Yes with midi to midi cable

What controller? Which port of the controller did you connect to which port on the Fantom? Did you do any configuration on either device?

Connect the MIDI Out port on your controller to the MIDI In port on your Roland device.
Make sure the controller is transmitting on the MIDI channel(s) your Roland device receives on.

Ok i want use fantom sound on midi controller
How can i use???

You can't transfer the sounds from the Fantom to the controller, you use the controller to tell the Fantom to produce sounds. That is why I recommended the connection that I did.

Yes, as per Eddie's suggestions.

You need to use the keys on the controller, but with the controller making no sound (if it does make any sound). The controller should however generate midi instructions, note on/off, etc. These instructions will go via the midi cable from the MIDI OUT of the controller to the MIDI IN of the Fantom, and the Fantom will make the sounds using it's own facilities. Just as if you were playing keys on the Fantom (if it has any). Note Eddie's comments about channels, some devices do not transmit MIDI on all 16 channels, some devices do not receive on all channels.

Connect things up, and see what happens. Let us know. As much detail as you can.
