Finally I've worked out how to do quarter note triplets!!!!!! After some complicated maths that left me dazed and confused , I managed to work out that if you multiply your tempo by 1.5, and use either 2 bars of 3 over 4, or one of 4 over 4 and another of 2 over 4, then use the hold (or shots) function for each beat- you will have a bar of quarter note triplets (remember to put your tempo back to original in the following bar). I feel like such a fool- it's taken me years, and it's so simple. If this is a common trick, forgive me- I don't have time to examine all the posts. I hope that this helps others to get the most out of this incredible program. Depending on the style, you might not get the exact results, and it might take your tempo out of range, but keep fiddling and it will probably come right. I got fantastic results in a backing track that I made by using this trick.
