Hi there, folks I've been encountering a very strange problem and as it's consistent I assume I must be doing something incorrectly. I can't for the life of me figure it out though, so any help would be much appreciated! I have a song that I'm working on that has a midi bassoon. The track has already been created and there is a songs-worth of midi information on it. I'd like to change the instrument, so what I have done is, under "Track" menu I choose "New with Duplicate Setting". I then copy down the midi file. When I play this back it plays fine. However, as soon as I change the instrument (for example, I loaded up Trillian) although the instrument plays when I hit my midi keyboard the midi file no longer works. What the...??? Have I done something wrong? Is this a bug? How can I fix this? Many thanks for the help, folks! - Fredo BTW - 2.44 Ghz 12-core Mac Pro running 10.8.1 Logic Pro 9.1.7 with 24Gb ram.
