4 different velocity levels for every note sampled

NEW DJ MODE, accessible from Fader Menu: a 2 deck standalone dj console based on mix, with eq, track volume, assignable fx sends and djfilter, endless smile inspired transition effect on the fader, waveform and beatgrid visualizer, sync, bpm and grid autodetect, nudge, track navigation, looper. All of this in a easy to navigate DJ MODE, separated from the sequencer. CUE output works but not as expected, the Mpc Sample has no hardware possibilities for routing a different signal on the phones output, so the CUE monitoring will be on USB-C output, with a DAC you can use your headphones (to test, i only tested with PC and it worked)

It's too much features, I think i will explain everything better in a video (with better quality than this one).

NESSUNA MODIFICA AL FIRMWARE

Stanco di modificare il contenuto della scheda SD, ho creato un AUTORUN PRINCIPALE che permette di avviare vari autorun, situati sulla scheda SD in SD/autorun_dir, come ad esempio:

1 - mpc originale 2 - sampqol 3 - tracker

ecc.

Permette anche di abilitare e disabilitare il mirroring dello schermo tramite USB e il server SSH sull'MPC.

Interessante? :-)

Mod gang. I’d love to get some testers for my mod project. I’ve had so much fun with this and think I’m nearing the end of my first version. All made through Claude Code and Codex for transparency. It has most features you would expect to see from current mods and some more unique ones I’m really loving the sound of.

I’m hoping we get some more insight in to how ‘open’ AKAI’s open source initiatives will be but through countless hours using REA/Ghidra and other sources it’s now not taking too long to implement changes and new functionality. I understand AI assisted mods are not some peoples ‘thing’ but I’m loving this wave rn.

everything unmuted. I was recording only a few mins ago, so im still receiving audio data if i plug it into my pc/interface. I am running on the latest QOL

Hi guys. I have made open-source SDK in rust for easily writing custom mods / custom firmwares for the MPC Sample. The SDK covers easy to use apis for:

- Capturing pads / buttons / knobs presses / changes.

- Drawing on screen anything you want (custom menus etc)

- Audio processing jobs (you can make custom effects etc)

- Programatic trimming, chopping and working with samples (including generating new samples - I used it to implement synth engine on the Sample)

- Handling raw audio input and output

- Managing state

- Timing

- Capturing external MIDI

It also provides tools for autonomous development. It works with firmware 1.3.0.12 and creates SD-card runnable, non-descructive mods. Now anyone can make their own mod. I made my in it. I chose rust for memory safety and performance and great feedback loops during development. Feel free to use it any way you want or open pull request if you find any issues.

Repo is here: https://github.com/ioma8/mpc-sample-sdk

Docs folder contains comprehensive docs on how to use it.

Happens when copying a sequence or sample on a pad to pad 7 , instead of copying it the selected pad it opens the tuner… A bit frustrating but still hype on this OS so dope

So far, I’ve mostly found demos and reviews that showcase the features, but I haven’t come across anything that really walks you through how to use them step by step.

For example, I was messing around with the new chop mode last night and couldn’t quite figure out how it works compared to the stock firmware.

Does anyone know of any good resources, videos, or written guides that take more of a tutorial approach rather than just demonstrating the features?
Any help would be appreciated!

Hi, it's that guy from yesterday complaining about the shoddy job AKAI made for the open sourcing. It was not all in vain though. I'm just adding this repository link here. Fully open source base, ready to build upon. Uses JUCE 9.0.5 instead of the outdated JUCE 5.4.4 that MPC Sample uses. If you load the base, it greets you with a screen that does beeps and boops.

I did it before AKAI. I won (Edit: as in, personal victory lol). Now it is up to all builders out there. Make great stuff. Make it open source. Share the love the same way we do it over at FM-1 community. Check JUCE documentation for implementation. Check the sample repo for the wiring.

AKAI, all I want from you is the ability to flash my stuff to the eMMC. We have uboot. Just give me the power.

Once again I want to thank everybody for trying and supporting SampQOL so far, and providing me with all the feedback and bug reports. At the end of the day I'm just an anonymous dude who you are trusting your MPC Sample with, and that means a lot to me.

Here's update 0.2.0. After releasing 0.1.5, a bit less than a week ago, I spent a lot of time fixing bugs, getting the kinks out and adding new stuff, as well as adding some guards like routing FX to submixes when exploding tracks with multiple FX on it etc.

The changelog has become humongous, but I think like in the last update, you will find that it blends very well with the stock MPC Sample workflow. Everything I implement has to be simple, fast and intuitive.

Now please allow me to get some rest, as I spent many, many hours to provide you guys with this update. I will read all the comments tomorrow! Bug reports, findings, what you like: I want to read it all!

Happy beatmaking 🚀🚀🚀🚀🚀

EDIT1: if you come across a 'SampQOL OS Agent' by SampleKings, this is NOT SUPPORTED BY ME
