[QUOTE]Originally posted by rikkisbears:

if you have 4 bars with a chord change in each bar cmaj/fmaj/cmaj/gmaj, you'd be inclined to transpose the fmaj & gmaj parts so that they became a cmaj part. Sometimes transposing works, sometimes it doesn't sound quite right..

In that way you know already the chords in that particular part. copy that part into the composer and for each part without transposing you to that manualy in the composer itself.
ie. from fmaj to cmaj. Getting Cmaj from Fmaj you have to lower 4 semitones (you can find this out on your keyboard).
If you are at the asterix which highlighted the chord and i.e. you see the F lower with the down arrow 4 times and the C note is highlighted in the screen press OK and then for the following note of the chord press the right button than the A or C note of the chord (still on the same asterix) is highlighted. press down 4 times and press ok. and so on.
