MPC 3.4.2 Bug Reports

On MPC X SE

When in song mode, playing, then changing to Mixer to adjust levels: Cannot go back to Song mode , and Song mode only playing the same sequence.

I'm new to MPC, but it doesn't seem to be right.

When you exit the Song Mode screen, Song Mode is deactivated. After converting the song to a single sequence using "Conv > Seq", make any necessary adjustments.

Thanks! Coming from a DAW some things are obviously different

Does anyone understand the rationale behind that behaviour ? What downsides would occur if song mode was a global state, kept while the song is playing, regardless of navigation ?

The browser, when pushing "left" to go up a level, very often goes to the top of the directory instead of staying at the entry i'm coming from below. This makes browsing larger directories quite annoying.
MPX X SE 3.4.3

When editing a keygroup track in grid mode, notes below C1 are shown at the top of the grid.
When editing them in list mode, the note editing field wraps at 127, and tops at 35.

I didn't take a video so I don't know how helpful this will be but while using the MPC, the Play and Play Start button didn't work (pressing it didn't do anything). I didn't change any settings up to that point. Record, overdub and stop was still working. I could play the track from the main page and pressing the play button on the touch screen.

Restarting the MPC didn't work. Eventually fixed after I loaded a new project. Recorded something, Tested the play button. It worked. Then I closed the project and reopened the old project and it was working again.

MPC Key 37 stuck at the hourglass screen after switching back to standalone from controller mode.

When I switch back to Standalone mode from Controller, it shows the hourglass loading screen and is stuck there. I've dismounted the drive properly before switching back. But it still hangs. I have to hold the power button until it shuts off then turn it back on but then I get a message that I powered off incorrectly. I'm afraid it will affect the hardware in the long run. Anyone experiences this and has any fixes?

Bug MIDI mapping MPC One – firmware 3.4.x
Since the update to 3.4.x, I have a critical bug with the MIDI reception on my MPC One.
When I connect a master keyboard to MIDI DIN or USB-A (tested with two keyboards: Arturia Keystep 37 + other model), the incoming notes are disordered or transposed. Some notes of one octave correspond to another, some are inaudible.
I do not have this problem via USB-B (mode controller MPC Software), nor in firmware 2.x.
I tested several cables, reset the parameters, nothing does.
Have other users noticed this? Known bug?
I reported it via the Akai support but I didn’t get back.

Hi folks,

I promised to give an update on my experience with AKAI/inMusic regarding the handling of my bug-report of the "hissing" noise bug in the MPC-OS 3.x.x sound engine described here: viewtopic.php?f=48&t=218984&start=45#p1891964. So .. here we go:

April 9th 2025 - I reported the bug by opening a ticket on the AKAI-pro support website https://support.akaipro.com/de/support/home.

April 11th 2025 - I received a reply e-mail from AKAI support with an apology that it took them so long (2 days) to send me a conformation that my ticket was received and ensuring me that my enquiry is important to them.

April 14th 2025 - I received another more very nice and more personal e-mail by an AKAI/inMusic support staff named John, telling me that he had passed my ticket to the relevant department and thanking me for my time and efforts compiling the related information. I was also ensured that any follow-up questions will be answered.

April 15th 2025 - I did sent an answer to John telling him that I would be pleased if he can inform me about the status of the ticket from time to time and that I had promised to give regular updates to you guys.
Some minutes later I received another very nice reply from John that I quoted here:

<quote>I have just passed my report to the Dev team who are currently evaluating my findings. I am awaiting them to get back to me regarding it for a resolution."

In the meantime, please feel free to let me know if you have any other questions or concerns and I will be happy to help.

I will keep your ticket open on my inbox for now as requested, and let you know as soon as I hear something.

I hope you have a good day! </quote>

I can say that I'm very pleased on how my ticket is handled by the AKAI/inMusic support so far and I hope this will continue and the bug will be fixed soon. I'll keep you all updated when receiving new information.

All best

@Admins: Feel free to move this post to a new thread if you don't want the updates to be posted in this thread?! Thanks in advance!

Didn't see this one...

Key61 and Live 2

On a "crowded" track (lots of events), the select note tool in grid mode hangs - sometimes a few seconds before actually making the selection. Can be quite annoying!

MPC MIDI Mapping broken. Cannot figure out what is going on.

To use a controller for MIDI Learn, try activating the Control button in the MIDI settings screen.

Boy this is embarrassing... that was it. I must have done it instinctively the first time and forgotten after switching controllers.... thank you. Feel free to delete if it muddies the waters.
