beat builder "problem"

HELLO , I explain my problem …
I tried to recover my rhythm synthesizer Korg PA600 but when I get my rhythm in the afternoon and works in BEATBUILDER I miss almost wholes instruments, normal because only the main ones in BEATBUILDER …
I 'm looking for a software for Mac in the same spirit as BEATBUILDER but with all the instruments and twelve o’clock general simplistic in use that will allow me to rework my rhythm to adapt to the pedals
thank you all
