send commands from the MOTIF to the external MIDI keyboard to select the sound and then send MIDI to use that sound.

But how do I send the Grand Piano sound to the keyboard? But I would like to play other sounds on the performance of the motif ...

Some MIDI keyboards can send the right messages to do what you want but not all. It's not a universal feature. For those MIDI controller keyboards that support the feature - they each have a different way of sending the required messages. Some may have the buttons and menus on the controller to do what you want and others would require programming the controller using hosted (computer) software.

I've got two MIDI controllers here and I bet they're different than what you have. Therefore, I'll refrain from saying anything about how to setup your MIDI controller which, until now, has not been described (brand, model).

To have an external MIDI controller or computer change the sound on your Motif ES7, you would need to send the following MIDI messages:

PRESET BANK 1 (PRE1) Voices:
Send MSB=63, LSB=0, PC=1-128 depending on PRE1 voice you want. See the data list:
https://usa.yamaha.com/files/download/other_assets/0/333990/motifese2.pdf

... and see the data list for other voice banks. Generically, in order to reach everything you would need to send the MSB and LSB and PC. Just so you know, an "MSB" in this context is sending a CC #0 message with the value 63 decimal in the above PRE1 example. And "LSB" is sending a CC #32 message with the value of 0 decimal. "PC" or program change is not a CC message - it's a different message type (PC). Your MIDI controller must at the least support PC to change anything even if MSB/LSB is not available.

If you wanted to change the Performance using this method - it's possible. Look at the chart on page 65 of the document I linked above. It shows User Performances (1-128) can be accessed using MSB=63, LSB=64 and the PC number associated with the given Performance number.

I bought the midi cable today. I tried an old psr which only has the midi channel off or 1/16 option. Before buying a serious keyboard I would like to understand if I can move sounds independently of the sounds I use for the performance. I play Prog Rock and can't handle different sounds well with just 76 keys and volumes. The alternative would be to use the PC like Mcbook but everything changes and the Motif would sell it. But it has excellent sounds and in the end a Hardware is more live than the PC and more immediate. Then I connect the midi cable in to the motif, and out to the midi keyboard. Then from the midi keyboard I go to look for the sounds of the motif? Can you recommend a 49/61 frets not too expensive and very light? I would leave a sound or two there, then with the splits of the motif I do all the rest.

When I was using an ES era keyboard, I had the Performance number (or voice depending) on my sheet music. It would say something like "PRE1 E15". And when I saw this, I would press the PRE1 button then "E" button then "15" button. 3 button presses would load up any sound I wanted. 4 button presses if you count changing from Voice to Performance mode.

That would be easier than messing with your MIDI keyboard to do this.

I have his own motif sounds on the economic psr. And they both played with the same splits. So you can. But I'm not interested in replicating the same performance: I'm interested in playing other motif sounds on MIDI. U user explained a way but i didn't understand well

Assemble your desired collections of sounds as a user Performance and use my earlier guide to MIDI switch to your desired Performance. That is if your MIDI master can send the required messages.

That's one way.

Which midi keyboard, for example, should I buy? With what specific technical characteristics? More than the real time controls, which I would use on the motif when playing the motif, I need these characteristics.

Can you draw a diagram of what you want?

Would help us understand your setup better.

Some observations:
-- MIDI only transports information, not audio;
-- MIDI controllers do not generate sound, only MIDI data to be fed to sound generators/synthesizers;
-- If you want to control the Motif from a MIDI keyboard, you need to connect a MIDI cable from the OUT port of the keyboard to the IN port of the Motif; in your posts you seem to describe the opposite, a setup where the Motif sends MIDI to a controller, which shouldn't give you something useful.

I have not explained myself well, I apologize but it is complicated. The Motif has beautiful sounds for her age and I like them. I want to play both the Motif in real time and an external midi keyboard on which I want to play the Motif sounds. Then: Tape String and Organ Dave C split on Motif and Gran Piano on the MIDI keyboard. I connected MIDI IN on Motif and MIDI OUT on MIDI keyboard but this plays perfectly the same sounds and splits as the Motif. Jason says I have to use a MIDI keyboard which takes the information and then the sounds from the Motif with specific codes. Which MIDI keyboard does these things? The connection, however, at this point is reversed, I guess: MIDI OUT on Motif and MIDI IN on the master mute. Right? So the Motif would play its performances normally and I play the MOtif sounds on the master by selecting a specific program.

So just to get it right: you want to play some of the Parts on the Motif from the Motif keyboard and some other Parts from an external keyboard.

I'm not very familiar with the Motif, but on the MODX you can do that easily by setting the MIDI channels on the MIDI keyboard.

An example on how this works on the MODX, which has 16 parts:
I sometimes use a Studiologic SL73 MIDI controller exactly for what you describe. It can do 4 zones (splits or layers).

So if I want to play Parts 8,9,10,11 from the MODX, I'll set up the SL73 with 4 zones and set each zone to output on one of these channels: zone 1 on ch8, zone 2 on ch9 etc.

In this way I play Parts 1-8 from the MODX own keyboard, with whatever splits and layers I need, and 4 more Parts from the external keyboard.

As far as I know, on the Motif you have even more flexibility, as you can actually decide what channel each Part is receiving.

So for this type of control you need a MIDI keyboard that lets you set MIDI channels and preferably can simultaneously output on more than one.

But by doing so, how does MoDx understand that it is not using those channels that prologic asks for and shield them?

You have a setting, and I'm sure that one is on the Motif as well, which lets you disable Keyboard Control for a Part, effectively telling it to not respond to the internal keyboard.

All this stuff should be in the Motif manual.

On the ES to place sounds on different MIDI channels you need to utilize the master + song or pattern modes. This is not easy and it would be easier to use Performance mode and place your different sounds using key range so that your local Motif keys are not to play the alternate sound and your MIDI connected controller plays the other sounds. If you don't mind having a single velocity you could reserve say velocity 127 as the remote MIDI controller velocity (forcing it to always send this velocity) and scale the velocity of your Motif so it doesn't ever play 127. This way you can have one (or more) Parts of the Motif respond to velocity 1-126 and the other Part (or Parts) respond to only velocity 127. This would be a velocity split whereby you could have the key ranges on top of each other.

Is this option done from the Motif or from the master keyboard? I think the best option is the first you indicated but I need to find a master that allows me to send the correct sources.
