[MPCX] USB MIDI Implementation (In *AND* Out Ports via USB, PLEASE!)

My newly arrived USB3 8x8 MIDI interface (by MidiPlus) works with the MPCX.

Or in different words, the hardware works with the MPCX, easy, but the software works about a quarter of the way.

I know that Akai's recommendation is to use only controllers, but that is seriously neglecting a surreal opportunity (and it's a bit messed up, IMO). Controllers often also have MIDI Out Ports too, why could we not use them too, just like the in ports.

Anyways, I am getting ahead of myself here.

The 8 In Ports works great, OTHER than the bleeding obvious, which is that I cannot use them independently for different tracks, i.e. they ALL work ONLY for the currently selected Track. Need to be able to assign different MIDI Ports and Channels to Tracks.

The 8 Out Ports does not show at all, like the MPCX does not even evaluate them. PLEASE for the love of MIDI, let's use USB MIDI Out Ports.

This is a USB3 interface enabling my MPCX to have 10 In Ports and 12 (yes, twelve) Out Ports in total, that is insanely beautiful for a standalone graphical touch UI sequencing device, likely a first even. The only thing missing is a bit of software sugar. Please, let's have a full, fantastically feature rich MIDI implementation for the internal and external possibilities.

As so many before me have pointed out, previous MPC machines have had great MIDI implementations, and it would be a crime to let a machine as advanced as this, NOT benefit from all it can muster, which is way more than previous hardware.

I do understand that you guys have a lot on your plate, but you put the MIDI Ports on this thing, and you made it possible to add external MIDI Ports. NOT a complaint, but a straight up BRAVO! But please sugar coat it. Frosting works too. Just sweeten those tart MIDI bits, PLEASE!!!

  • Hey Robert,

    Thanks for posting!

    I would love to see more MIDI functionality come to the MPC hardware so in an effort to get the right eyes on this request, be sure to submit this as a feature request with the MPC 2.0 Software's built-in feedback module. The feedback module is represented by a smiley icon at the lower right side of the software next to the browser icons. This information goes directly to the Akai team for consideration!

    If you need an alternative method of submitting feedback, you may use the following links:

    Thanks for your feedback!

  • Good morning my friend. I am struggling with the basics of how to plug my kiorg M3 into my MPCX utilizing the functionality of my korg M3 with regards to keyboard sounds can you help me understand what reasonable expectations I should have. I see videos where people are using their controller with the The MPC ex and able to record their keyboard parts as midi in addition to using the drum tracks from the in MPCX. Thank you.

  • Your KORG M3 has MIDI Ports Thru, Out and In. The MPCX also has MIDI Ports, although more of them.

    Basically, you would take two MIDI cables (typical 5-pin DIN) and start by connecting the first cable from the Out on the M3 to the In1 on the MPCX, then take the second cable and connect the Out1 on the MPCX to the In on the M3. You now have electrical connections between the two devices.

    The problem with this kind of a setup is that it is a straight loop, right? You may get feedback, not the audio kind, but the digital kind. This is why there should be an option somewhere in the M3 to turn 'Local Control' to off.

    MIDI Local Control disables the direct connection between the keyboard and the sound generator within the M3.

    Instead the message path now goes... M3 keyboard > MIDI Out > MPCX > MIDI Out1 > MIDI In > M3 sound engine. (I am using the port identities from earlier.)

    So this part of MIDI was fairly easy to understand. Well, that is what I imagine.

    Now, the M3 can play multiple sounds at the same time. In MIDI terms, this is often referred to as multi-timbral, or some form of multi mode. MIDI does not do audio, but rather plays keys, sort of like an old 'player piano' works.

    In other words, when you press a key on the M3, a MIDI message (a.k.a. Event) will be sent to the MPCX and re-transmitted from the MPCX back to the M3 (this is the loop which must be broken within the M3, or that event will be re-transmitted again from the M3 internally, creating an endless loop). When you let go of that key, another MIDI Event is sent from the M3 to the MPCX and again re-transmitted to the M3.

    Along this path of the message, any device (first the MPCX, secondly the M3) may be set to actually trigger a sound.

    A sequencer (like the MPCX or the one in the M3) records these MIDI Events so that they can be re-played later (i.e. like a player piano).
