Yes i tried, but we cannot assign After touch effect to SA2 buttons.
That is not surprising, the effects applied by the buttons are completely different from what AT applies, and during play would be extremely difficult to apply with the right timing even via a pedal.
AT is designed to allow us to modulate volume, filter and vibrato semi continuously as we play by the way we press the keys. Done properly this is capable of injecting extra expression smoothly into a performance, particularly slower tempos. But the playing technique needs to be learnt. If your hit on the keys during normal playing is too high there is insufficient headroom for AT to cut in when pressed more, and perhaps confusingly, it won't work. So practising with a more delicate touch which in itself can be no bad thing, listening and adjusting may help to learn.
You can also alter the extent to which the effects are applied to each voice (when played appropriately) in Voice Editor/Controller page3.
Sunny, it might help if you explain which of the effects are must haves for you and why you don't "like" to pressurise the keys. If you give up you will be unlikely to perfect the technique and the benefits of applying AT naturally to your playing will not be available to you.
