He is taking arranger keyboard lessons...

Yes that is possible here in Holland, it replaces the organ lessons from earlier days..

They learn play with arranger ... adn with 10 finger synth piano style, requirenets are a 61 key or more arranger keyboard...

I can't judge the sound of the casio, or thequallity of the actuall keys... From the YPG i tought the styles where rather thin compared to what i am used, the piano part tough was extraordinary..
