i haven't used pooled items much yet, because i only just realized what it was, and haven't done much midi yet since, but, for me, i need for the color of all pooled items to be the same, and change randomly. single items should be easy to unpool and repool. also, to be able to pool portions. so say you have 2 pooled items for a chorus, of say 4 bars, you should be able to cut the fourth bar, unpool that, and still have the first 3 bars pooled with the rest of your pooled items. also, identical items should be able to be pooled together. not sure exactly how is best this could be done, might be really tough, but i do agree that is important. maybe an extra indicator for pooled items would be good as well. to me, how reason works is very close to what i'd want for this.
