When you making a material for performance you should make it as if you were recording an album. Use sequenced automation, calibrate levels on different patches and so on.

Where the supreme pleasure which is beyond senses is perceived through intelligence, having established himself there, he no longer wavers away from the Lord.
Gaining which he considers no other gain to be superior to that and abiding therein, he is not shaken even by the greatest of the sorrow.
