Hi freddy74 and welcome to the forums.
When you say you are loading different instruments, are you loading them into the same instrument slot as previously, or are you adding into a different slot?
If they are into the same slot, maybe the instrument range is different i.e. a violin has a different range to a bass guitar and so plays back fewer notes.
If they are into a different slot, make sure that you are using different MIDI channels to trigger the sounds.
Hope that helps. If not please come back with more detail.
