OTHER New Expansion: MPC P-Bass (For MPC3 & MPC Sample)

Post image
32 Upvotes

New Instrument Expansion Release! This one has been a long time in the making and a real labour of love for me, so I'm very proud to finally announce the release of MPC P-Bass.

This instrument expansion features a deeply multisampled Fender Precision Bass guitar recorded with multiple playing articulations with up to 7 velocity layers and 4 round robins to perfectly capture the nuance and tone of the original instrument.

All instruments take full advantage of the latest MPC3 features such as advanced keygroups and complex mod matrix programming to create an eclectic collection of presets and MIDI patterns covering a broad range of bass sounds & grooves.

Each instrument comes with an extensive array of editable options, all easily controlled with dedicated Q-LINK macros for a near plugin-like experience. Configure natural sound FX such as string squeaks and fret release noises, adjust guitar tone & FX and even change the entire character of an existing guitar performance with the turn of a dial, from soft and gentle to hard and 'buzzy'.

MPC P-Bass is built for any standalone MPC running MPC3.9+, MPC Software 3.9+ and Force 3.9+. It also features a dedicated MPC Sample edition with multisampled 'Starter' projects and a 16 LEVEL one shot library. Please note that MPC2 is not supported in this release.

Multi-Buy Offer: Buy MPC P-Bass with any other product or bundle & get 15% off your entire order.

DISCUSSION A warning about custom MPC operating systems, AI-generated code, and potential hardware risks (2000 / 2000xl)

194 Upvotes

I'm a software engineer with over 28 years of experience, and recently I've been reverse-engineering the new free Akai MPC2000 and the new MPC2000XL operating system using Ghidra, as well as emulating the sampler to better understand how its firmware interacts with the hardware.

During my analysis, I found some potentially concerning behavior, including CPU loops that continuously poll hardware without an apparent timeout. Under certain conditions, such as a peripheral failing to respond, these routines could leave the CPU repeatedly executing instructions instead of progressing normally.

This can potentially increase processor activity, power consumption, and heat generation. The risks also include system freezes, memory corruption, and unpredictable behavior.

Now, here's my main concern.

I'm absolutely not against using AI to develop custom operating systems for MPCs or other vintage hardware. AI can be an incredibly useful development tool.

However, I'm seeing more people attempting low-level firmware development without necessarily having the experience required to understand what the generated code is actually doing.

And that's where things can become dangerous.

We're not talking about building a website or writing a simple application. We're dealing with assembly, machine instructions, memory addresses, interrupts, and direct communication with physical hardware.

AI models also have far less publicly available training material for niche, decades-old embedded architectures compared to modern high-level programming languages. This makes blindly trusting generated assembly code particularly risky.

The problem isn't AI. The problem is using AI-generated code without having the technical knowledge to properly review, debug, and validate it.

A firmware modification that appears to work perfectly during normal operation could still contain subtle bugs that only appear under specific hardware conditions.

And remember, we're dealing with machines that are nearly 30 years old. Some components are already aging, and there's no reason to introduce unnecessary risks.

My advice is simple: be cautious about installing custom operating systems unless they've undergone serious technical review and extensive testing.

That means proper reverse engineering and code inspection using tools like Ghidra, testing in an emulator, checking memory access and hardware interactions, and eventually validating the firmware on real hardware under controlled conditions.

Just because an OS boots and its new features work doesn't mean it's safe or reliable.

I'm all for innovation, and keeping these legendary samplers alive.

But when software directly controls hardware, proper engineering and testing should never be optional.

I'd be interested to hear what other MPC developers and owners think about this.

QUESTION Mpc one+ exporting stems issues

• Upvotes

Has anyone had issues exporting sessions from their mpc one+ to the sd card and the folder is blank? This has been happening with my sessions transferred from the mpc sample only for some reason…. The session loads on my mpc one+ but it doesn’t export the stems and the folder is empty when I load the sdcard on my computer. Please help! Thank you.

Installed a new lcd screen today.

The old one was burnt out for the second time, already cleaned it at some point.

It came back with vertical stripes. So I ordered a new one from marunio UK.

Happy days!!

QUESTION Native Instruments Play Bundle - Cant install on MPC?

9 Upvotes

NI is offering bundles, 2 plugins and some expansions for $49. There was a bundle that had everything I've been eyeing from them, so I bought it. However, unlike the other Play instruments I bought, I cant find a serial or anything anywhere - not in my InMusic profile nor my Native Instruments account (same profile).

My MPC also isnt registering that I bought them, because if I go my activations page, I still just have a "GET TRIAL" button instead of activate. Its been a while since I bought the NI Play plugins.

I cant find a spot that has the serials for the plugins (Homage, Sway, etc) OR a place to download the expansions like I used to

Am I missing something or is something off here because its a bundle?

QUESTION [TECHNIQUE] - From song to sample

1 Upvotes

How do you identify good sections in a song, and do you look for loops or bits to cut out first?

Personally, I loop a single measure in Ableton over the drums, but I feel like it’s a waste of time.

Do you have any tips for finding interesting sections?

QUESTION MPC 3.9 Arranger

4 Upvotes

Before 3.9, I’m pretty sure you used to be able to clear out segments of a single track in the arranger. You would set the loop, go to edit, and one of the buttons would clear only the events in the selected track in the selected loop. Now, I can’t find a way to clear events in a single track. It just cuts all of the tracks from the selected loop. Any way to delete from a single track? This was how I arranged beats.

I know a potential workaround would be to build the beat in the clip matrix and then drop it into arrange but that’s not what I’m used to (might have to get used to it)

QUESTION mpc sample workflow with fl studio

2 Upvotes

i’ve been making music for nine years in fl studio and have been looking at getting the mpc sample since it was announced. i’m not very experienced in using pads besides very occasional finger drumming on my midi keyboard (arturia keylab mk3), but it’s always intrigued me (mostly for chopping samples).

i’d probably be using it mostly to load in a sample on my computer, chop it on the mpc, then send it back to fl studio. having a dedicated sampler sounds cool to me, but i feel like i might be just as well off with a midi controller with a bunch of pads on it if this is what i’ll mostly be using it for, but i’m not sure. the main thing is i would like the sampling experience to feel less like it’s all done in the computer and i can actually adjust things with pads and knobs to make it more fun. if a bunch of midi pads can do that and for cheaper, i feel like i might as well save my money.

any perspectives and opinions on this are appreciated

QUESTION MPC Live 3 + Torso S4 or MIDI controller?

2 Upvotes

Hello all, I’m currently using the Live 3 (and love it), and am looking to add another piece of gear for live performances. Particularly, to mangle/shape instruments launched via the clip matrix.

I primarily make electronic/pop stuff, but I also use plenty of acoustic sounds too. I’ve been mapping things to q-links and the step buttons when playing live, which has been great for some punch in effects through the flex beat player. This uses up a fair amount of q-links, as well as the touch strip.

Currently, im looking at either a Torso S4, or just a midi controller like the Launch Control XL to apply filters, delays, reverb, etc. I could use some advice from anyone that uses other gear with their MPC, particularly for live performance/DJ style fx too.

I like the idea of looping and live granular that the S-4 provides. Could make for some very interesting textures, and the loop function could be great to transition between songs.

The Launch Control seems significantly easier to implement, can still affect filters and whatnot, but does not solve my problem for transitioning between songs.

I appreciate any feedback on this! Thx 🫡
