Yes, I'm wondering if routing has been sorted in version 3. Both audio and midi routing between plugins (sidechain etc, ...) on different channels/pads and busses is desperately needed to keep up with modern DAW requirements. Then I could actually use things like Trackspacer and those EQ plugins that work together when put across multiple tracks.


This here + PDC and I could abandon all other DAWs forever lmao

I noticed, try the arranger on MPC :), the software is here, but many things aren't yet as on MPC

I don't think so. I couldn't get Scaler 2 to work. I had to load up unify and do it that way. And then you can't drag your recorded midi from scaler 2 to the mpc now.

These bugs were when I used the MPC One + 3.5 in standalone mode with MPC 3.5 software.

1. Empty VST3 Presets.
Empty VST3 Presets show empty on PC. You can save them on MPC hardware and software, and load, but once done, it shows empty.

2. Audiomixdown silent audio file.
After converting to sequence, and from the arranger screen to the menu, to save to Audiomixdown at the default, just add 3 seconds. It writes an empty audio file. saved in a new folder under
C:..... ./documents/mpc3/stefsamples/.. tried 2 times. Then I tried exporting the song instead, and that worked successfully. It's still different because the song mode is different from the compiled (conv-seq) sequence of the song if edited.

3. Each time I change the TC, the pads return to bank A.
While recording, I change the TC sometimes, and each time after that, the pads are set to bank A.

4. still blue bootscreen wifi... after new help screen with QR code. need to go through 3 splash screens
to boot.

5. Chords Pro/ W.A. Production, it's a VST3 that outputs MIDI. i wonder how it would work on MPC 3.5?
Kontakt 8 can output MIDI too but I haven't got it to work in MPC 3.5

thank you :)

ps: I successfully loaded a project made on MPC One+. in MPC 3.5 software with MPC in standalone mode :)

I would like to see chord inversions, low mid high root etc...



Well damn, let me add mine:

• Multitimbral doesn't seem to be working. I.e. 1 instance of kontakt with 16 channels routed to 16 different midi tracks in the MPC
• Not being able to adjust the time signature from anything other than 4/4
• drag and drop Doesn't work at all. At the very least go back to how it worked in 2.15 but this was 1 of the things I was hoping would be improved in 3.5. Where we can just drag midi on track 2 and it's there instantly like how FL or Ableton works.
• When you switch from 1 track type (plugin, drum, audio) to another, it removes the name of the track and you have to Rename it again.
• Imported templates from 2.15 doesn’t completely work with Multitimbral setup when using vsti. Can only hear midi channel 1 and the rest of the tracks are still set to the default source even after full plugin scan.
• Go back to track mute mode only showing 2 colors like it was in 2.15. It’s confusing to know what’s on and what’s muted now with the pads being different colors. Yellow on & red off was cool or, allow for the user to customize the colors.
• Can't load or save effects racks chains
• Track and sequence Events double and half speed options are gone
• Latency on Izotope Ozone 11 even when the effect chain is turned off and the overall insert effects are turned off.
• Waves plugin GUI sometimes shows up as black screen
• Unable to customize the top toolbar with the different views the way you could in MPC 2.15
• Cableguys Halftime, Flexbeat, Shaperbox 3 (Time Tool) seem to cause distortion, popping and clicking. It’s almost as if these are using the max amount of memory and causing the pc to slow down. These are on my template in MPC 2.15 and I’ve never had this issue. It seems to be only time-based FX that I’ve experienced this on as the panning and filtering tools in Shaperbox 3 sound fine. I tried this on submix 1 and Output 1/2, as well as on an individual Plugin track on a Lead using Serum and I get the same result. My buffer setting was set to 1024 at 44100 Sample Rate.
• Insert effects power button is on as well as the selected effect, but the effect still shows grayed out. If you click it, it will light up for a second but then just opens the effect interface. Although, it is grayed out it appears to be active while the button is active. It is a little confusing

I did report these to Akai. let us know if any of you guys figure some of this stuff out

OK, here's mine:
First, it wouldn't load my old template, giving two errors, file not found and incompatible file type. So, I spent all morning rebuilding my template from scratch. I tested it after every track/program by saving and then reloading. It worked fine until about the 6th track/program.

