i'd like to have some more percussion with the next GPO release... apart the timpani and the snare, which are fine because they provid variations (two hits per note), i feel the necessity to have some more variation in hit cymbals, tam tam and gong. and also the bass drum should have more hits in orded to avoid to repeat always the same sample.
in addition to this, a thing that i would really love to have in GPO are some "hollywood" percussions... the ones that can shake the earth like in the "lord of the ring" soundtrack , and some other to add more "colour" to the rhytm parts!
and what about the already discussed idea to provide "midi packets" for rolls, crescendo, etc on the timpani/snare? :-)
