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 " stop Send's the stop 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 " eject Send's the eject sysex to MPC"
echo " chase Send's the chase sysex to MPC"