It is saving all the files to the disk. After the 6th it simply won't load them back up. They show in the browser with a red icon on each "missing" file. All the files are known good. I can't imagine why it's showing "incompatible file type" on files that are 16/44.1, that loaded and saved fine and work perfectly on 2.x.

Again, I'm rebuilding the track/programs, not importing them. They're working fine until step 3. So obviously I can't load any old project because they're based on the old template. Kinda silly to even have slots for samples if you can't load them up. I'm not filling it up even halfway.

Yes I understand it's a beta so we'll see. :popcorn:

Is akai clueless?

There’s an even better serum bug where it plays the lfo back at half the speed when you trigger events from the grid ……


For those of you that perhaps want to use vst3 with mpc2 (or even with mpc3 and avoid the latency problems) you can use this, works a treat https://www.bluecataudio.com/Products/P ... PatchWork/

Hello,

I cannot find Stem Separation in the 3.5 Desktop Software.
Inside of my Activations (right click on the top right corner -> My Activations)
I clicked on Activate and downloaded it.

Even after restarting the software I cannot find this function :?

Thanks for any help!

Once, I could drag the progression from Chords Pro into the MPC 3.5 software. But only once. Now when my mpc one + is in controller mode and MPC 3.5 software, when I load a midi file then the software crashes to desktop. it doesn't crashes when mpc 3.5 software on PC is alone without mpc one plus

I'm just getting my feet wet with 3.5 after I downgraded from the hardware "beta" a while back.

This is one quirky piece of software. It doesn't have anything that I would call useful, but it is a beta. VST3 support is spotty, MIDI mapping is still broken (more on that in a few), and crashes are everywhere. But this should have been expected.

I'm convinced the only reason for this release is to say they released something in May. I have a sliver of hope that it might get better, but this is going to take some time. Wake me when 3.10 drops, but for now, it's back to 2.15.1 so I can actually get some work done.

Something strange I discovered while messing around with my TR-08... MIDI Mapping is borked in 3.x.x, this we all know but if you go to the sampler screen, it magically WORKS. Of course, this is 100% useless because if you move to any other screen, it goes back to shit.
I suspect that there is some old working code in the mix from 2.x.x as the foundation for 3.x.x and it's fighting to stay alive. I just want my programs back.

I was under the impression that 3.x was a full code rewrite, but this is not the case.

i drag midi files into the track, on mpc software 3.5 it works once. after that that feature ain't possible. even loading a midi file is not possible after that.

Im a bit annoyed with the mpc 37 as it looked awesome for what I needed, control multiple hardware synths, has keyboard and pads......videos on it explaining how to set it up and then Akai saying the first steps should be to upgrade the software and firmware and now I cant get rid of the 3 bloody splash screens on boot up and that includes the screen where you check a box to get rid of it and it still comes back up after a reboot. Ableton link doesnt want to play ball either after watching multiple videos on how to set it up....... :smh: clicking the 3 dots for reset mode menu does nothing as well. can I backdate the OS and firmware without causing any issues? ?
By Techno Assassin Mon Dec 22, 2025 8:23 pm
Update.......SO after some advice, and ableton link just randomly starting to work, the timing was dreadful, but after some help on another forum, using the MPC as the master and Ableton as the slave........on average 0.018ms latency recording audio into ableton which is awesome and pretty much imperceptible.....the only thing that comes close is elektrons overbridge so I'm well happy with that. I still cannot get rid of the 3 splash screens though which is an annoyance, but hopefully resolved in a future software update. Just to add that Ive done all the steps to try and remove the splash screens from having the startup loading an empty project to creating a default startup and no luck
