I loaded some pipe Organ WAV samples on Tyros4.The WAV samples have original church reverb effect(at the tail of the sample).When I played the samples through Ty4 Audio Player and could hear the reverb but when Tyros4 played this as a custom voice there was no reverb evident.I tried editing the voice to reduce the Release rate and make the note-end less abrupt but it works more like a sustain and still no actual reverb can be heard when played.I need natural reverb when i release the key of Tyros4,but Once the key is released Tyros does not play the audio in the tail of the file beyond the Loop End marker.
Here is the link which i have uploaded the test file (C-3 )note:

Is there any way to get natural reverb on key release? Please help.

Thanks,
Sunny.
