Hi Matt - thanks for remembering my challenge. So yep, I bought the MegaPak and have got a good chord sequence for Lullaby in Birdland - that's my model piece to learn on. I've got the whole thing down with tempo, styles, key and getting HiQ Midi, but unfortunately, the brass doesn't have that yet (according to BIAB today).
I must admit that I am not familiar with brass loops - where would I find such? Also, unfortunately, I do not have the ability to write horn arrangements. Can I take the brass accompinament that comes with BIAB and split it into solo instruments?
