I'm trying to send a sysex patch dump to the MPC ONE but nothing is received.
Synth is connected with USB midi, sending a single patch.
I can record midi notes and CC messages in the MPC, they also play back as expected.

The midi monitor on the MPC One shows no incoming data when i perform the patch dump (176 bytes).
When i send the patch from the same synth to a sysex librarian on my computer, data is received.

Is it not possible to send and receive sysex patch dumps or is it a setting in the MPC that i overlooked?

That's not true, the new line of MPC is riddled with SYSEX. Also the top tier keyboards such as the MPK-249 and 261 send sysex to the mpc for transport controls like play start, play, stop, overdub and record and i assume for the pad-lights as well.

Maybe a malformed message, or perhaps you need to find out what akai's SYSEX messaging structure looks like to interpret how to send the right message.

if you have linux and a usb to 5 pin midi cable you can try it for yourself with this script to see that it does indeed work.

Code: Select all#!/bin/sh

if [ "$1" = "" ]; then
   echo "Usage: $0 [option]"
   echo ""
   echo "   stop                   Send's the stop sysex to MPC"
   echo "   play                   Send's the play sysex to MPC"
   echo "   differed-play          Send's the differed play sysex to MPC"
   echo "   forward                Send's the forward sysex to MPC"
   echo "   rewind                 Send's the rewind sysex to MPC"
   echo "   record-strobe          Send's the record strobe sysex to MPC"
   echo "   record-exit            Send's the record exit sysex to MPC"
   echo "   record-pause           Send's the record pause sysex to MPC"
   echo "   pause                  Send's the pause sysex to MPC"

   echo "   mmc-reset              Send's the mmc reset sysex to MPC"
   echo ""
   exit;

It's irrelevant to the question. The MPC's sequencer cannot record SYSEX dumps or transmit SYSEX dumps. That's what my message implied.

There are smart device apps that do sysex dumps. That could be a quick and easy mobile solution, provided you have the midi>usb phone cable.

TBH the majority of manufacturers these days neglect midi and sysex.

Why can't I launch clips or mute tracks over midi?

This is the reason why i kept hold of my 4K,for the purpose that it allows you to write and record Sysex dumps and sends sysex messages to external midi gear

The lack of ability to create your own Sysex strings or dump patch Sysex messages into the newer MPCs is a little odd IMO,I don't understand why Akai decided to omit this from the OS of the newer MPCs,the 4K handles this perfectly and most older hardware sequencers I've used allow this in some form.

Ok its probably not the most important feature of most MPC users, with the vast majority not understanding what Hexadecimal language is or does, but some of us Veteran midi guys with large Hardware setups like to dump patches at the start of a track in order that the External Midi gear is setup with the correct sounds/Templates,/Modes,
Sysex strings go beyond the scope of a basic program/Bank change message,especially for recalling different projects/sounds,if like myself you've change setups over the years having the ability to load all the correct sounds and settings dependant on the gear you used at the time and being able to go back to them even years after with all the correct settings is a lifesaver. i can load in projects done on the 4k 15 Years ago and know that it will dump all the correct patches on the external gear used at that time.

Having the ability to write and send Sysex strings yourself from the sequencer is also useful for being able to switch modes that normally require a button press on some external hardware devices too, very handy if your not within easy reach of the device itself or on stage

This is the very question I came by to ask. My One+ is the "brain" of my setup, and it would be awesome to be able to at least back up my patches into an MPC sequence.

Right now my backup solution involves Sysex Base for iPhone, a Bluetooth MIDI interface (CPE WIDI Jack), and saving to iCloud. Now if my house burns down, at least I can restore my next Prophet 5.

But this seems to be a weird oversight for the MPC. Even an MMT-8 can absorb sysex dumps.

I don't know about launching clips but you can mute tracks with the MPK 249. Just midi learn the switches. I do it all the time. Usually the first thing I do once I get my tracks laid out is midi learn the fader's knobs and switches which help me mix and the mutes help me perform subtractive arrangement on the fly.
