A. Connect the MIDI Out of the keyboard to the MIDI In 1 of the MPC1000 and the MIDI Out A of the MPC1000 to the MIDI In of your keyboard.
Set your keyboard to LOCAL OFF.
On the MPC1000, Mode: MIDI/SYNC, MIDI tab, set "Active Track Receive Channel" to ALL and "Soft Thru" to AS TRACK. After that, your keyboard will play the same sounds as the pads, i.e. whatever is set on the selected Track. The MIDI field of the selected sequence Track, on the Main page, controls where you direct the MIDI output from that Track. You can use this in combination with the Program field, so one Track can control both the MPC1000 sampler and/or an external synth. To automatically select sounds on your synth, you can embed Program Changes in a sequence by recording them or using the Step Edit Insert command.
Of course, this only covers the MIDI data, not audio. To hear both the sound from the MPC1000 sampler and from your keyboard, the audio outputs of both units should be connected to a mixing board.
