MPC Live: software AU plugin in Logic Pro x - midi output problem

Hello,

I've tried to mail this directly to the support team, but the support form doesn't seem to work, I can't get my message sent... Hopefully there will be answers to my frustrating problem here:

The midi outputs of the AU plugin version of the MPC software don't seem to work in Logic Pro X. 

I can choose them in 'preferences' (port A - D), but they don't get remembered, even if they still show up when I create a midi program with one of these ports.

I create a midi program with one of these ports (that show up as available ports), but the midi simply doesn't get through. There's no signal to my external hardware and I don't see any signal in my midi monitor software at all.

When I want to check the 'preferences' again, the ports show up as 'empty' again, so the previously assigned MIDI ports don't seem to be remembered / saved...

Also, the 'DAW' midi doesn't seem to do anything, it doesn't send MIDI at all to my DAW. No signal in MIDI monitor again...

Everything works fine though in the 'standalone' version of the MPC software (MPC Live still as a controller), so I really can't get what's wrong.

I've been busy for hours trying to figuring this out, spending more time on technical issues than on creating stuff...

Specs:

- MPC Live, latest software and firmware (2.5)
- Logic pro x latest version
- Mac MINI late 2012 - Mojave OS, 16gb Ram, 2.6Ghz, 1Tb SSD disk.
- MIDI goes via iConnectivity MIO10 router / hub, latest software / firmware, directly connected to my Mac mini.

Please help me with this issue!

Thanks,

Luk

  • Hey loekazz,

    Thanks for posting!

    Sorry to hear that you are having trouble! This is a known issue with the MPC plugin. Even though you are able to select MIDI Out ports in MIDI Preferences, they will continually revert to none. This happens because there is essentially no virtual MIDI bus between Logic and the MPC Plugin.

    For the meantime, I suggest triggering MIDI events in Logic with the Live in Standalone mode. Another option that may interest you, is using a Virtual MIDI Driver, like Loopbe1 or loopMIDI for PC or the IAC bus for Macs. These programs will bus MIDI data from one DAW to another and can be synced via MC.

    An application like this could be implemented to form a MIDI bus between Logic and MPC (Standalone) with the Live in Controller mode for simultaneous control of both DAWs. While this is an appealing solution, its efficiency will very much depend on the processing power of your CPU.

    Hope this helps! Let me know if you have any questions.

  • Thanks for the quick reply and the suggestions for a workaround solution.

    As I was not trying to trigger events / VST's from Logic but rather trying to send MIDI from my MPC to some external HW synths, as part from a project in Logic, I needed to have the MIDI output ports in MPC AU plugin working.

    Now I understand why it's not working in Logic, though it actually should. I think in Ableton (VST) it worked, but not sure. The fact that it's not working in Logic should at least be mentioned somewhere in the documentation.

    Here's the 'complete' guide of AKAI about setting up the LIVE / X in Logic Pro x:

    https://www.akaipro.com/kb/akai-pro-m...

    there's almost no info about the MIDI routing, and no mention about the fact that MIDI routing simply doesn't work in Logic. 

    That very useful info could saved me already from some frustrating hours of scratching my head and finding out what's wrong....

    In the manual I only found this note about the routing:

    "Note: When using the MPC software as a plugin, the only option you can select for your Midi Out Port is your host software (DAW)."

    But even that is not working in Logic, and again no comment from AKAI about this. If that connection would work, at least we could route the MIDI going from MPC to DAW to an external MIDI output in the MIDI environment or via MIDI pipe or something similar.

    about the suggestions you've made:

    I had tried to use both software (Logic and MPC with the Live in controller mode) already, synced to Logic via my MIDI interface to the MPC's input, but that was not feeling very tight. 

    Via IAC it's working better now thanks, though that's still not an ideal solution because, like you said, it demands more from the processor compared to using the AU embedded version in Logic.

    Maybe working with an external clock could tighten things up more also...

    At least now I know what's the best workaround for me at this time, but still I've got some questions:

    - Ain't there really any solution to create those missing virtual MIDI busses between Logic and MPC within Logic (MIDI environment)?

    I've tried to figure that out also, but my understanding of the environment is still too basic, I'm afraid. If that's possible, AKAI could add this information in the article from above and in the software manual.

    - Will this issue of 'broken' MIDI ports in the AU ever be addressed by means of an update? Or does AKAI try to find a solution together with the development team of Logic?

    Thanks

  • mmm, timing of the MPC when slaved to Logic via IAC isn't that great either though, especially when looping a region in Logic the MPC starts drifting out of sync.

    So to be sure, the 'DAW' output is doing nothing also in Logic, even if the MIDI out signal in the MPC AU plugin is indicating it's sending MIDI out?

    I think the only option left is using an external clock...

  • to be sure, can someone from AKAI confirm the "DAW" routing doesn't work in Logic and that there's really no other way to route things in Logic (environment)?

    in that case using the software outside Logic and clock things externally will be the best solution.

  • Im having same troubles with midi out in Akai Mpc x controller mode. Just can set up «DAW» in the 4 midi out gaps in the plugin. And no answer. So my previous project cant go on cos my previous midi configuration (sending via Midi Out A to external synth) is gone in controller mode. Would like to know more about IAC bus in Mac..can it solve the problem then? Not much idea about that,just know to acces MIDI Setup in Mac and create bus in Iac Driver..but in logic dont know how to do. Would apprecciate any help. Also, loekazz, if you are ok will make a copy from your first post and attach it to mine to Akai query. Sorry about grammar mistakes. Regards

    • I forgot to mention that in the case of working with an external clock, you can use the Live in standalone mode also (so not using MPC Software), perfectly in sync with Logic!
    • Ey loekazz,thanks so much for the explination!
      Im afraid that my computer is very old (10 years) to work with IAC Driver.
      For the moment I just forgot about mpc software and have come back to midi cable sending clock from logic to akai as I was doing with my previous Mpc 2500. Actually I realized that do not need plugin (for the moment), just to bounce..so I can bounce without software the external synths first,and then load the Au Plugin and bounce the content from akai Will see how it works and check latency. I presume will need to invest in an external clock soon or later.
      Best regards and very thanks!

  • Will this MIDI routing within the plugin ever be addressed? Im curious as to why the MIDI option is even in the Preference panel if it cannot be changed. It makes it useless within Logic. What DAWs work with the MPC's plugin w/ regard to MIDI?
