Frosty,did you watch that video in my sig i was telling to check out?
its the same thing,just use your keyboard in this example instead of the drum machine :)
youve gone to preferences and set up the A-Pro,correct?
you have it checked off ?
keep in mind also that not the whole keyboard are the drums,only a certain section,try using the octave up/down arrows,try all keys.
the A-pro also might be in some setting where its locked in an upper octave,thats why i say,use the up/down arrows to range the octaves.
if it gets real bad,message me and tell me where you live,if the phone bills is within reason i can call you and walk you through it.
keep in mind frosty,something a lot of users do is forget the "input echo button"(okay,so im the "a lot of users")
without this button engaged,you'll hear nada bro.
