MPC 3.4.3 Release Notes
MPC 3 Firmware Update

Compatibility

This release is for MPC Key 37, MPC One+, MPC X Special Edition, MPC Key 61, MPC One, MPC Live II, MPC X and MPC Live hardware.

Desktop Software

In controller mode MPC remains compatible with the MPC 2.15 desktop software. However, please note that projects created in Standalone Mode on version 3.4 are not backward-compatible with the MPC 2.15 desktop software.

Downloading the Firmware Update

To download the 3.4 Firmware Update, use the online updater or navigate to MPC Software & Firmware Downloads and select the appropriate download.

For instructions on installing these updates, please visit our support page here.

Ongoing Improvements

We deeply appreciate the feedback from our MPC 3 beta users. Two key areas—Time Signature Support and the MIDI Note Off issue—have been at the forefront of your input. Please rest assured that we are actively working to address these concerns in a future update.

Bug Fixes

Using Convert to Sequence in Song Mode no longer causes a crash
Using Audio Mixdown on separate tracks with returns now only contains audio for the specific track. Other tracks cannot be heard in the resulting audio file
Improvements made for handling large sample loading
Splice is now present in Browser shortcuts
Wi-Fi Firmware upgrade to improve connectivity issues
For MIDI tracks, in Track Edit the MIDI CC Filter parameter filters MIDI CC messages correctly
Keygroup parameters load with the correct defaults when creating a new Keygroup track or when updating the current track type to Keygroup
When editing insert effects in Sampler mode the Q-links now assign correctly when in Screen mode
Resolved an issue in Drumsynth Multi where adjusting certain parameters of one drumsynth would affect parameters of another
For Drum and Keygroup tracks, Layer Play “Random” is no longer biased towards Layer 1
Using “Convert to Keygroup” in Track Edit for a pad on a drum track now creates a legacy keygroup which retains the parameter settings from the Drum track

Known Issues

Larger projects from 3.4.1 can fail to load with memory error
Factory Drum content does not display in Sounds mode for MPC One, MPC One+ and MPC Keys 37
After loading a project from an external drive, if the drive has been force ejected and reconnected, saving the project can result in missing samples when the project is loaded
Single Solo behaviour sometimes cancels when switching between multiple tracks
If event automation exists, inserting bars before bar 1 causes tracks to be event-muted in that region
Event Mute cannot be assigned in Q-Link Edit / MIDI Learn
Toggling effects on/off on 2 or more simultaneously causes UI to become out of sync
Activations list not accurate on first startup after updating
Metronome does't sound when set to Mono Output
Multiple uses of Double Length with Events on Arrangement causes UI to freeze
Load to Pool not working for Splice files on external drives
Program Changes with LSB & MSB cause note conflicts
Track Length setting is fixed in copied sequences
Using number pad to set Bank MSB and Bank LSB values for a MIDI track results in wrong value being set

[v3.4.3] [MPC Key 37] Still having Favorite sounds issues. When I tap on a Favorite, most of the time it selects the 1st patch for that plug-in. If I tap it again, it selects the correct patch. I have tried "Overwriting" the favorited patch, this does not help. If you stay within the same plug-in, all is fine when you change favorites. As soon as you select a favorite that belongs to a different plug-in, it selects the very first patch every time.

Example; I have patch "Fabric XL / Belly Stack" saved on Page 1 / Slot 4 of the Favorite patches. Upon clean boot, I go to Favorites. tap Slot 4 / Page 1 labelled "Belly Stack". And it loads "Fabric XL / Awakening". If I tap Slot 4 / Page 1 again, it actually loads "Belly Stack".

[Feature Request] Some Plug-Ins and Presets take much longer to load. The new NI plug-ins have a way of showing you that it's loading so you know when the patch is ready for playing. I wish all the MPC plug-ins did this. Like a progress/busy bar.

There are tons of bugs they are not even aware of.
Like the qlink settings in project mode made on MPC2 standalone, they are not loaded on MPC3, they are forgotten, and there is no mention about that anywhere.
Same for track mutes, they get lost when loaded on MPC3.
That is very disturbing and creepy.
I have the feeling there will never be a full compatibility between MPC2 and MPC3.
It seems they don't really give a hack about it.

OMG
So still no working q-links in screen control mode for Grid View editing.
Also seems there’s a new BIG problem with importing midi files - I tried three times to import a chord progression made in Logic (tested by re-importing to a new Logic project) - third attempt my MPC recognised the midi info and it shows in the arrange window on a plugin track - but it doesn’t play any sound.

Clicks and pops present with just a drum break and Stage Piano running.

Several presets double trigger during sequence playback (not all)
Several presets get “note on stuck” when double tapping stop (midi panic).

Has anyone experienced these bugs that they’ve fixed or are they just making them up. It’s actually quite pathetic
