I am an old former Big Band reed player.I fixed up a bedroom studio
and using Band In A Box prepared background music for Blues and
Jazz ballads then imported them into GarageBand for further editing.
I then use my arrangements of saxophone quintets and enter all the tracks via microphone.I then solo.I just bought Logic Express and although the drum loops will be very useful I am having
problems figuring out how,for instance,the bass loops can be
used with all the chord changes and shifting key centers that most ballads have.I have the Apple Training Book but cannot find where this is addressed.Would appreciate anyone pointing me in the correct direction.
