I have to play a song which has electric piano tone which has a good distinct accent sound and can also be played at different dynamics.
The problem is that you've to hit the key hard to make it accented (considering touch response here), which makes that note loud and vice-versa you have to hit the key hard to play loud, so you cannot play a note which is loud but not accented or vice-versa accented but not loud. I want to solve this problem. In my keyboard, I can change the voice/tone dynamics, by changing its reverb, vibrato, touch response (so much that I can even play an organ soft or loud, without the swell pedal), etc. So, if I know that there is some setting which controls the accent of a tone, that'll help me.
EDIT: My Keyboard is YAMAHA PSR-S-670.
Please help me with it.
